Clinicians should approach patients with suspected limb-girdle muscular dystrophy (LGMD) by suggesting:

A clinical approach to guide genetic diagnosis based on clinical phenotype, inheritance pattern, and associated manifestations For patients with suspected muscular dystrophy, clinicians should use a clinical approach to guide genetic diagnosis based on clinical phenotype, inheritance pattern, and associated manifestations (Level B). Clinicians should refer newly diagnosed patients with an LGMD subtype and high risk of cardiac complications for cardiology evaluation even if they are asymptomatic from a cardiac standpoint (Level B). In patients with LGMD with a known high risk of respiratory failure, clinicians should obtain periodic pulmonary function testing (Level B). Clinicians should refer patients with muscular dystrophy to a clinic that has access to multiple specialties designed specifically to care for patients with neuromuscular disorders (Level B). Clinicians should not offer patients with LGMD gene therapy, myoblast transplantation, neutralizing antibody to myostatin, or growth hormone outside of a research study designed to determine efficacy and safety of the treatment (Level R).

A 30 year-old male is involved in a bicycle accident. He presents to the ED with right forearm pain. On exam he demonstrates intact sensation, but impaired strength secondary to severe pain. Trauma x-rays reveal a distal radius fracture in which the distal radius fragment is volarly displaced. This type of fracture is known by which of the following names?

A distal radius fracture is typically caused by trauma or fall on outstretched hand (FOOSH). Distal radius fractures happen in two ways: the distal radius fragment is dorsally displaced (Colles fracture), or volarly displaced (Smith fracture). Both require orthopedic surgery consultation.

You are evaluating a 16 year-old male in your outpatient clinic. He is noted to have scoliosis. He relies on a wheelchair for mobility. On examination he has impaired coordination and dysmetria. What is his most concerning issue in the future?

A patient with this constellation of symptoms most likely has Friedreich Ataxia. These patients usually die from heart disease (HOCM) and thus, they require careful cardiac workup.

A 22 year-old male sustains a lateral ankle sprain. Anterior drawer of the ankle, and talar tilt tests are positive. You grab your ultrasound machine because you are concerned about a secondary injury to which of the following structures most likely?

A possible complication of lateral ankle sprains is a fibularis longus or brevis tendon injury. This is due to the fact that these tendons wrap around the lateral malleolus; thus, severe inversion forces can cause abrupt stretching and possible tearing of these tendons. Diagnostic ultrasound scan would be useful as an in-office, quick evaluation of the tendon anatomy.

an example of a semantic paraphasia?

A semantic paraphasia is the act of substituting a word with another from the same semantic class (i.e. orange instead of apple, or above example pencil instead of pen). A neologism is the creation of a new word that has meaning only to the speaker. Echolalia is when someone repeats words/sounds made by someone else. Using words with similar sounds, such as "dock" instead of sock", is an example of phonemic paraphasia.

During electrodiagnostic studies, the A-wave can be studied. Describe the characteristics of an A wave and what it means?

A-waves (also called the axon reflex - not a true reflex) are a very predictable, stable waveform that shows up somewhere between the F-wave and the direct motor response when recording F-waves from a muscle. It is the exact same waveform with every stimulation (same latency and amplitude). If present, A-waves indicate that there has been previous reinnervation involving the nerve to the muscle being studied.

B Pectoralis major The pectoralis major is innervated by C5-T1 roots of the brachial plexus. Triceps and latissimus dorsi are innervated by C6, C7, C8 roots. FDP is innervated by C7, C8, T1 roots.

Lubiprostone is used to treat constipation through the following mechanism:

Activating type 2 chloride channels to promote gastrointestinal motility Lubiprostone (Amitiza) is a newer medication that treats chronic constipation by increasing intestinal fluid secretion and promoting gastrointestinal motility through the activation of type 2 chloride channels. This improves transit and passage of stool.Peripheral mu-receptor antagonists (a) like methylnaltrexone are used to treat constipation related to opiate use. This action improves constipation without reversing analgesia. Docusate (c) and other surfactant laxatives lower the surface tension of stool, allowing water and lipids to penetrate and soften the stool. Bisacodyl (d) and other stimulant laxatives directly stimulate nerves in the colon to increase peristalsis

What medical condition would demonstrate the feature shown in this motor nerve conduction study?

Acute inflammatory demyelinating polyradiculoneuropathy (AIDP) The tracings above demonstrate temporal dispersion, which is pathognomonic for an acquired demyelinating disease, and is among the diagnostic criteria for acute inflammatory demyelinating polyradiculoneuropathy (AIDP), chronic inflammatory demyelinating polyradiculoneuropathy (CIPD), multifocal motor neuropathy (MMN), multifocal acquired demyelinating sensory and motor (MADSAM) neuropathy or Lewis-Sumner syndrome, and distal acquired demyelinating symmetric (DADS). Demyelination is not a feature of acute motor axonal neuropathy (AMAN), therefore temporal dispersion is not pathognomonic. Diabetic polyneuropathy and mononeuropathy multiplex are axon loss neuropathies.

Once a patient has reached age 50, the conduction velocity of their nerves will decrease by approximately how many meters per second for each subsequent decade?

After age 50, conduction velocity normally decreases by about 2 m/s per decade.

Which best describes anosognosia? ​

Anosognosia is defined as a disturbance of a person's ability to recognize disability or illness in oneself. It is thought to be related to hemineglect, a tendency to ignore the contralateral half of one's body or of external space, that follows damage to the parietal lobe (or rarely, the diencephalon), right more often than left. Patients may not recognize the hemiplegia (anosognosia), their arm (asomatognosia), or any external object to the left of their own midline. These phenomena may occur without sensory defects in patients who are otherwise neurocognitively intact.

The strongest restraint to valgus stress in the elbow is the:

What is the most common inheritance patter of hereditary neuropathy with liability to pressure palsy?

Autosomal dominant associated with PMP22

Prednisone functions by directly inhibiting the production of which of the following compounds?

Arachidonic acid Corticosteroids, such as prednisone, function by inhibiting the enzyme phospholipase A2 (PLA-2), which normally produces arachidonic acid. Without arachidonic acid, prostaglandins are also no longer produced. However, the direct effect of prednisone is to inhibit arachidonic acid production, which indirectly leads to decreased prostaglandins. NSAIDs directly inhibit the COX-1 and COX-2 enzymes, the effect of which directly inhibits the production of prostaglandins.

Which of the following is a feature of a complex repetitive discharge?

Arises from ephaptic activation of muscle fibers

A 22 year-old male presents to your clinic with the chief complaint of right foot and ankle pain with intermittent swelling. The pain is worse with athletic activity, and improved with rest. There is tingling in the dorsum of the foot. On exam, the dorsalis pedis pulse diminishes when the foot is placed into plantarflexion. What is the most appropriate diagnostic test to perform?

Arteriogram This patient is a classic presentation of popliteal artery entrapment syndrome (PAES), which involves the popliteal artery in the knee becoming compressed in the popliteal fossa due to an abnormal arterial course or knee muscles impinging upon it abnormally. It presents with lower limb swelling and pain with paresthesias due to nerve compression. The classic physical exam maneuver is to demonstrate decreased dorsalis pedis pulse when the ankle is plantarflexed (thus putting the gastrocnemius in a position to pinch the popliteal artery). Workup involves arteriogram to demonstrate abnormal arterial course or flow.

The most common etiology for ischemic stroke in children is:

Arteriopathy Arteriopathy is the most common cause of arterial ischemic stroke in children. Cardiac disease (congenital or acquired) and prothrombotic conditions (such as Factor V Leiden) are also causes of ischemic stroke in children. Arteriovenous malformations are a common cause of hemorrhagic (not ischemic) stroke in children

What is the consequence of placing the electrodes 2 cm away from active elctrode rather than 4 cm during SNAP?

As a general rule it is always useful to remember that most pathologies in the cervical spinal cord occur at the C5 or C5-C6 level.

An 80-year-old woman with a history of dementia diagnosed three years ago is brought to your clinic by her family. The patient had been gradually deteriorating but has been coping at home with family support. She is confused at baseline. Two days ago, she became incontinent of urine (unusual for her), more confused with occasional return to baseline cognition, disorganized and inattentive in her conversation with family. The family has noted increased lethargy. Balance has remained unchanged from baseline. Her change in symptoms is most consistent with:

As this patient has dementia, she is likely to be at a particularly high risk of delirium. Worsening dementia is likely, due to the long history and gradual deterioration, but not due to the increased confusion over the last two days. Increased sleepiness over two days (recent) is not conclusive of depression.

At rest, inhalation is a ______ process while exhalation is a ______ process.

At rest, inhalation is an active process initiated by diaphragm contraction, while expiration is (at rest) a passive process.

Which of the following is good practice to prevent electrical injury during electrodiagnostic studies?

Avoid extension cords Leakage current increases with the length of the power cord, therefore extension cords should be avoided. A is incorrect because ground electrodes should always be used to dissipate leakage current, therefore nerve conduction studies are performed with a reference electrode, and active electrode, and a ground electrode. The machine should be turned on before attaching electrodes to the patient and after disconnecting them. Using a stimulus pulse duration greater than 0.2ms in someone with an implanted pacemaker or cardioverter increases the risk that the stimulus may be misinterpreted as a QRS complex.

The American Geriatrics Society's goal of diabetic control in an otherwise healthy elderly individual includes:

Blood pressure below 140/90 American Geriatric Society guidelines place greater emphasis on reduction of cardiovascular complications and minimizing the risk of hypoglycemia. In an otherwise healthy elderly individual, fasting plasma glucose below 130 mg/dL and a hemoglobin A1c of less than 7.5% is sought.

how is brown sequard syndrome plus different from brown sequard?

BSPS is much more common than brown sequard syndrome. patients with BSS have greatest prognosis for ambulation and functional outcome. They also have a favorable recovery of bowel and bladder function. Motor recovery in BSPS usually takes place in the ipsilateral proximal extensors and then the distal flexors.

Orthostasis in the elderly can be exacerbated by decreased:

Baroreceptor response As many as 20% of persons over the age of 65 years and 30% of those over age 75 have orthostatic hypotension. Orthostasis is often exacerbated because of an increase in arterial stiffness, increased peripheral resistance, decreased baroreceptor response, and low plasma renin activity.

Which therapy approach is based on the concept that pathological movement patterns must not be used for training because continuous use of the pathologic pathways may make it too readily available to use at the expense of the normal pathways.

You are reviewing the medical chart for your next clinic patient. The patient is a 35-year-old female with a history of R breast cancer which was treated with partial mastectomy. You are consulted for lymphedema in the RUE since the surgery. The oncologist note states that she has grade I lymphedema. What does grade I lymphedema represent clinically?

Breast cancer (and its treatment) is the most common cause of upper extremity lymphedema. In grade I lymphedema, the edema is reversible with limb elevation. In grade 2 lymphedema, the edema is reversible with use of elevation AND stockings/massage, and fibrotic changes may begin to develop. Further extensive fibrosis and trophic skin changes develop in stage III; these changes are consistent with elephantiasis.

The patient is interested in trialing a medicine his friend recommended, topical capsaicin, but wants to know more about its mechanism of action; your attending asks you to explain the mechanism of action to the patient. You say?

Capsaicin depletes substance P, thereby decreasing pain transmission It is important to not only understand the indications for certain medications, but also how they work. Capsaicin acts by depleting substance P from nerve endings; substance P is a neuropeptide that has many roles, one of which is functioning as a neurotransmitter and modulator of pain. Carbamazepine's mechanism of action is inhibition of sodium channels on neurons. L type calcium channel blockade in the central nervous system is the mechanism of gabapentin (and pregabalin, which is structurally very similar). Inhibition of PLA2 enzyme is accomplished by corticosteroids.

On trauma imaging, he is found to suffer from a T12 spinous process fracture that extends all the way through the spinal column and into the vertebral body anteriorly. This is known as what kind of fracture, and patients often demonstrate what neurologic findings?

Chance fracture, normal neurologic exam

If patient has anterior dislocation of sternoclavicualr joint but has a normal x ray what test should you do next?

Chest CT

A child has been diagnosed with SMA. He is able to sit independently but has never been able to stand or walk. This level of function is most consistent with SMA type:

Classically, children with SMA type 1 never achieve independent sitting. Those with SMA type 2 are able to sit but not stand or walk. Standing and walking are achieved by those with SMA type 3 and 4, with later age of symptom onset in type 4.

Clavicle fractures most commonly occur at which portion of the clavicle?

Clavicle fractures most commonly occur within the middle ⅓ of the clavicle.

Characteristic neuromuscular manifestations of uncontrolled hypothyroidism include

Clinical manifestations of uncontrolled hypothyroidism include muscle weakness and pain. Polyneuropathy attributed to hypothyroidism is typically a demyelinating neuropathy that favors motor neurons. Upper motor neuron signs are not observed.

A 5 year-old boy with spina bifida has full hip flexion against gravity and his knee extension strength is at least 4/5. The child has ankle dorsiflexion but not plantarflexion. His feet are in neutral position. Hip examination is symmetric. What will most likely be this child's primary means of mobility as he grows older?

Community ambulation without assistive device This child has a strong quadriceps muscle and no deformities noted at 6 months of age. He is reported to be healthy. Sitting balance and neurologic level were good predictors of ambulation potential. The best early predictor of ambulation in children with spina bifida is a strong quadriceps muscle. Negative predictors are spine and lower extremity deformities and obesity. Children do not typically learn to use crutches until 3 to 5 years of age or older.

During gait observation, you notice that during stance phase of the left leg, the patient leans their torso laterally over their left leg. Which of the following muscles should be strengthened in order to treat this problem?

Compensated trendelenburg gait involves the patient essentially throwing their torso laterally over their weak leg (the left leg in this case) to compensate for the hip abductor weakness. Thus, to treat this abnormality, the gluteus medius of the leg being stood on during the gait abnormality should be strengthened. In practice, it is wise to strengthen the bilateral hip girdle musculature for muscular symmetry.

Which of the following is associated with clinically identifiable peripheral nerve damage?

Complex regional pain syndrome (CRPS) type I (also known as Reflex Sympathetic Dystrophy) generally develops after minor trauma or surgery and does not involve a clinically identifiable peripheral nerve injury. CRPS type II, previously known as Causalgia, is associated with damage to a major nerve. The sympathetic nervous system is also thought to play a role in the pathophysiology of CRPS, however it is not clearly understood. Sympathetic and catecholaminergic dysfunction may be responsible for autonomic manifestations in CRPS. The exact cause of phantom pain is unclear, but it appears to originate in the spinal cord and brain. In myofascial pain syndrome, sensitive areas in tight muscles, or trigger points, can cause strain and pain throughout the muscle and referred area.

The decrease in cardiac mortality from participation in a program of cardiac rehabilitation is:

Comprehensive cardiac rehabilitation programs that address reducing risk factors and lifestyle changes such as nutrition, weight loss and smoking cessation have an impact on cardiac mortality by reducing risk by 25%.

16 year old male baseball player presents with a one day od right arm pain and swelling. He denies trauma and reports that tha pain developed gradually over thecourse of the practice to the point where he stopped playing. He has no significant past medicl history or family history. physical examination is remarkable for visibly dilated veins and cyanosis of the right arm. What is the most appropriate diagnostic test to obtain in this patient.

Compression ultrasound fo the right arm patient has an upper extremity DVT known as Paget Schroetter syndrome. This is an axillary subclavian vein thrombosis associated with the strenuous and repetative activity of the upper extremities. the most appropriate diagnostic test is a compression ultrasound odf the affected extremity, but the gold standard test contrasts venography

A patient with aphasia demonstrates intact fluency and comprehension, but cannot repeat phrases. What type of aphasia does this patient have?

Conduction aphasia involves a lesion to the arcuate fasciculus of the left cerebral hemisphere, and produces impaired repetition with intact fluency and comprehension. Transcortical motor aphasia involves impaired fluency, but intact comprehension and repetition. Transcortical sensory aphasia involves impaired comprehension, but intact fluency and repetition. Anomic aphasia involves an essentially normal language output and comprehension, except the patient has difficulty naming objects and other nouns.

Which is associated with multidirectional instability of the shoulder? Congenital hyperlaxity of the glenohumeral joint or acute dislocation of the shoulder

Congenital hyperlaxity of the glenohumeral joint

Juvenile idiopathic arthritis (JIA) can be differentiated radiographically from ankylosing spondylitis (AS) by the:

Constellation of cervical facet joint ankylosis and vertebral body hypoplasia in patients with JIA By definition, JIA affects the immature, growing skeleton. Diffuse ankylosis of the cervical facet joints in the setting of vertebral body and disc hypoplasia is virtually diagnostic. In contrast, AS affects the mature skeleton after the intervertebral discs have formed. The cervical spine is more commonly involved in patients with JIA than other spinal levels with AA instability being the most common radiographic finding. Enthesopathy and tarsal disease in the first year of presentation is diagnostic for JIA even in the absence of axial disease. Klippel-Feil syndrome may be difficult to distinguish radiographically from JIA unless posterior element fusion is a dominant feature in the cervical spine.

What is the initial deformity created in the cervical spine in a whiplash injury?

A 50 year-old male is admitted following a motor vehicle accident (MVA). He is diagnosed with a traumatic brain injury (TBI). On MRI of his brain you note focal changes involving the medulla. What grade of diffuse axonal injury (DAI) would you assign to this patient?

DAI is graded on MRI criteria. A simplified grading method is as follows: Grade 1 = no focal changes on MRI. Grade 2 = focal changes on MRI. Grade 3 = brainstem involvement.

A 50 year-old male is admitted following a motor vehicle accident (MVA). He is diagnosed with a traumatic brain injury (TBI). On MRI of his brain you note focal white matter changes involving the medulla. What grade of diffuse axonal injury (would you assign to this patient.

DAI is graded on MRI criteria. A simplified grading method is as follows: Grade 1 = lobar white matter changes on MRI. Grade 2 = central white matter (corpus callosum) changes on MRI. Grade 3 = brainstem involvement.

While performing a nerve conduction study (NCS) you apply current to the nerve and detect a small amplitude. You then move distally on the limb and apply current again to the nerve. To your surprise, the amplitude is normal. What is the most likely explanation for this finding?

Decreased amplitude throughout an entire nerve's length suggests axonal loss. EMG will show decreased recruitment in these cases. Conduction block is seen with proximally reduced amplitude, but stimulating distally beyond the spot of conduction block can demonstrate a normal "repaired" amplitude.

What is an indication of success in an exercise training in a pulmonary rehabilitation program for patients with COPD includes which of the following?

Decreased dyspnea at rest and exertion

What would be some good prescriptions for medial column overload

Deep heel cup, semi rigid plate, or wide plate

THe --- Reflex may be the first of all reflexes to return , occurs within hours or days following SCI, and shows a high correlation with complete injuries and a poor prognosis for lower extremity motor recovery and function?

Delayed planter The delayed plantar reflex may be the first of all reflexes to return. Occurring within hours or days following SCI. Elicitation of this reflex is similar to that of the babinski sign but for deep pressure rather than a light stimulus. High correlation with complete injuries. If persisting for longer than 2 days, it is associated with a poor prognosis for lower extremity motor recovery and function.

Measurement of F-wave minimal latencies are a useful part of the electrodiagnostic workup for:

Demyelinating neuropathy F-wave minimal latency is notably prolonged (or absent) in demyelinating neuropathies such as acute and chronic inflammatory demyelinating polyradiculoneuropathy (AIDP, CIDP), and is among the electrodiagnostic criteria for demyelination

A 75-year-old patient was treated for local prostate cancer 15 years ago. He has received leuprolide (Lupron) for chemical castration since his diagnosis. He is currently asymptomatic with an undetectable prostate specific antigen and requests guidance in developing a comprehensive exercise program. Which study would be most useful in counseling this patient?

Dexa Chemical castration to reduce circulating testosterone levels places prostate cancer patients at risk for the development of osteoporosis. Given this patient's age and the extended interval of Lupron therapy, he is at risk for osteoporosis and should be screened before beginning exercise. Dual energy x-ray absorptiometry scan is the most sensitive of the studies listed for detecting osteoporosis.

In a 45-year-old man with a spinal cord injury (SCI) and a history of coronary heart disease, which risk factor is an indication for the most stringent control of low-density lipoprotein (LDL)?

Diabetes

The term diaschisis refers to which of the following?

Diaschisis in TBI patients refers to a TBI causing a "split across" type of injury. In this case, the TBI damages one region of the brain, and through neural network connections between this region and a distant brain region, the distant brain region also becomes damaged and dysfunctional. Even though the distant region was not directly involved in the trauma, its strong connections with the primary region of injury make it susceptible to injury if this primary region is traumatically damaged.

Diazepam's mechanism of action is best described as which of the following?

Diazepam is a GABA-A agonist, which increases presynaptic chloride influx into the axon, thus inhibiting action potential transmission; this is useful for reducing spasticity. Baclofen is a GABA-B (1 and 2) agonist, and dantrolene is a ryanodine receptor antagonist. All of these medications serve to decrease spasticity.

The most common site of maximum tenderness with a navicular stress fracture is:

Dorsally between the tibialis anterior and the extensor hallucis longus tendons

In patients with parkinsons planned for awale deep brain stimulation, what drug shoudl be avoided?

Duloxetine and pregabalin are FDA-approved to treat pain due to peripheral neuropathy in diabetes.

What is the strongest predictor of a seizure-related motor vehicle crash?

Duration of seizure free interval Seizures are responsible for 1% of all motor vehicle collisions. Minimum requirements for length of seizure-free time before a person can drive vary from state to state but range from 3-12 months. The strongest literature confirmed predictor of a seizure related motor vehicle collision is duration of seizure free interval. A 12-month seizure free interval prevents 80% of crashes. A 3-month interval prevents 50% of crashes. Other risk factors for motor vehicle collisions in individuals with seizures include age, gender, generalized or complex seizures, partial complex seizures, history of multiple seizures, and noncompliance with antiepileptic medications. The probability of a seizure related collision is decreased by a long seizure free period, reliable aura, and the use of the least sedating, but most effective, medication.

ETIOH withdrawal

The Brunnstrom method of rehabilitating a stroke patient aims to do what?

Encourage primitive reflexes and flexor synergy patterns to "use what the patient has"

Which attribute distinguishes end plate activity from fibrillation potentials? End plate spikes have initial negative phases Fibrillation potentials are less than 1.5 msec in duration End plate spikes fires regularly Fibrillation potentials are usually less than 150 microvolts

End plate spikes have initial negative phases End plate activity is generated when the needle is close to the motor end plate thus producing an initial negative phase since the potential is moving away from the recording electrode. End plate activity fires irregularly whereas positive sharp waves and fibrillations discharge regularly. The end plate spikes are fast and occur in a series. Fibrillations are slow at less than 5 Hz and 1-5 msec in duration and or 20- 200 µV in amplitude.

A 15 year-old obese male develops sudden-onset left hip groin pain. He walks with a trendelenburg gait. X-rays reveal 36% slippage of the femoral metaphysis under the epiphysis. Which of the following is important to screen for in this patient?

Endocrine Adolescent obese males are at greatest risk for slipped capital femoral epiphysis (SCFE), in which the metaphysis of the femur slips under the epiphysis (like ice cream falling off a cone). These patients require orthopedic surgery (ORIF) and screening for endocrine abnormalities such as growth hormone deficiency or thyroid disease. SCFE is graded on the % slippage that occurs. Grade 1: <33% slippage. Grade 2: 33-50% slippage. Grade 3: >50% slippage. There is no Grade 4.

Objectives of the Joint Commission include:

Eval of safety standards Joint Commission Disease-Specific Care Certification was established in 2002, and today has been achieved by more than 2,000 clinical care programs nationwide. Certified programs must demonstrate a systematic approach to care delivery and a commitment to performance improvement through ongoing data collection and analysis. The discipline and self-assessment inherent in meeting these requirements creates a road map to improving patient care quality. Licensure falls under the jurisdiction of state and federal governments

Endoskeletons weight less than exoskeletons

Exoskeletal prostheses are more rugged, require less maintenance, cannot be adjusted for alignment after fabrication, and can accommodate only a restricted number of foot and knee units. Furthermore, these prostheses tend to weigh more than the equivalent endoskeletal prostheses. For these reasons, exoskeletal prostheses are prescribed less often than endoskeletal prostheses. Endoskeletal prostheses are modular in design, allowing relative ease of adjustment of alignment and replacement of parts. They are also easier to suspend by virtue of their relatively lighter weight.

What is a pure motor late response which occurs after teh compound motor action potential?

F wave

Normal forced expiratory volume in 1 second (FEV1) decreases by approximately how many cc/year?

FEV1 normally decreases by 30 cc/year. In smokers it can be over double this rate.

Which of the following types of exercise places the greatest stress upon a tendon, leading to highest risk for tendon rupture? concentric or essentric? Fast or slow?

Fast essentric

Which of the following is the most common lower limb congenital limb deficiency?

Fibular hemimelia in general is the most common lower limb congenital limb deficiency. It involves the fibula bone itself being absent. PFFD involves a short femur. Patients typically also have a fibula deficiency, and a surgical procedure called a Van Ness Rotation is sometimes performed, involving rotating the foot around so that the ankle is effectively the new "knee", and the patient can be fitted for a lower limb prosthesis for ambulation.

In order to differentiate a lesion of the common peroneal (fibular) nerve from the deep peroneal (fibular) nerve at the fibular head, which muscle should be tested with needle electromyography? A. Long head of the biceps femoris B. Short head of the biceps femoris C. Peroneus (fibularis) longus D. Tibialis anterior

Fibularis longus

Which of the following maneuvers describes the Jerk test with respect to the shoulder?

Flexing the shoulder to 90 degrees, internally rotating, and adducting across midline with a posterior axial force describes the Jerk test, which is a test for posterior shoulder instability. The Kim test (flexing shoulder beyond 90 degrees and applying posteroinferior force) is also a shoulder posterior instability test. Abducting, externally rotating, and applying anterior force describes the anterior apprehension test, which unsurprisingly tests for anterior shoulder instability.

You are caring for a patient after traumatic brain injury who presents with hyponatremia. Labs reveal elevated urine osmolality and decreased serum osmolality. What is the most appropriate treatment for this patient?

Fluid replacement with normal saline This patient has cerebral salt wasting (CSW). Fluid restriction is the treatment for SIADH while fluid replacement with normal saline is the treatment for CSW. Desmopressin (DDAVP) is used in Diabetes insipidus. Mannitol is used for elevated intracranial pressure after TBI.

Gait speed

Which organ system is responsible for the leading cause for rehospitalization for medical complications after a traumatic spinal cord injury?

Genitourinary Overall, diseases of the genitourinary system such as urinary tract infection are the most common reason for rehospitalization, followed by diseases of the skin (pressure ulcers), then respiratory and musculoskeletal systems. Respiratory diseases were more likely associated with hospital admission in persons with tetraplegia, while diseases of the skin were more likely associated with rehospitalization in those with paraplegia.

Botulinum toxin injections should not be performed when a patient is taking which of the following, due to potentiation of the botulinum toxin?

Gentamycin Aminoglycoside antibiotics can potentiate the effect of botulinum toxins and botulinum toxins should not be utilized for patients taking this class of antibiotic. Other medications that can potentiate the effect of botulinum toxins include quinidine, anticholinergics, and curare-like compounds.

Which patient population meets the criteria for approved payment for cardiac rehabilitation by the Centers for Medicare and Medicaid Services?

Heart failure with ejection fraction of 30%, 7 weeks after discharge from the hospital The Centers for Medicare and Medicaid Services (CMS) made the decision to approve payment for cardiac rehabilitation based on the inclusion criteria of HF-ACTION trial, the largest randomized clinical trial of cardiac rehabilitation (CR) for patients with heart failure (HF) sponsored by the National Institutes of Health. This specifically includes those with symptomatic heart failure with reduced ejection fraction (HFrEF≤35%) who have not been hospitalized for at least 6 weeks and who did not have a planned major cardiovascular hospitalization or procedure in the past 6 months. Though heart failure with preserved ejection fraction (HFpEF ≥45%) is the most common type of HF among older adults, such patients are usually not covered for CR by CMS due to lack of evidence.

A 34 year-old female complains of pain across her upper back. You diagnose her pain as myofascial in etiology. You recommend trying conversion thermotherapy in the form of which of the following? Ultrasound Hot water whirlpool Cold pack Heat pack

Heat packs and cold packs are a form of conduction thermotherapy. A whirlpool is a form of convection thermotherapy which utilizes gross molecule movement to transfer heat. Conversion thermotherapy involves using a source of one type of energy which is converted to heat, such as using ultrasound (sound waves) to heat deep tissues.

The Fee for Service Model of payment makes separate payments to providers for the services that providers give to beneficiaries for a single illness or course of treatment (episode of care). This model of payment promotes:

Increased service utilization The Fee for Service Model results in increased service utilization since payment is based on how much a provider does, not how well the provider does in treating the patient The Bundled Payments Initiative aims to improve care through a patient-centered approach, emphasizing care coordination and quality. Though limited evidence-based literature regarding bundled payments currently exists, recent data indicates: (1) bundled payments may reduce spending for an episode of care; (2) bundled payments can promote quality improvements in care.

A 31 year-old male is playing tennis. In an attempt to impress his girlfriend, he tries to catch a 130 mph serve with his bare hand. Shockingly, this does not occur as intended, and he develops sudden-onset finger pain. After delivering this blistering serve and declaring that you swung with minimal effort, you rush over to examine his finger. On exam, you notice swelling of the distal interphalangeal joint (DIP) of his index finger. There is pain with varus stress testing of the DIP. X-rays are negative for acute fracture. What is the most appropriate initial step in management? Dynamic varus stress testing under ultrasound Orthopedic surgery referral Immobilization splinting for the DIP

Immobilization splinting for the DIP This patient has sustained a radial collateral ligament injury/sprain/tear of his index finger DIP joint. X-rays have ruled out fracture of the finger/hand, so the most appropriate step is to allow the ligament to heal by using either buddy tape or an extension splint for the finger the prevents flexion, varus, and valgus forces about the DIP. This is not a surgical issue at this point.

. What is the best orthotic management for an acute knee grade 2 medial collateral ligament sprain?

Immobilizer

What is the primary goal of treatment with orthotic bracing for scoliosis from neuromuscular disease?

Improve sitting posture in wheelchair Scoliosis in neuromuscular disease is very common and can begin early and progress quickly. Neuromuscular curve progression is rarely slowed by bracing. Orthoses may be beneficial because they can stabilize a weak trunk, and improve sitting posture in those using wheelchairs. Bracing may cause instability for ambulatory patients however, increasing the risk for falls. Rigid spinal bracing has a negative effect on vital capacity.

A 77 year-old male undergoes a transfer during physical therapy and complains of sudden-onset severe low back pain. X-rays diagnose a T10 vertebral body compression fracture. Which of the following bracing recommendations is most appropriate?

In cases of vertebral body compression fracture, CASH (cruciform anterior spinal hyperextension) or Jewett braces are recommended in order to maintain a neutral (non-flexed) spine position to prevent worsening of the compression fracture via hyperflexion forces. A soft lumbar corset will not provide sufficient stabilizing force to resist spine flexion. A flexion-biased brace is the opposite of what is indicated in these patients. Bracing is not contraindicated in these cases (quite the opposite, as discussed!).

Isometric vs isotonic vs isokinetic exercise

In isometric exercise, no movement occurs throughout the entire exercise. In isotonic exercise, the weight (tone) being applied to a muscle or joint is the same throughout the entire exercise (e.g. biceps curls - the dumbbell weighs the same, and, thus, imparts the same forces onto the arm for the entire exercise). In isokinetic exercise, the movement and rhythm of the exercise is the same throughout the entire exercise (e.g. cardiovascular machines such as the elliptical, cycling, rowing).

In a patient with bilateral knee and finger pain, symmetric joint space narrowing, and positive anti-CCP antibodies, which of the following synovial fluid study results is the most likely?

In rheumatoid arthritis (i.e. this patient) synovial fluid analysis shows increased neutrophils (approximately 75% predominance) with elevated, but under 100k WBC. In septic arthritis the joint fluid may show >75% neutrophils with > 100k WBCs.

A patient requires assistance for transfers. This is defined as:

In simpler terms, impairments, disabilities, and handicaps can be defined as follows. An impairment is essentially a loss of structure or function (e.g. wrist drop). A disability is inability to perform ADLs (e.g. inability to ambulate or perform self care). A handicap reflects the patient's ability to navigate societal constructs (e.g. cannot climb stairs to reach office at work; paraplegia resulting in loss of work as a professional cyclist).

An 82 year-old male sustains a fall, resulting in spinal cord injury. Neurosurgery performs a spinal decompression and fusion. You are consulted on this patient 2 weeks following his injury. On examination you note impaired sensation to light touch and 0/5 strength in bilateral lower extremities. You also note absent Babinski, anal wink, and bulbocavernosus reflexes. Which test may ultimately offer prognostic information in this patient?

In spinal cord injury patients, typically the Babinski reflex returns after 24 hours of initial spinal shock (occurring immediately after injury). Following that, the anal wink and bulbocavernosus reflexes begin to return. In this patient 2 weeks following his SCI, if still none of these reflexes has returned, it may indicate lower motor neuron injury, e.g. cauda equina syndrome. In these cases, EMG of the lower extremities and pudendal nerves is most useful to offer prognostic information on the health of these nerves. In general the optimal time to wait before performing EMG is 4-6 weeks following peripheral nerve injury. Remember that cauda equina syndrome is really a peripheral nerve root injury, and thus, amenable to EMG.

The most common category of spinal cord injury is:

Incomplete tetraplegia According to the National SCI Database, from SCI Model Systems data collected since 1973, incomplete tetraplegia makes up approximately 45% of spinal cord injuries followed by incomplete paraplegia, complete paraplegia, and then complete tetraplegia.

Clinical symptoms and signs of tethered cord syndrome include

Increase in scoliosis The most common clinical signs or symptoms of a tethered cord include spasticity in the lower extremities, decline in lower extremity strength, and worsening scoliosis. Other signs and symptoms that strongly suggest tethering of the spinal cord include back pain, changes in urologic function, changes in gait, changes in sensation, and development of lower extremity contractures.

Leptomeningeal disease is located:

Intradural and extramedullary

Patients with which type of brain injury are most likely to have deep vein thromboses?

Intraparenchymal hemorrhage In a large study, patients with both penetrating (10.5%) and nonpenetrating (6.4%) traumatic brain injury had lower rates of deep vein thrombosis than did patients with nontraumatic brain injuries (16.3%). Among the latter group, patients with brain tumors had the highest incidence (21.2%), whereas those with hypoxic brain injury had 9.6% incidence and those with intraparenchymal hemorrhage had 14.6%.

What lower limb deformity are children with L4 spina bifida most likely to have?

Knee extension contractures The knee extensors (quadriceps) are innervated at the L3-4 level, while the knee flexors (hamstrings) are innervated at the L5-S1 level. A child with L4 preserved level would have quadriceps muscles that work, while hamstrings will either be weak or absent. Foot muscles are innervated at the L5-S2 levels. Equinus and cavus feet result from asymmetric pull of foot muscles, which would be seen in levels of spina bifida L5 and distally.

Lambert Eaton has autoantibodies that target what?

Lambert-Eaton myasthenic syndrome (LEMS) is an acquired disorder resulting from autoantibodies targeting the presynaptic P/Q voltage-gated calcium channels and possibly another presynaptic component (synaptotagmin), leading to a reduction in acetylcholine release.

Deficiency in what results from a mutation of chromosome 6, of autosomal recessive inheritance. Absence of this protein results in hypotonia at birth, severe weakness of the trunck and limbs, and contractures of the feet and hips. Seizures occur in up to 20% of patients. White matter abnormalities may be evident on imaging. A partial deficiency causes a milder phenotype.

Laminin alpha 2

Which type of nerve fibers is responsible for vibration perception?

Large, myelinated sensory fibers Vibration, proprioception, light touch, and deep tendon reflexes are all dependent on large, mye-linated sensory fibers. Small, myelinated and unmyelinated sensory fibers are responsible for pin prick and pain sensation, cold perception, and light touch.

A patient develops lateral knee pain, worse with skiing downhill. He notes that running downhill also causes this pain. On exam, varus and valgus stress testing is negative, as is McMurray, Thessaly, Apley grind, Lachman, posterior drawer, patellar grind, and patellar excursion. There is no tenderness to palpation throughout the knee. He denies stiffness, swelling, numbness, tingling, or pain when going up or down stairs. What is the most likely diagnosis?

Lateral knee pain worse with running downhill or skiing downhill is a classic presentation of popliteus tendonitis. The popliteus muscle unlocks the knee and is located laterally within the knee joint. Treatment involves rest, ice, NSAIDs, and physical therapy.

9 year old boy with limop fo r8-9 months, right thigh pain, right hip stiffness, flexion contracture of right hip, right leg is slightly externally rotated. pain with internal rotation and abduction of right leg. X ray shows a flattened right femoral epiphyses and inferior and lateral displacement of the proximal femur. What is diagnosis?

Leg calve perthes child 4-11 radiographs may be normal

Which of the following is an example of an isokinetic exercise?

Leg press Planks Elliptical machine Biceps curls In isometric exercise, no movement occurs throughout the entire exercise. In isotonic exercise, the weight (tone) being applied to a muscle or joint is the same throughout the entire exercise (e.g. biceps curls - the dumbbell weighs the same, and, thus, imparts the same forces onto the arm for the entire exercise). In isokinetic exercise, the movement and rhythm of the exercise is the same throughout the entire exercise (e.g. cardiovascular machines such as the elliptical, cycling, rowing).

5 year old boy has pain in his right hip, limping, no recent injury or illness, pain with extremes of ROM, no TTP, CBC normal, x ray with small joint effusion with mixed lucency and sclerosis at the femoral head. What is the most likely diagnosis and what is your differential?

Legg Calve Perthes disease Septic arthritis sickle cell anemia slipped capital femoral epiphysis transient synovitis

An 8 year-old male presents with gradual onset right hip pain for the past 1 month. He denies trauma, numbness, tingling, or weakness. He has no past medical history, and has maintained a normal body mass index (BMI). He suffered from an upper respiratory infection (URI) 2 weeks ago, but otherwise has been well. Hip x-rays demonstrate sclerosis of the femoral head. Which of the following is the most likely etiology of this condition?

Legg-Calve-Perthes disease involves idiopathic loss of blood supply to the femoral head, leading to femoral head avascular necrosis (AVN), which can be seen on x-rays as femoral head sclerosis and ultimately femoral head collapse. Treatment may involve observation, rest, bracing, physical therapy, pain control, and/or orthopedic surgery. Slipped capital femoral epiphysis and transient synovitis would demonstrate sudden-onset hip pain, not gradual. This patient has not had trauma, per the question stem, and trauma would more likely cause sudden-onset pain regardless.

Which of the following is the most common pediatric cancer?

Leukemia is the most common pediatric cancer. Astrocytoma and medulloblastoma are the most common solid pediatric cancers (brain tumors). Osteosarcoma is the most common primary bone cancer overall.

Dop responsive dystonia is characterized by a diurnal variation of symptoms. Age of onset is 4-8 years. tone increases throughout the day. often misdiagnosed as cerebral palsy. How do you treat?

MOVEMENTS THAT WOULD CAUSE VALSAVE

A patient presents with progressive, unrelenting low back pain. Two months ago, an uncomplicated diskectomy successfully relieved the patient's radicular symptoms. Which imaging study would most likely confirm the diagnosis at this time? A. X-ray of lumbosacral spine B. Magnetic resonance imaging with contrast C. Ultrasound D. Three-phase bone scan

MRI

A 45 year old women is referred to your clinic as a result of lower back pain and abnormal gait. the patients gait is found to be stiff legged and further observation reveals some spasticity. there is mild to moderate lower extremity weakness with clonus achilles reflex noted on both sides. in addition, there is detrusor hyperreflexia. Which of teh following is th emost liekly diagnosis. MS Herniated lumbar disk infection muscular dystrophy

MS

MVO2 aka cardiac consumption is what formula

MVO2 = HR x SBP HR xSV = cardiac output VO2 Max = CO xAVO2

Which of the following aids in prognosticating outcomes of TBI at 6 months post injury?

Magnetic resonance spectroscopy Magnetic resonance spectroscopy (MRS) provides information about the neurochemical status of the brain and may indicate the extent of brain damage; therefore, it provides important data for evaluating expected outcome. Studies found that MRS studies correlated with outcomes 6 months later. Furthermore, several studies found threshold levels for the metabolites that also correlate with prognosis. Positron emission tomography (PET) uses radioactive tracers that localize to metabolically active regions. PET scanning is more sensitive in detecting abnormalities after traumatic brain injury than is standard neuroimaging, although PET has poor specificity and has not been studied in regard to prognostic value. Earlier studies suggest that the presence of apolipoprotein-E4 allele (APOE-e4) would indicate a worse functional outcome, but that finding has not been replicated. There are conflicting reports on APOE-e4. It is unlikely that a patient's APOE-e4 status will play a role in prognostication at the present time. Transcranial magnetic stimulation is useful in examining cortical motor representation after cerebral injury and may be useful in treatment of TBI but has not been studied in regard to prognostic value.

Regarding the cardiovascular status of a patient after acutely sustaining a spinal cord injury, it is important to?

Maintain a mean arterial blood pressure at or above 85 mm Hg as this is associated with enhanced neurologic recovery

Which wheelchair would be most appropriate for a 50-year-old man who had a stroke with right hemiparesis?

Which of teh following procedures are critical in the initial management of acute spinal cord injuries? -Measure forced vital capacity and arterial blood gas -standard radiographic trauma series -avoiding insertion of nasogastric tube -provision of texas or condom catheter

Measure forced vital capacity and arterial blood gas a VC less than 1 liter indicates an extreme ventilatory defect with impending need for assisted ventilation.

A patient suffers a stroke and he is transferred to the stroke rehab unit after medical stabilization. He is seen by physical, occupational, and speech therapies. He has significant aphasia during the initial H&P encounter. You contemplate melodic intonation therapy as a means to help this patient; which type of aphasia below could melodic intonation therapy benefit? Broca aphasa Wernicke aphasia Conduction aphasia

Melodic intonation therapy can be useful for patients with nonfluent aphasia, including Broca's aphasia. The other answer choices are fluent aphasias. Melodic intonation therapy recruits the right hemisphere (speech is typically a left hemisphere activity) by incorporating melodies or rhythms into communication.

Melodic intonation therapy is most useful for which type of aphasia?

Melodic intonation therapy is a speech therapy technique most useful in patients with impaired fluency and repetition, but intact comprehension (Broca aphasia). The patient's fluency is impaired, but by drawing from, and utilizing the abilities of the intact right hemisphere in melody/prosody processing, a patient's fluency can be improved.

Mirabegron promotes urine storage in the bladder by stimulating which of the following receptors?

Mirabegron is a Beta-3 receptor agonist, which is theoretically very selective for the bladder wall, and promotes urine storage.

A patient who enjoys playing racquetball presents to your office with a trigger finger. You proceed with a corticosteroid injection. What would be your immediate next step in the treatment of this patient?

Modify RAQUET HANDLE A trigger finger is a stenosing tenosynovitis. It develops due to repetitive trauma that causes an inflammatory process to the flexor tendon sheath of the digits. This process forms a nodule in the tendon resulting in abnormal gliding through the pulley system. As the digit flexes, the nodule passes under the pulley system and gets caught on the narrow annual sheath resulting in the finger locked in a flexed position. In an athlete, it often occurs in racquet and club sports. A nodule forms from overuse or direct pressure at the flexor tendon sheath which leads to mechanical catching under the A1 pulley at the MCP level. A corticosteroid injection into the nodule or thickened tendon sheath can improve symptoms in up to 90% of cases. Modification of the racquet handle or grip may facilitate recovery, therefore the immediate next step in the treatment of this patient after a corticosteroid injection would be to recommend the patient modify the grip on their racquet handle. Splinting the finger in extension is not beneficial to the patient. There is no need for referral to the hand surgeon as 90% of patients treated with a corticosteroid injection will benefit from the injection. There is also no need to repeat the injection in 2 weeks as the most immediate next step in treatment would be to modify the causative agent of injury.

A 37-year-old male with Becker Muscular Dystrophy presents for a bracing evaluation. He is noted to have full passive range of motion in all lower extremity joints. Manual muscle testing shows 4/5 initial strength in hip flexors/extensors and knee flexors; 3/5 knee extensors, and flaccid dorsiflexors. The patient ambulates without assistive device for 20 feet with a hyperextended trunk, reciprocal gait pattern, and increased step height. Initial contact occurs through bilateral forefeet, with moderately severe bilateral knee hyperextension at midstance. Which bilateral AFO design will minimize weight, maximize compliance and prevent genu recurvatum?

Molded articulated thermoplastic AFO with a plantarflexion stop set in slight dorsiflexion Although a knee-ankle-foot orthotic would be the ideal choice, most patients with moderate to severe lower extremity weakness find them too heavy, and contribute to overall fatigue. Remembering closed chain kinetics, knee extension will be encouraged by plantarflexion of the ankle, and discouraged by dorsiflexion. The flexibility of a posterior Leaf Spring thermoplastic AFO or spiral AFO, though lightweight and assisting with foot drop, will not prevent this patient's knee hyperextension (genu recurvatum). A solid thermoplastic with anterior malleolar trim lines aligned in dorsiflexion will inhibit the knee hyperextension by promoting knee flexion. If too much dorsiflexion is permitted, his knee may buckle due to knee extensor weakness. Additionally, adjustments in ankle alignment will be difficult to achieve given the solid nature of this brace.

45 year old woman presents with pain and numbness in her left leg and arm. She also developed motor and sensory deficits over the past few days. her pain is in the area of the posterior thighthat is innervated by the sciatic nerve as well as her left forearm in the area supplied by the ulnar nerve. The patient denies any history ofd back pain, falls, or accidents. She denies any sphincter dysfunction or incontinence. What is her diagnosis?

Mononeuritis multiplex. This is a diffuse disorder that is similar to periopheral neuropathy but is distinguished by the involvement of multiple individual nerves. MM is usually the result of sichemic insult to nerves and the most common etiology is small or medium vasculitis. MM occurs in most cases of sytemic vasculitis and maybe its presenting symptoms. MM typically presents with the acute onset of severe pain and numbness in the involved limb, motor and sensory deficits develop over days.

patients with bells palsy will have what on EMG?

Myokymic dsicharge rippling appearnce to overall skin. fascial myokymia can also be due to MS, brainstem neoplasm, polyradiculopathy

Myoplasty involves suturing the muscles to each other, and is technically easier. Myodesis involves suturing the muscles into the bone, produces a more stable surgical result, but is contraindicated in patients with severe dysvascular disease, as it will not heal properly due to the poor blood supply. Myodesis Myoplasty Myotomy

Myoplasty involves suturing the muscles to each other, and is technically easier. Myodesis involves suturing the muscles into the bone, produces a more stable surgical result, but is contraindicated in patients with severe dysvascular disease, as it will not heal properly due to the poor blood supply.

NSAIDs (nonsteroidal anti-inflammatory drugs) reduce pain by reducing the production of which of the following compounds?

NSAIDs inhibit the COX enzyme, which reduces COX's production of prostaglandins. Prostaglandins mediate inflammation. Thus, inflammatory pain is reduced by using NSAIDs.

describe the NYHA cardiac functional classification as NYHA Class 3? NYHA class 1 NYHA class 2? NYHA Class 4?

NYHA cardiac functional classification as NYHA Class III. NYHA Class III patients will be comfortable at rest but otherwise have significant limitations; they can typically perform activities between 2-5 METS (metabolic equivalent). NYHA Class I patients have a cardiac disease that does not limit physical activity including activities >7 METs. NYHA Class II patients are comfortable at rest but ordinary activity causes symptoms, and these patients can perform activities between 5-7 METs. NYHA Class IV patients are unable to carry on any physical activity without discomfort and are usually limited to 2 METS or less.

With Polio, what do sensory nerve studies look like on NCS?

Normal

Which electrodiagnostic finding is most compatible with early stage anterior horn cell disease?

Normal motor conduction studies In anterior horn cell diseases such as amyotrophic lateral sclerosis (ALS), the sensory nerves are not usually affected. In the early stages of the condition motor nerve conductions can be normal. Because ALS is a neuropathic condition with ongoing denervation and reinnervation, one would not expect to find small amplitude motor units with early or increased recruitment; that pattern represents a myopathic process.

Which of the following is the most normal/ideal synovial fluid white blood cell count (WBC)?

Normal synovial fluid WBC should be zero (0) or nearly zero.

In patients with degenerative disc disease of the lumbar spine, what percentage of weight do the zygapophyseal joints bear?

Normal zygapophyeal joints weight bear 33% of the total compressive load. Those with just zygapophyseal arthritis bear up to 47% and those with degenerative disc disease bear up to 70%.

When viewing magnetic resonance imaging (MRI) of the cervical spine, which tissue type is dark on a T1-weighted image and bright on a T2-weighted image?

Nucleus pulposis

A patient with mutations in the survival motor neuron 1 gene (SMN1) would most likely benefit from which of the following medications?

Nusinersen is FDA-approved to treat spinal muscular atrophy (SMA). Riluzole and pyridostigmine are not (they treat ALS and myasthenia gravis, respectively).

A 24 year old male has right hip pain. in training to pass his test for the military he has been running everyday. For the past 2 weeks he has noticed some discomfort in his groin area. Usually the pain is better with rest but worsens as he runs. He has a history of adductor muscel strain last year but no other past issues. He has some discomfort with ambulation. on exam there is mild discomfort on deep palpation of his right grion. He has a normal range of motion of his hip with some discomfort at extremes ranges. His exam findings are otherwise normal, including his genito urinary exam. Pelvis films with a lateral right hip study are normal. WHat is the best next step in management?

OBtain MRI, the patient should be non weight bearing on crutches A stress fracture of the femoral neck is a major cause of groin pain, especially in athletes or military recruits with rapid increases in physcial activity. This involves a gradual onset of groin pain, which poorly localized and aggravated by activity.

List risk factors for plantar fasciitis

Obesity is a risk factor for plantar fasciitis. Plantar fasciitis affects both men and women equally, most commonly between the ages of 40 and 70 years. Factors that increase the tension on the plantar fascia, such as decreased subtalar motion, pes cavus, pes planus, and a tight Achilles' tendon, may contribute to plantar fasciitis.

Which of the following is the most common type of amputation?

Of those listed, transmetatarsal amputations are the most common. Consider that in lower limb amputations, dysvascular disease (the most common cause of lower limb amputations) tends to affect the limb distally > proximally.

You are discussing your patient's new knee-ankle-foot orthosis (KAFO) with the patient's orthotist. She mentions that she intentionally offset the KAFO's hinge joint to sit posterior to the patient's knee. Which of the following is the most likely purpose of offsetting the hinge posterior to the patient's knee? A To promote knee flexion To cause the line of gravity to fall anterior to the knee to offset the anteriorly placed AFO components

Offsetting the hinge joint of a KAFO serves the purpose of moving the line of gravity anterior to the patient's knee, which then tends to lock the knee in extension, producing a stable knee during ambulation that locks appropriately and will not buckle. This is useful in patients with weak quadriceps (not spastic quadriceps) who need extra assistance in extending/locking the knee during ambulation. Promoting knee flexion would occur if the hinge were fixed anteriorly to the patient's knee.

Which of the following juvenile idiopathic arthritis (JIA) subtypes requires ophthalmology referral? RF: rheumatoid factor.

Oligoarticular JIA requires ophthalmology referral, as this subtype is associated with iridocyclitis/uveitis.

The most common organism responsible for septic arthritis in a one-year-old is:

Overall, the most common organism responsible for septic arthritis is Staphylococcus aureus. However, in children ages 2 months to 2 years old, the most common organism is Hemophilus influenza. Neisseria gonorrhea is the most common agent for septic arthritis in sexually active adolescents.

A 12-year-old boy presents to you for right ankle pain. His parents brought a recent MRI, and a grade 3 osteochondritis dissecans lesion is noted at the talar dome. You recommend:

Osteochondritis dissecans is a disorder characterized by loss of integrity of the subchondral bone in a focal area of the joint. The injury may be staged with MRI, with conservative measures such as splinting, rest, and physical therapy being valid options for grade I (continuous with underlying bone) or II (partially continuous) lesions; however, grade III (discontinuous but not dislocated) and IV (loose body) lesions require referral to an orthopedic surgeon for consideration of surgical fixation, removal, or other procedures.

You are caring for a patient with a severe burn and malnutrition on the acute rehabilitation unit and looking for an additional agent to support nutrition during his recovery process. Which of the following is an anabolic steroid that is FDA-approved to promote weight gain after severe physiologic stress?

Oxandrolone is an anabolic steroid that is FDA-approved to promote weight gain after severe physiologic stress, such as a burn with hypermetabolic state. Vitamin C is an essential nutrient in wound healing because of its role in collagen formation. Zinc is a stimulant for DNA syntheses and may have a beneficial effect on wound healing. Dronabinol is a cannabinoid medication that is used to treat loss of appetite and weight loss.

Which of the following is optimal initial treatment for congenital hip dysplasia in infants less than 6 months?

PAVLIK The Pavlik harness is the first line treatment. It is a brace which fastens around an infant's legs and connects to the shoulders and torso to prevent mal-tracking of the femoral head within the acetabulum. Spica casting requires a series of hip casting to prevent femoral acetabular dislocation. Abduction braces are generally prescribed after completion of a spica cast series. Closed reduction is not the best initial treatment.

Needle EMG of the TA and extensor digitorum brevis (EDB) reveals decreased recruitment. Needle EMG of remaining muscles is normal. Which of the following is the most appropriate response to these findings? A MRI is recommended B Ultrasound-guided intervention is recommended C Surgical opinion should be sought D Prognosis for recovery is good Explanation: This patient's results demonstrate neurapraxia of the common fibular nerve, likely due to some physical injury sustained during the soccer match. Neurapraxia can be differentiated from axonotmesis (axon loss due to crush/stretch injury) and neurotmesis (axon loss due to complete nerve transection) due to the normal CMAPs present below the level of injury at 2 weeks out from injury. There is also the lack of active denervation (fibrillations and positive sharp waves) that suggests neurapraxia rather than axon loss. Neurapraxia, you recall, manifests as a conduction block, as in this case (normal amplitude CMAP distal to the lesion, decreased amplitude CMAP proximal to the lesion). Neurapraxia/conduction block represents a focal demyelination event; thus the axons are intact, and all that is required is remyelination for the CMAP, recruitment, and patient's strength to recover. If this were axon loss, the CMAP ampli

A collegiate runner presents to you with pain overlying the tuberosity of the 5th metatarsal. You are concerned for a possible Jones fracture, but X-ray and MRI are both negative for fracture. Tendonitis of which muscle is the likely culprit for pain overlying the tuberosity of the 5th metatarsal?

Pain along the lateral aspect of the foot, specifically overlying the base or tuberosity of the 5th metatarsal, should prompt consideration of fibularis brevis tendinopathy. This tendon inserts onto the 5th metatarsal tuberosity. This is the same anatomic location that should alarm clinicians to the possibility of a Jones fracture. The fibularis longus tendon inserts onto the medial cuneiform and 1st metatarsal bone. The tibialis anterior tendon inserts onto the medial cuneiform bone and the base of the first metatarsal bone. The tibialis posterior tendon inserts primarily onto the navicular bone.

Which of the following spinal cord injury levels is most likely to necessitate ventilatory support?

Patients with cervical spinal cord injury (SCI) are at especially increased risk of respiratory insufficiency, chiefly due to diaphragm denervation. The phrenic nerve controls the diaphragm (the body's chief muscle of inspiration), and is innervated by C3, C4, C5 nerve roots. Thus, a patient with a C6 level SCI would be expected to still possess complete voluntary diaphragm control. However, patients with C3/C4/C5 injuries may have loss of diaphragm function secondary to phrenic nuclei injury within the spinal cord. The higher the injury in the spine, the more nervous tissue in the inferior (distal) spinal cord will be affected. Thus, the higher the level of injury (C3 in this case), the most loss of diaphragm control will take place.

A 27 year-old male is running a marathon when he trips and lands on his right shoulder. He experiences immediate severe shoulder pain. On exam, there is asymmetry when comparing his right shoulder to his left. You diagnose an anterior shoulder dislocation. This patient's ultimate treatment will most likely be which of the following?

Patients with traumatic unilateral shoulder dislocations typically require surgery.

Which of the following juvenile rheumatoid arthritis (JRA) subtypes requires ophthalmology referral? RF: rheumatoid factor.

Pauciarticular JRA requires ophthalmology referral, as this subtype is associated with iridocyclitis/uveitis.

Which peripheral nerve innervates the bladder to stimulate bladder emptying via detrusor contraction?

Pelvic "Parasympathetics Pee Pelvic": the pelvic nerve carries parasympathetic fibers which innervate the detrusor muscle, which then contracts to cause bladder emptying. Credit to Dr. Amanda Harrington for this great mnemonic!

Which massage technique has as its goal the breakup of tissue and muscle adhesions?

Petrissage

The modality of utilizing sound waves to push medication through the skin and deeper tissues in order to reach a target structure is known as:

Phonophoresis is the correct answer. Iontophoresis is the concept of using electricity to drive ions through the skin towards a target structure. Magnetophoresis and transdermophoresis are not actual modalities.

What is the most common cause of death in patients with ventilator-dependent tetraplegia who have survived the first 24 hours?

Pneumonia

A patient presents to you for evaluation for left leg weakness. History is significant for fever, headache and myalgias a few days prior to the acute onset of nonprogressive flaccid paralysis of left lower leg. Patient denies any difficulty with speech or swallow. Exam is significant for weakness in left lower leg, muscle atrophy, decreased tone and areflexia. CSF shows elevated proteins and pleocytosis. MRI shows increased T2 signal in the region of ventral horn of spinal cord. EMG shows multifocal denervation. What is the likely diagnosis?

Polio

You are performing serial EMGs on a patient. Over time you notice that while he used to demonstrate polyphasic motor unit action potentials (MUAPs) in a particular muscle, on his most recent EMG these polyphasic potentials have been replaced by larger, non-polyphasic potentials. What is the most reasonable explanation for this finding?

Polyphasic potentials represent ongoing reinnervation due to collateral sprouting of existing axons. The polyphasic property arises due to non-uniform myelination of these collateral sprouts during this early reinnervation stage. Once myelination is complete, the motor unit's branches all conduct the action potential at essentially the same speed, producing a nice, uniform "roller coaster" bump (uniform-appearing MUAP) rather than the polyphasic, serrated potential seen in unmyelinated collateral sprouts

What is an advantage of intermittent positive pressure breathing (IPPB) devices for patients with postpolio syndrome?

Portability

Which of the following findings on an electrodiagnostic study would help diagnose Myasthenia Gravis? Increment at baseline Decrement immediately after exercise Post-activation exhaustion 3 minutes after exercise Post-activation potentiation immediately after exercise

Post-activation exhaustion 3 minutes after exercise Post-activation exhaustion refers to the smooth decrement of at least 10% that occurs 2-4 minutes after exercise as a feature of Myasthenia Gravis (MG). At baseline, there is no increment in neuromuscular junction disorders. Post-activation potentiation refers to the increment after exercise or high frequency repetitive stimulation in Lambert-Eaton Myasthenic Syndrome. Immediately after exercise there is a repair of the baseline decrement in MG.

Which therapy approach uses spiral and diagonal components of movement rather than the traditional movements in cardinal planes of motion with the goal of facilitating movement patterns that will have more functional relevance than the traditional technique of strengthening individual group muscles

Proprioceptive neuromuscular facilitation

Which of the following mediators is released from macrophages and neutrophils that act as vasodilators and increase microvascular permeability after burn injury?

Prostaglandins Prostaglandins are released from macrophages and neutrophils and act vasodilators increase microvascular permeability. There are a few inflammatory mediators released during thermal injury. Histamine causes an increase in arteriolar dilatation and tissue pressure, leading to increased microvascular permeability. Thromboxane is produced by platelets. There is minimal effect on vascular permeability. Catecholamines cause arteriolar vasoconstriction.

A 74 year-old female falls onto her outstretched hand and sustains a proximal humerus fracture. On xrays, you notice that the humerus is intact except for the greater tuberosity which is displaced. What is the next best step?

Proximal humerus fractures are classified using the 4-part classification system. In 1-part fractures, the humerus remains as one whole part (intact), with no elements displaced off the humerus. These are treated with a sling. In 2-part fractures, one of the 4 "parts" (greater and lesser tuberosities, humeral head, humeral shaft) is displaced from the other 3, thus leaving 2 "parts" of bone existing in the proximal arm: the displaced fragment and the still intact other 3 parts. In 3-part fractures, 2 of these parts are broken off, and in 4-part fractures, all 4 of these parts are separated from one another. 2-4 part fractures require surgery, as in this question's case.

A 75-year-old female presents to clinic with a large, cool synovial effusion of her right shoulder. Physical examination is significant for pain-limited range of motion (ROM) and profound rotator cuff muscle weakness. X-rays of the patient's shoulder reveal superior subluxation of the humeral head, extensive bony destruction of the glenohumeral joint, soft-tissue effusion, and calcific deposits. The most likely diagnosis is:

Pseudogout The patient presents with a classic "Milwaukee shoulder" - MSS is a destructive, calcium phosphate crystalline arthropathy; it encompasses an effusion that is noninflammatory with numerous aggregates of calcium hydroxyapatite crystals in the synovial fluid, associated with rotator cuff defects . Calcium hydroxyapatite crystal disease is characterized by recurrent painful periarticular calcific deposits in tendons, soft tissues, or intra-articular surfaces. The pathophysiology is believed to be the intra-articular calcium hydroxyapatite deposition. MSS occurs in elderly patients typically aged 60-90 years. There is a female preponderance in the ratio of 4 : 1. Radiographic changes on plain X-ray show joint space narrowing, subchondral sclerosis with cyst formation, destruction of subchondral bone, soft-tissue swelling, capsular calcifications, and intra-articular loose bodies.

A 45-year-old patient with a history of hyperparathyroidism presents with recurrent episodes of knee pain. X-rays reveal chondrocalcinosis of the medial and lateral menisci. The most likely diagnosis which would account for the patient's pain and x-ray findings is:

Pseudogout chondrocalcinosis = Pseudogout A definitive diagnosis of CPPD arthropathy (ie, pseudogout) requires the identification of CPPD crystals from joint fluid; however, the radiologic findings in this case are diagnostic. CPPD deposition disease can be associated with hyperparathyroidism, hemochromatosis, and amyloidosis. It is weakly associated with hypothyroidism. Chondrocalcinosis is not seen in osteoarthritis, monosodium urate crystal arthropathy (ie, gout), or Paget's disease.

A 63-year-old patient with amyotrophic lateral sclerosis presents to your clinic with insidious onset of dyspnea over the last several months. What is the most likely abnormality on pulmonary function testing?

Reduced Tidal volume In restrictive lung disease, the primary abnormality is low tidal volume. In extrinsic restrictive lung disease (neuromuscular disease including amyotrophic lateral sclerosis, paralysis and kyphoscoliosis), this is due to weakness of the chest wall muscles. In intrinsic restrictive lung disease (pulmonary fibrosis, sarcoidosis), this is due to noncompliant lung tissue. In obstructive lung disease (asthma, COPD), abnormalities include increased residual volume and reduced forced expiratory volume due to incomplete exhalation or obstruction.

In the treatment of lymphedema, which condition is a relative contraindication to performing complete decongestive therapy?

Relative contraindications to complete decongestive therapy include significant congestive heart failure, acute deep venous thrombosis, acute or untreated infection or inflammation of the affected limb, and fracture. Lymphatic drainage massage should be avoided over concurrently irradiated soft tissues, but a history of previous radiation therapy is not a contraindication for therapy.

Which technical error can artificially increase (prolong) distal sensory latency when performing antidromic sensory nerve conduction studies?

Reversing the stimulator anode and cathode Depolarization occurs under the cathode with hyperpolarization beneath the anode. Placing the anode over the measured stimulus site and the cathode proximally results in depolarization more proximally, effectively increasing the distance between the stimulus and recording electrodes, and prolonging the distal sensory latency. An increase in the stimulus intensity or pulse width results in wider spread of the site of depolarization some distance from the cathode, effectively reducing the distance between the stimulating and recording electrodes, and shortening the distal sensory latency. The reference electrode should be placed more than 4 cm distal to the recording electrode; a shorter interelectrode distance has the effect of reducing SNAP amplitude and shortening the distal sensory latency due to differential amplitude effects of common mode signals being recorded.

A 52 year-old male who was previously active and healthy begins to notice muscle twitching and difficulty swallowing salivary secretions over the course of 2 months. He then begins to notice some weakness in his right arm and left leg. Electrodiagnostic studies reveal probable amyotrophic lateral sclerosis. He is started on riluzole by his neurologist. At his initial consultation with you, he asks you about the mechanism of riluzole. You respond with:

Riluzole blocks glutamate action in the central nervous system Amyotrophic lateral sclerosis is a progressive disease of upper and lower motor neurons. The median survival rate is 2-3 years after diagnosis, however the median survival rate is 1 year after diagnosis in those with bulbar symptoms. Treatment consists of physical therapy and submaximal exercise in addition to consideration of assisted ventilation and early nutritional intervention to supplement calories. Riluzole is an antiglutamate medication that has been shown to slow disease and prolong ventilator time.

Which part of the scaphoid bone has poor blood supply, rendering scaphoid fractures at that location susceptible to which feared complication?

Scaphoid fractures present following trauma/FOOSH (fall on outstretched hand) and typically cause pain in the anatomic snuffbox. X-rays/CT scan/MRI may reveal a fracture of the scaphoid; if this fracture occurs within the proximal ⅓ of the bone, orthopedic surgery consultation is required. If within the distal ⅔ of the bone, thumb spica cast is appropriate. If initial x-rays are negative for fracture, but you still suspect a scaphoid fracture, place thumb in thumb spica cast and repeat x-rays in 2 weeks, as the fracture may reveal itself at that time. You can also consider CT/MRI if x-rays are negative. Pain in the anatomic snuffbox is a scaphoid fracture until proven otherwise, even if initial x-rays are negative.

The conjoint hamstring tendon houses which tendons?

Semitendinosus, biceps femoris

A 30 year-old male develops left knee pain and swelling associated with fever. Synovial fluid analysis shows 130k WBCs with 97% neutrophils. What is the most likely etiology for this disease?

Septic arthritis in adults is typically due to N. gonorrhea infection. Synovial fluid analysis in septic arthritis reveals > 100k WBCs and overwhelming neutrophil (PMN) predominance. Septic arthritis in children is typically due to staph aureus.

In an inpatient rehabilitation setting, greater functional gains are typically seen in which individuals with which diagnosis? TBI ischemic stroke primary brain tumor metastatic brain tumor

Several studies have shown significant functional improvements from admission to discharge as measured by Functional Independence Measure (FIM) scores. Overall FIM change, FIM efficiency, and discharge to home rates were comparable between primary and metastatic tumor groups. Patients admitted to inpatient rehabilitation facilities with a diagnosis of traumatic brain injury tend to have greater total FIM change compared to patients with brain tumors. Patients admitted to inpatient rehabilitation facilities with a diagnosis of stroke appear to have equivocal total FIM change compared to patients with brain tumors. However, one study noted a greater FIM efficiency in the tumor cohorts. Researchers have found that patients who received chemotherapy or radiation during inpatient rehabilitation did not have a significant difference in length of stay (LOS) or FIM gains when compared to those who did not.

A 42 year old female presents with a cervical disk herniation at C 5-C6 on magnetic resonance imaging. SHe complains of radicular pain down her lateral left upper extremity to the thumb for 6 months as well as numbness of the elft thumb. No left upper extremity weakness is noted. Her EMG is normal and reveals normal nerve conduction of the left upper extremity of teh cervical paraspinals. What isthe most likley explanation for this patients normal nerve conduction and EMG studies?

She has a pure sensory lesion of the cervical nerve roots a pure sensory lesion of the nerve roots may be present in a normal EMG study

Which of the following is commonly used as an outcome measure to assess perception of physical and emotional functioning in patients with chronic pain?

Short Form 36 The SF-36® and the shorter SF-12® is a measure of quality of life with questions covering multiple domains. SF-36 Domains include "physical functioning; role limitations due to physical health; role limitations due to emotional problems; energy/fatigue; emotional well-being; social functioning; pain; general health". These questionnaires are owned and marketed by Medical Outcomes Trust. They have a considerable research base and assess a broad range of activities of daily living relevant to disability.

A 4-year-old child suffers an ankle inversion. When you examine him the following day, he has mild swelling laterally and is tender to palpation approximately 2-3 cm proximal to the distal aspect of the lateral malleolus and he reacts to pinch. The remainder of the examination is limited due to pain. Radiographs appear normal. What is the management of this patient?

Short leg non-weight bearing cast for 3 weeks Given the mechanism of injury, location of pain, and "normal" radiographs, the boy likely has a Salter Harris I Fracture of the distal fibular physis. A Salter Harris I fracture is a transverse fracture through the hypertrophic zone of the physis, and is typically not visible on radiographs though there may be widening of the growth plate. A walking boot is not sufficient to immobilize the ankle joint in a toddler. A CT scan is not required given there is not any significant abnormality on radiographs. A MRI to rule out an ATFL tear is not indicated. There is a significantly greater likelihood of a bony versus ligamentous injury.

Which of the following imaging findings is most consistent with congenital cervical stenosis?

Shortened pedicles

Which of the following lab results would you expect to see in classic Sjogren syndrome? ANA: antinuclear antibody. RF: rheumatoid factor.

Sjogren syndrome classically is ANA+ and RF+.

A 14 year-old male with a history of obesity presents with sudden-onset left hip pain. He denies trauma. He has been healthy other than a diarrheal illness 2 weeks ago. Hip x-rays demonstrate a widened growth plate and femoral head sliding off the growth plate by approximately 40%. Which of the following grades could correctly be assigned to these x-ray findings?

Slipped capital femoral epiphysis (SCFE) involves sudden-onset hip/groin pain due to the femoral head sliding off the growth plate, typically in obese adolescent males. X-ray grading is defined by the percentage of slippage of the femoral head off the growth plate. Grade 1: 0-33% sliding. Grade 2: 34-50% sliding. Grade 3: >50% sliding. There is no grade 4. Treatment is orthopedic surgery.

Which of the following is a recommended static alignment for an uncomplicated transtibial amputee with no significant knee contracture?

Socket positioned in 5° to 10° of anterior tilt (flexion) The socket is prepositioned in 5° of adduction and 5° to 10° of anterior tilt. The anterior tilt allows loading of the soft tissues of the anterior surface of the residual limb. The foot is slightly inset relative to the socket. The patella tendon bar is located halfway between the tibial tubercle and the distal end of the patella. The posterior brim of the socket should end about an inch below the patella tendon bar, with relief made for the hamstring tendons.

A 67 year-old female with a history of facial trauma presents with complaints of crying every time she eats. She denies any actual emotional disturbances. What is the most likely etiology of this problem?

Synkinesis is the inappropriate regeneration of the facial nerve after it is damaged, leading to the nerve reinnervating muscles inappropriately in such a fashion that the patient may end up doing two "facial nerve" activities at once when the patient only means to do one of these. For example, blinking and moving their mouth at the same time, or salivating whenever they cry.

A patient presents with pain in his ring finger after an opponent tried to slap a basketball out of his hand. On exam flexion and extension of his DIP is intact. X-ray of his finger shows a non-displaced distal phalangeal fracture. What is the next step in his treatment?

Splint immobilizing DIP joint only The goal of treatment for any finger injury is to restore the normal function of the finger. Restoration of bony anatomy is the basis for returning normal function; however, an anatomic reduction is not always necessary to achieve this goal, especially if it comes at the cost of soft tissue scarring and loss of motion. Early motion prevents adhesions of the gliding soft tissues of the extensor and flexor tendon systems and prevents contracture of the joint capsules. Immobilization of fingers much beyond 4 weeks will lead to long-term stiffness due to extensor tendon and joint capsular scarring. For example, non-articular phalangeal fractures treated with closed reduction and splinting are mobilized after 3-4 weeks, once the fractured phalanx is less tender. Even if splinting of one joint is needed, splints should be made small enough to allow early motion of uninjured joints. Therefore, in a case of a non-displaced distal phalanx fracture splinting that immobilizes the DIP joint only is sufficient. Closed non-displaced or minimally displaced fractures with acceptable alignment that are the result of a low-energy trauma usually have sufficient supporting tissues remaining intact making them stable and amenable to treatment by protected mobilization, either with local splinting of the fracture or buddy taping to adjacent fingers. Fractures with rotational or angular misalignment may be amenable to closed reduction and splinting, but these fractures are at risk for incomplete reduction and recurrent deformity. These more unstable fractures require careful and frequent clinical and radiographic follow-up. Surgical treatment is indicated for any fractures of the articular surface, open fractures, fractures with significant shortening or malrotation, and fractures which fail closed reduction. Delayed treatment of these surgically indicated fractures is always more difficult, with worse functional outcomes due to stiffness, incomplete deformity correction, and post-traumatic arthritis.

A 61 year-old male presents with low back pain radiating down the bilateral lower limbs with numbness and tingling in the legs. MRI of the lumbar spine demonstrates 55% slippage of the L3 vertebral body on top of the L4 vertebral body. X-rays reveal no dynamic instability. On exam he has intact strength, sensation, and reflexes. What is the next best step?

Spondylolisthesis is the slippage of one vertebral body over the top of another. Grade 1 is 1-25% displacement when comparing the two vertebral body surfaces. Grade 2 is 26-50% slippage; grade 3 is 51-75% slippage; grade 4 is 76-100% slippage; grade 5 is beyond 100%. Grades 1 and 2 can be managed with PT. Grade 3 if asymptomatic (other than low back pain) can be managed with PT. Grade 3 with neurologic symptoms should have a surgical consultation. Grades 4 and 5 require surgical consult.

Which stage of complex regional pain syndrome (CRPS 1) is characterized by burning pain, dependent edema, and vasomotor instability?

Stage 1, the acute phase, is characterized by burning pain, dependent edema, redness, hyperhidrosis, coolness to touch. Stage 2, subacute phase, is characterized by severe pain, fixed edema, and cyanosis or pallor. Stage 3, chronic phase, pain may have subsided, edema subsided, and the extremity is generally stiff. There is no defined 4th stage. The three clinical stages of type 1 complex regional pain syndrome (CRPS 1) are acute, subacute, and chronic. The acute form lasts approximately 3 months. Pain, often burning in nature, is one of the first symptoms that initially limits function. Swelling, redness with vasomotor instability that worsens with dependency, hyperhidrosis, and coolness to the touch are common physical find-ings. Demineralization of the underlying bony skeleton begins because of disuse. If the process is not arrested or reversed in the acute phase, the condition may progress to the subacute stage, which can last for up to 9 months. The patient develops persistent severe pain in the extremity and fixed edema that would have been reversible with elevation during the acute phase. The redness of the acute stage gives way to cyanosis or pallor and hyperhidrosis to dry skin. Loss of function progresses, both because of increased pain and fibrosis of the joints caused by chronic inflammation. In the hand, this leads to flexion deformity of the fingers. The skin and subcutaneous tissues begin to atrophy. Demineralization of the underlying bony skeleton be-comes pronounced. If the process continues, the chronic phase may develop approximately 1 year after disease onset. This stage may last for many years or can be permanent. Pain is more variable during this period. It may continue undiminished or abate. Edema tends to subside over time, leaving fibrosis around the involved joints. The skin is dry, pale, cool, and shiny. Flexion and extension creases are absent. Loss of function and stiffness are marked, and osteoporosis is extreme. In the upper extremity, this can manifest as a frozen shoulder and claw hand.

Bilateral radiculopathy of which spinal level will theoretically not cause impaired storage of urine or impaired bladder contraction? S2 L4 L2 T12

Storage of urine is controlled by the pudendal nerve innervation of the external urethral sphincter via S2-S4 nerve roots, and the hypogastric nerve's innervation of the internal urethral sphincter via T11-L2. The hypogastric nerve also innervates the bladder wall promoting relaxation. For bladder contraction and voiding, the pelvic splanchnic nerve (S2-S4) causes detrusor contraction and relaxation of the internal urethral sphincter. In the above question, only L4 is a nerve root not involved in the innervation of the detrusor muscle or either the internal or external urethral sphincter.

The Americans with Disabilities Act protects individuals from employment discrimination if they have a physical or mental impairment that:

Substantially limits a major life activity Employment discrimination is prohibited against qualified individuals with disabilities. An individual is considered to have a disability if she or he has a physical or mental impairment that substantially limits one or more major life activities such as seeing, hearing, speaking, walking, breathing, performing manual tasks, learning, caring for oneself, and working. A qualified individual with a disability is a person who meets legitimate skill, experience, education, or other requirements of an employment position that she or he holds or seeks, and who can perform the essential functions of the position with or without reasonable accommodation. Reasonable accommodation is any modification or adjustment to a job or the work environment that will enable a qualified applicant or employee with a disability to participate in the application process or to perform essential job functions. Employers are not required to lower quality or quantity standards as an accommodation; nor are they obligated to provide personal use items such as glasses or hearing aids.

Which blood vessel is most likely to compress the trigeminal nerve?

Superior Cerebellar artery The most often cited vascular structures associated with trigeminal neuralgia (in order) include the superior cerebellar artery, the anterior inferior cerebellar artery, the posterior inferior cerebellar artery, and the superior petrosal vein.

A physiatrist is using ultrasound to examine a patient's shoulder. What is the anterior boundary of the rotator interval?

Superior aspect of subscapularis tendon Improper identification of the rotator interval may lead to false diagnosis. The rotator interval is bordered anteriorly by the superior aspect of the subscapularis tendon and posteriorly by the anterior aspect of supraspinatous tendon. Contents of the rotator interval include the capsule, superior glenohumeral ligament, coracohumeral ligament, and long head of the biceps tendon. The rotator interval is best viewed with the patient in modified Crass position which allows for inspection of the intracapsular biceps tendon. The biceps tendon will appear hyperechoic on ultrasound with a hypoechoic separation from the supraspinatus.

Describe the path of the F wave

Supramaximal stimulation ,an antidromic motor response to anterior horn cells which produces an oprthodromic motor response that travels back to the recording electrode.

Which of the following nerves is associated with the spinoglenoid notch? Axillary nerve Dorsal scapular nerve\ Suprascapular nerve

Suprascapular nerve The suprascapular nerve innervates the supraspinatus, then passes through the spinoglenoid notch to innervate the infraspinatus. This is an important anatomical consideration when performing an EMG involving both supraspinatus and infraspinatus. The axillary nerve passes through the quadrilateral space of the axilla.

A 6-month-old boy with right Erb's palsy is not able to bring his right hand to his mouth and has weak wrist extension. His right upper extremity passive range of motion is within normal limits. Which of the following is the most appropriate next step in treatment?

Surgical referral This patient demonstrates weakness in elbow flexion noted by inability to reach the mouth. Surgical intervention is commonly recommended for those having less-than-antigravity strength in elbow flexion by 6 months of age. Patients with Erb's palsy who had surgery at 6 months did better than those who spontaneously recovered elbow flexion at 5 months.

A patient who had a right MCA stroke presented one hour after symptom onset and received intravenous thrombolysis with t-PA, improving his NIHSS from a 12 to a 5. He is ambulating with physical therapy on the acute medical floor. Which factor has greatest evidence to predict his chances of going home?

TPA within the first 3 hours Patients who receive intravenous thrombolysis for acute ischemic stroke are more likely to be discharged directly home after hospitalization with outpatient neurorehabilitation therapies. There is no correlation with the exact time within the three-hour window. His premorbid functional status, location of stroke, and early mobilization are important components of his rehabilitation; however, they have no bearing on the efficacy of t-PA therapy.

Talar body (AKA talar dome) fractures carry the highest risk of AVN over other types of talus fractures; thus, they require orthopedic surgery referral.

What test is the best method for determining level of amputation?

TcPO2 The transcuatneous oxygen pressure is used to find the level of amputation with enough blood perfusion to increase chance of succesful wound healing and decrease risk for re amputation. Based on clinical research studies, a median TcPO2 of 28 mmHg is likely to provide sufficient

What is the anatomic location of a stroke which produces impaired expression, comprehension, and repetition, with normal fluency?

Temporal gyrus

While on inpatient rounds on the stroke unit of the rehab hospital, your attending discusses the various rehabilitation methods. Which method focuses on normalization of tone and inhibition of primitive patterns of movement?

The Bobath approach is described in the question stem, with a focus on normalization of tone and inhibition of primitive patterns of movement at its core principles. The Brunnstromm Approach uses primitive synergistic patterns to attempt to improve motor control. The Rood Approach attempts to modify muscle tone and voluntary motor activity using cutaneous sensorimotor stimulation. Lastly, the proprioceptive neuromuscular facilitation uses spiral and diagonal movements with the goal of facilitating more functional movements rather than attempting to strengthen individual muscle groups.

In the Brunnstrom stages of recovery from hemiparetic stroke, at what stage does the patient develop peak spasticity?

The Brunnstrom hemiparetic stroke recovery stages are as follows: ○1 = totally flaccid ○2 = spasticity, hyperreflexia, UE flexor synergy pattern, LE extensor synergy pattern ○3 = spasticity peaks; control over synergy patterns begins ○4 = spasticity decreases; control is maximized ○5 = complex voluntary movements ○6 = spasticity gone ○7 = normal

The extensor digitorum attaches to which of the following structures? Distal phalanx Proximal phalanx Both distal and proximal phalanges

The ED muscle attaches to a thick piece of tissue called the extensor expansion, which pulls on both the DIPs and PIPs, causing extension of both.

Which of the following muscles is innervated by the listed neural pathway? S1, S2; sciatic nerve; tibial nerve; medial plantar nerve. Abductor digiti quinti pedis (ADQP) Flexor hallucis brevis (FHB)

The FHB is innervated by this pathway, as well as the abductor hallucis brevis (AHB). The FHL and FDL are tibial nerve-innervated. The ADQP is lateral plantar nerve-innervated.

Which of the following receptors, when stimulated, increases presynaptic chloride influx into the neuron?

The GABA-A receptor causes presynaptic chloride influx into the axon. The GABA-B1 receptor inhibits presynaptic calcium influx into the neuron. GABA-B2 increases postsynaptic potassium conductance out of the neuron. All of these effects serve to reduce synaptic transmission of action potentials. Tizanidine binds to alpha-2 receptors to stimulate them, which inhibits the spinal reflex arc.

The Gate Control Theory of pain modulation functions due to which of the following anatomical principles?

The Gate Control Theory is based on the anatomic principle that large-diameter light touch fibers transmit their impulses onto the same neurons in the spinal cord's substantia gelatinosa as do smaller-diameter pain fibers, thus allowing light touch impulses to inhibit the transmission of pain impulses up to the brain by "taking over the sensation transmission highway".

List the HLA B 27 spondyloarthropathies

The HLA-B27 spondyloarthropathies include psoriatic arthritis, ankylosing spondylitis, oligoarticular JIA, enteropathic arthropathy, and reactive arthritis (formerly known as Reiter syndrome).

A 41 year-old male attempts to squat down and lift a car by reaching his hands under the rear bumper and lifting upward. He feels sudden onset anterior left elbow pain. You suspect a distal biceps tendon tear and perform the Hook test. All of the following are possible reasons for a false negative Hook test except which choice?

The Hook test involves placing the patient's elbow in 90 degrees of flexion and using the examiner's finger to try to "hook" the distal biceps tendon out of the elbow; a negative test indicates a firm, intact biceps tendon which is properly attached to the radial tuberosity; a positive test reveals a floppy "wet noodle" biceps tendon, indicating distal biceps tendon complete tear. All of the following answer choices could lead to a negative Hook test that is falsely negative, except palpating an intact brachioradialis tendon, which would be distal to the elbow and not within the elbow crease; the brachioradialis muscle is also lateral to where the biceps tendon would be palpated via the Hook test. By performing the Hook test in someone with a biceps tendon tear, and feeling a firm structure that is not floppy, the examiner must maintain vigilance and make sure that he or she is not accidentally palpating the brachialis tendon, intact bicipital aponeurosis, or palpating a partial tear of the biceps tendon.

A patient experiences a sudden-onset severe headache with nausea and vomiting while performing a heavy deadlift. He is rushed to the ED where the ED physician documents the patient with headache, neck stiffness, mild left hemiparesis, and confusion. What is the most appropriate Hunt and Hess score for this patient?

The Hunt and Hess scale for subarachnoid hemorrhages can be simplified as follows: Grade 1: roughly asymptomatic (potentially mild symptoms) with no neurologic deficits. Grade 2: Severe headache, neck stiffness are present with no major neurologic deficit or confusion. Grade 3: Headache, neck stiffness, confusion, with focal neurologic deficit. Grade 4: Extremely confused (think heavily inebriated), headache, neck stiffness, with severe focal neurologic deficit. Grade 5: coma.

What are the grades in the Hunt and Hess Scale?

The Hunt and Hess scale for subarachnoid hemorrhages can be simplified as follows: Grade 1: roughly asymptomatic (potentially mild symptoms) with no neurologic deficits. Grade 2: Severe headache, neck stiffness are present with no major neurologic deficit or confusion. Grade 3: Headache, neck stiffness, confusion, with focal neurologic deficit. Grade 4: Extremely confused (think heavily inebriated), headache, neck stiffness, with severe focal neurologic deficit. Grade 5: coma.

The lateral antebrachial cutaneous nerve (LAC) arises off of what part of the brachial plexus?

The LAC is actually just the terminal portion of the musculocutaneous nerve, after it has innervated all its muscles.

You are performing a physical exam on a patient with knee pain. You flex the hip and knee, externally rotate the ankle, and apply a valgus force to the knee while extending the knee. Which structure are you assessing for a tear?

The McMurray test is described here. It is a test for meniscus tears in the knee. By externally rotating the ankle and applying a valgus force while extending the knee, you are testing the medial meniscus for tears; internal rotation with varus force is a test for the lateral meniscus. Both are called the McMurray test. Tip: the heel itself moves toward the meniscus being tested; i.e. with external rotation, the heel moves medially, and thus, the medial meniscus is tested (with external rotation + valgus stress to the knee).

The National Pressure Ulcer Advisory Panel (NPUAP) pressure injury staging system is as follows: ●1 = nonblanchable erythema (red skin that stays red when you press on it) ●2 = skin breakdown extends into the dermis ●3 = through the dermis with subQ fat exposed ●4 = muscle, tendon, or bone is exposed ●Deep tissue injury = purple, intact skin, but the wound bed cannot be visualized ●Unstageable = really a stage 3 or 4, but you can't tell because there is so much slough/debris

Some individuals possess a normal anatomic variant by which their median nerve motor fibers in the hand cross over to join the ulnar nerve. Which of the following is the correct name for this variant?

The Riche-Cannieu anastomosis involves median motor fibers in the hand crossing over to join the ulnar nerve; classically this can cause the ulnar nerve to supply motor control to the entire hand. The Martin-Gruber anastomosis is another anatomic variant involving median nerve fibers crossing over in the forearm to innervate the ulnar nerve and supply some ulnar nerve muscles in the hand. "Kertley-Thompson anastomosis" and "Shelley-Webster anastomosis" are fictional. Perhaps Kertley and Thompson are indeed out there, searching for their anastomosis of fame.

The blink reflex study tests CN V and CN VII in the brainstem and peripherally. CN V has two nuclei being tested (Vm and Vs). The Vm nucleus lies where. Vs nucleus?

The Vm nucleus lies within the pons. It accepts CN V input from the face and conducts it to the ipsilateral CN VII nucleus, causing an ipsilateral blink (R1 response). It also simultaneously conducts the impulse to the medulla where the Vs nucleus lies. Vs accepts the impulse from Vm and sends the impulse to the bilateral CN VII nuclei, which then causes a bilateral blink via the orbicularis oculi muscles (R2 response).

The area of hypovascularity of the achilles tendon (leading to tears in this region) is generally at which of the following locations on the tendon? The musculotendonous junction Distal 2-6 cm of the tendon

The achilles tendon's zone of hypovascularity is generally within the distal 2-6 cm of the tendon, predisposing this region to tendon tears due to the poor blood supply.

The purpose of the muscles within the lateral compartment of the lower leg is to perform which of the following actions?

The fibularis longus and brevis are located within the lower leg's lateral compartment along with the superficial fibular nerve which innervates these muscles. Their action is to cause plantarflexion and eversion of the ankle.

You are seeing a 26 year-old marathon runner in follow-up. You previously prescribed physical therapy for achilles tendon pain. Since finishing the physical therapy, the patient notes minimal relief of their pain. You decide to perform a diagnostic ultrasound scan of the achilles tendon. Immediately you notice a thickened, hypoechoic appearance of the tendon. Color doppler reveals punctate pulsations of blood flow within the tendon. What is the etiology of this condition, defined by the totality of these ultrasound findings?

The findings above describe findings of tendonosis, which is a chronic degenerative process. This is typically due to poor strength and overuse of the tendon. Subsequent neurogenic inflammation can develop, as indicated by the color doppler flow. Physical therapy is a good starting treatment for this. Failing this, it is reasonable to try regenerative tendon interventions with ultrasound guidance.

The function of the anterior talofibular ligament (ATFL) is to do what?

The function of the ATFL is to resist anterior talar translation. The ATFL's integrity can be tested using the anterior drawer test of the ankle, in which the examiner stabilizes the calf distally and pulls anteriorly on the calcaneus, thus drawing the talus anteriorly, separating it away from the fibula and, thus, stretching/stressing the ATFL. If it is torn, there will be no firm endpoint. << Previous

50-year-old patient reports a headache that begins in the back of the head, radiating to the vertex of the scalp. The patient denies any other associated symptoms, including fever, neck pain, lacrimation, nausea, visual disturbance, or sensorimotor deficits. On exam, they have pain with palpation just lateral to the occipital protuberance. What is the most likely diagnosis for this case?

The greater occipital nerve is the medial branch of the dorsal ramus of the second cervical nerve (C2). It provides sensory innervation to the posterior scalp up to the vertex, among other areas. It is located lateral to the external occipital protuberance, just medial to the occipital artery, where is can be blocked with injection of local anesthetic. Tension headache is usually described as a band-like pain around the head. Migraine headache is generally described as a unilateral, severe headache, often associated with nausea, photosensitivity, and aggravated by physical activity. Cluster headache is severe unilateral orbital/supraorbital pain with may be associated with lacrimation, ptosis and nasal congestion

Which orthoses would be most appropriate in the setting of a type 2 dens fracture?

The halo vest and Minerva jacket are the appropriate orthoses for use in unstable cervical spine fractures, such as a type 2 dens fracture. The philadelphia collar is useful for stable cervical spine fractures. The Jewett brace is a thoracolumbosacral orthosis (TLSO) and not useful for cervical spine fractures.

What are the borders of guyon's canal?

The hook of the Hamate forms the lateral (radial) border of Guyon's canal, while the pisiform forms the medial border. The hypothenar muscles form the floor of Guyon's canal along with the flexor retinaculum. The ulnar nerve can become entrapped within Guyon's canal, producing an ulnar neuropathy at the wrist. A hook of the Hamate fracture can cause ulnar neuropathy at the wrist.

What is the function of the iliofemoral ligament regarding the hip?

The iliofemoral ligament extends from the ileum to femur on the anterior side of the hip joint. Its function is to limit hip abduction, extension, and external rotation.

The final ligament pierced by a spinal needle during an epidural injection is?

The ligamentum flavum is the final ligament that is pierced by an epidural needle during an epidural injection. Once piercing the ligamentum flavum, classically a "loss of resistance" is felt in the syringe, meaning that it is now much easier to inject medication through the syringe, now that the needle has entered the relatively "wide open" epidural space.

The most common cause of death in acute spinal cord injury cases is:

The most common cause of death in acute SCI is pulmonary embolism. The most common cause of death in chronic SCI is pneumonia.

What is the most common cause of mortality after total hip replacement?

The most common cause of mortality after total hip replacement is cardiovascular complications followed by thromboembolic events.

What is the most common cause of traumatic brain injury in pediatric patients?

The most common cause of overall TBIs is MVAs. The most common cause in elderly patients is falls. The most common cause in children is MVAs

In SCI patients, the most common time to onset of heterotopic ossification following injury is:

The most common onset is 1-4 months, but can be present up to the first 6 months.

Which of the following is the most common type of spinal cord injury?

The most common type of SCI is incomplete tetraplegia, followed by incomplete paraplegia, complete paraplegia, and complete tetraplegia, in that descending order, as of the most recent statistics.

The Bobath (neurodevelopmental) technique of rehabilitating a stroke patient aims to do which of the following?

The neurodevelopmental approach to rehabilitation seeks to eliminate abnormal spasticity, flexor synergy, and primitive reflexes. The Brunnstrom approach involves promoting these factors to facilitate function in ambulation and ADLs. The Rood approach involves sensory stimulation to help retrain proper movement patterns. Proprioceptive neuromuscular facilitation (PNF) involves performing diagonal movement patterns to facilitate a more natural movement for the limbs.

67-year-old male with a history of cervical spondylosis presents with right hand paresthesias. His internist orders an EMG/NCS of his right upper extremity, which reveals absent median nerve SNAP (sensory nerve action potential) and positive sharp waves in the APB (abductor pollicis brevis) muscle during the needle exam. He undergoes surgical treatment. Following surgery, which of the following orthoses is most appropriate?

The patient has right hand paresthesias in the setting of severe median neuropathy findings on EMG (absent median nerve SNAP and active denervation of APB (PSWs)) which indicates median neuropathy as the likely diagnosis. The most appropriate surgical intervention would be carpal tunnel release given the severity of the disease based on electrodiagnostic findings. Following carpal tunnel release, a gel shell splint is used; this is a nonarticular brace (doesn't cross joint meaning it doesn't restrict ROM) used to help prevent hypertrophy of the surgical scar by maintaining pressure against the healing incision. A thumb spica splint limits thumb ROM, and can be used for DeQuervain tenosynovitis, skier's thumb, dis

All of the following bones belong in the distal row of carpal bones except which of the following?

The proximal row of carpal bones contains scaphoid, lunate, triquetrum, and pisiform. The distal row of carpal bones contains trapezium, trapezoid, capitate, hamate.

The proximal row of carpal bones contains ?. The distal row of carpal bones contains?.

The proximal row of carpal bones contains scaphoid, lunate, triquetrum, and pisiform. The distal row of carpal bones contains trapezium, trapezoid, capitate, hamate.

Approximately 2 months after an ischemic stroke while in acute rehab, a patient develops shoulder pain on his hemiparetic side. He also notices some swelling in his hand, allodynia in the entire upper extremity, and increased sweating even at rest in the affected extremity. He is noted to have an IV in the same extremity. What is the likely cause of this patient's symptoms.

The question stem gives a history and physical signs concerning for CRPS type I, formerly known as reflex sympathetic dystrophy. It is often characterized by sympathetic-mediated pain, sensory abnormalities, allodynia, abnormal blood flow, and trophic changes. If an identifiable peripheral nerve injury occurs preceding signs/symptoms, CRPS type II also known as causalgia is the likely culprit. Superficial thrombophlebitis and acute DVT, although reasonable to put on a differential diagnosis for the above case, are ultimately meant to be distractors in this question.

During a blink reflex study, when stimulating the left trigeminal nerve, you detect a single left eye blink response. This is known as which of the following?

The quick, ipsilateral blink response is called the R1 response, and we record it from the orbicularis oculi muscle ipsilaterally to the side of stimulation.

The "roof" of the tarsal tunnel is also known as which of the following?

The roof of the tarsal tunnel can be thought of as the flexor retinaculum, under which the structures of the tarsal tunnel pass.

Which of the following is the primary structure that maintains the humeral head within the glenoid fossa?

The rotator cuff is chiefly what maintains proper contact of the humeral head within the glenoid fossa. When these muscles are weak (e.g. stroke) the humeral head is far more likely to sublux out of the glenoid fossa. The other structures listed are secondary to the rotator cuff in this role.

The strenuousness of an activity relative to basal metabolic rate is defined as which of the following?

The strenuousness of an activity relative to basal metabolic rate is defined as how many metabolic equivalents (METs) the activity is above basal metabolic rate. For example, lying flat is 1 MET, and walking on a treadmill is 3 METs (roughly).

You are reviewing left lower limb EMG/NCS findings and trying to propose a possible treatment plan to the patient. The patient is experiencing foot pain not relieved by NSAIDs or heat/ice. NCS reveals normal superficial fibular and sural SNAPs (sensory nerve action potentials), prolonged latency of medial and lateral plantar nerve SNAPs, and abnormal CMAP (compound muscle action potential) to abductor hallucis (AH). The CMAP to the extensor digitorum brevis (EDB) is normal. Needle EMG reveals decreased recruitment in AH, abductor digiti quinti pedis (ADQP), and lumbricals. EMG of tibialis anterior, EDB, gastrocnemius, fibularis longus, hamstrings, rectus femoris, tensor fascia lata, and lumbosacral paraspinals is normal. Which of the following is the most reasonable treatment strategy for this condition?

These findings suggest tarsal tunnel syndrome, a rare compression of the tibial nerve as it passes through the tarsal tunnel around the medial malleolus, underneath the flexor retinaculum. The flexor retinaculum is a common culprit that compresses the tibial nerve too tightly, causing the patient's symptoms of plantar foot pain with numbness/tingling and possible foot muscle weakness. Surgical release of the flexor retinaculum (akin to carpal tunnel release) is the best option of these choices (a structural solution for a structural problem). US-guided tarsal tunnel injection could also be considered. Bracing would not do anything to decompress the tarsal tunnel. Gabapentin also would not decompress the tarsal tunnel, but mask the symptoms while the nerve compression continues, potentially destroying axons over time. Peripheral nerve stimulation is not appropriate for this reason also.

A 21 year-old female complains of gradual onset worsening right hip pain. She is currently training for a marathon. She denies weakness, numbness, and tingling. X-rays reveal a cortical lucency along the inferior/medial femoral neck. There is pain during normal ambulation. What is the most appropriate next step in management?

This patient has developed a compression-side proximal femur stress factor. Risk factors include low BMI, poor nutrition, amenorrhea, osteoporosis. Compression-side fractures (on inferior/medial side of femoral neck) are more common than tension-side fractures (fractures along superior/lateral femoral neck) and can be treated with non-weight-bearing for a period of time, then gradual weight-bearing as tolerated, then gradually increase activity. Tension-side fractures are less stable and require orthopedic surgery consult for ORIF.

A 65 year-old female is brought to the ED due to sudden-onset right hemiplegia. On exam you discover she has impaired sensation to light touch on her right side. Her extraocular motility and visual acuity are normal bilaterally. When asked to stick out her tongue, her tongue deviates toward the left side. What is the most likely diagnosis?

This patient has suffered a stroke of her left medial medulla. In the medial medulla lies the corticospinal tract, medial lemniscus, and CN 12 nucleus. Thus, damage to these structures will cause, respectively, contralateral hemiparesis/plegia, contralateral impaired light touch, and ipsilateral CN 12 palsy (tongue deviates toward the side of the lesion). Weber syndrome presents with contralateral hemiparesis with ipsilateral CN 3 palsy.

A 27-year-old manual laborer presents with a 6-month history of right shoulder pain. He has a past medical history of a traumatic right shoulder dislocation 3 years ago. On physical exam, he has normal strength and sensation with symmetric reflexes. The shoulder apprehension test is positive. Impingement tests and the O'Brien active compression test are negative. What type of labral tear is most consistent with this presentation?

This patient presents with an anterior-inferior labrum tear related to chronic unidirectional anterior shoulder instability following a prior traumatic event (dislocation). This type of instability is common after a traumatic event as opposed to multidirectional instability, which is associated with congenital laxity or chronic repetitive microtrauma. Anatomically, unidirectional anterior instability involves disruption in the anterior-inferior glenohumeral joint capsule and anterior-inferior labrum with or without associated bony injury to the glenoid rim (Bankhart lesion) and humeral head (Hill-Sachs deformity). Superior labral anterior to posterior (SLAP) lesions may occur, but that possibility is less likely in this patient, because of his history and a negative O'Brien compression test.

55 year-old female presents to your clinic with the complaint of fever and elbow problems. She notes that for the past several weeks she has noticed her right elbow is "bigger" than the left elbow. She is a student and has been taking lots of college classes lately. She uses an elbow pad to no benefit. On exam, strength and sensation are intact. You notice that at the posterior elbow there is a very large swelling. It is compressible and warm. The patient notes some discomfort there and asks you to "do something". What is the next best step?

This patient presents with classic findings of olecranon bursitis, which is usually due to repetitive forces to the olecranon, such as grinding your elbow on a desk for several hours daily (art, desk work, etc.). A large pouch of fluid develops at the olecranon bursa because there is very little skin there to prevent it from expanding if it is inflamed. Treatment involves RICE, elbow pad, and considering aspiration. It is not usually an infectious process, but if the patient has a fever, then consider aspiration, culture, and antibiotics. This patient has failed conservative treatment, and aspiration of this bursa carries little risk if done properly. Caution the patient that there is a good chance it will recur following aspiration unless the irritant forces are removed that are causing the bursopathy in the first place.

A 47 year-old male presents with 3 weeks of nonpainful left elbow swelling. He denies numbness, tingling, weakness, fever, chills, or trauma. He is an architect and draws blueprints for buildings as part of his work. He is bothered by the cosmetic appearance of the swelling. On exam, you note a posterior elbow fluctuant mass which is nontender to palpation; there is no rash. Neurologic examination is normal in the upper extremities. You trial an elbow pad; he returns 1 month later stating that the swelling is unchanged. Which of the following is the next best step in management?

This patient presents with classic olecranon bursitis. This is a commonly nonpainful outpouching of fluid due to irritation/bursitis of the olecranon bursa in the posterior elbow, which lies just deep to the skin over the olecranon. Olecranon bursitis is more likely in individuals who lean on their elbows or otherwise experience frequent friction/compressive forces to their posterior elbow. Treatment involves elbow padding as conservative care; if this fails, olecranon bursa aspiration is likely indicated. Corticosteroid injection is not warranted in the bursa, as injection of this superficial bursa with corticosteroid will increase the risk of infection without added clinical benefit compared to aspiration alone. Orthopedic surgery referral is indicated in recalcitrant cases failing aspiration. There is little to no clinical suspicion of an infected bursa in this patient, thus empiric antibiotics alone are not warranted.

A 52 year-old male presents with 3 weeks of anterior right knee pain and swelling. On examination you detect a bulbous, soft, fluid-filled pouch just anterior to the patient's patella, which is tender to palpation. The patient denies fever, chills, rash, or tick exposure. He works in home construction and spends a lot of his time on his hands and knees installing flooring. Strength, sensation, and reflexes are intact in both lower extremities. He asks you to do something today for him, because his pain is unbearable. Which of the following is the most appropriate next step?

This patient presents with classic prepatellar bursitis, the fluid-filled distension of the prepatellar bursa just anterior to the knee cap (patella). This is most often irritated with prolonged anterior knee friction/compressive forces (e.g. prolonged kneeling). Prepatellar bursitis can be painful. Knee pads are a useful conservative treatment for this problem in patients who are willing to trial conservative care alone. This patient requests urgent treatment today; thus, aspiration of the prepatellar bursa is warranted. Corticosteroid injection is not appropriate into this superficial bursa, as this will increase the risk of infection without added clinical benefit. Orthopedic surgery referral for bursectomy is not indicated except in intractable cases.

64 year-old female presents to your clinic with complaints of 2 months of sciatica. She notes burning left buttock pain radiating down her posterior left thigh, stopping at the knee. Her pain is often relieved with shifting her weight onto her right buttock when sitting. She notes some tingling in her left buttock. She denies bowel or bladder dysfunction, and denies saddle anesthesia. On exam she has 5/5 strength in the left lower limb, intact sensation, and normal reflexes. Left slump sit causes left posterior thigh pain. There is tenderness to palpation of the left proximal medial buttock. There is left buttock pain with resisted knee flexion. What is the most likely diagnosis?

This patient presents with classic symptoms of ischial bursitis. The ischial bursa lies between the ischial tuberosity (your "sit" bone on both sides) and the gluteus maximus muscle. It can be inflamed in some patients, causing pain described here, worse with palpation of the ischial bursa (as noted on exam here), and worse with sitting (relieved with shifting weight onto the normal buttock, thus relieving pressure off the inflamed bursa). The ischial tuberosity is also the origin of the hamstrings, and realistically hamstring strains or tendonitis is more likely than ischial bursopathy, but both present very similarly to this patient. Piriformis syndrome would cause lateral buttock pain closer towards the greater trochanter. Greater trochanteric pain would be lateral on the proximal thigh, and SI joint dysfunction would cause a low back pain with positive SI joint tests, none of which were performed in this patient. Treatment of ischial bursitis involves rest, ice, NSAIDs, PT, corticosteroid injection into the bursa.

A 42 year-old female is evaluated in your inpatient rehabilitation unit. Therapists are concerned that her tremors are interfering with her functional progress. On examination, you notice no tremor at rest, but when you ask her to point to different pictures on a board in front of her, her aim is poor and she often misses her target, overshooting and undershooting it. The therapists have tried wrist weights, and these have not benefited her. What is the next best step for treating her tremor?

This patient presents with tremor during coordination of limbs, notably with attempting to accurately point to a spot in space, and demonstrating dysmetria in the process. This is known as an intention tremor and is associated with cerebellar dysfunction. Failing conservative therapy, oral medications should be initiated to treat intention tremor. Clonazepam has been shown in the literature to be effective for cases of intention tremor.

62 year-old male presents with 1 year of gradual onset low back pain radiating into bilateral posterior thighs, associated with stable bilateral lower extremity paresthesias and weakness. He feels like the longer distances he walks, the heavier his legs become. He denies bowel or bladder changes. On exam he has 3+/5 extensor hallucis longus (EHL) and gastrocnemius strength bilaterally; the remainder of his strength is intact. What is the next best step?

This patient suffers from lumbar spinal stenosis. This is a narrowing of the central spinal canal that leads to compression of the neural structures within; the narrowing is typically due to degenerative spondylosis. The symptoms can be described as neurogenic claudication: leg pain, weakness, leg heaviness with activity, especially those which involve spinal extension, such as standing upright, and walking downhill. Symptoms are typically relieved by spinal flexion, e.g. leaning forward on a shopping cart. Weakness may be demonstrated on exam. The important point to know is that true neurologic weakness by itself (as in this case) does not require emergency spine surgery. This patient has had chronic, unchanged weakness that is not progressing; thus, physical therapy is the most appropriate initial intervention. Acute weakness (e.g. acute, sudden foot drop) requires a stat surgical consult. Lumbar stenosis is best treated with physical therapy and trial of oral medications such as gabapentin. Failing this, MRI of lumbar spine and neurosurgery consult would be indicated, vs. trial of epidural steroid injection (the evidence is mixed for epidural injections in lumbar spinal stenosis).

Tizanidine's mechanism of action

Tizanidine stimulates alpha-2 receptors; this stimulation then inhibits the spinal reflex arc, and is useful for treating spasticity.

A patient presents to your office with neck pain radiating into his right arm and hand in a C6 dermatome distribution. He has no neurologic deficits. He would like to trial physical therapy prior to imaging or more aggressive treatment options, which you agree is appropriate. You write a prescription for physical therapy and would like to trial cervical traction to help alleviate any nerve root compression. He does not have any contraindications to cervical traction. Which of the below parameters are most appropriate for symptomatic relief during cervical traction?

To best relieve cervical nerve root compression, 20-30 degrees of cervical flexion is the optimal angle to open the neuroforamina. For the cervical spine, distraction forces of >25 lbs are optimal, but forces beyond 50 lbs provide no further improvement. For the lumbar spine, >50 lbs of traction force is indicated

5 year old boy presents with right knee pain. and a limp. He has no hx of trauma. Physcial examination is remarkable for an abducted and externally roated righ thip. He has significant pain with internal rotation. What is the most likely cause of this boys symptoms.

Transient synovitis most commonly in boys between 3 and 8. Children typically have symptoms for one to 3 days and present with an antalgic gait and an abducted and externally rotated hip at rest. Pain is exacerbated with internal rotation of the hip although pain with motion is less severe than children with septic arthritis. treat with rest nad NSAIDS

6 year old with fracture of the physis, metaphysis. what Salter Harris is this?

Type 2

Which muscle fiber type uses only glycolytic metabolism for energy?

Type 2 B There are 2 primary muscle fiber types in humans. They are categorized according to speed of contraction and sources of fuel. Type 1 muscle fibers are slow-twitch with oxidative metabolic pathways. Type 2 muscle fibers are fast-twitch fibers. The type 2 fibers can then be further divided into fast-twitch with both oxidative and glycolytic metabolism (type 2a) and fast-twitch glycolytic (type 2b).

During a blink reflex study, you recall that the Vs nucleus is located within which of the following structures?

V s is in medulla The blink reflex study tests CN V and CN VII in the brainstem and peripherally. CN V has two nuclei being tested (Vm and Vs). The Vm nucleus lies within the pons. It accepts CN V input from the face and conducts it to the ipsilateral CN VII nucleus, causing an ipsilateral blink (R1 response). It also simultaneously conducts the impulse to the medulla where the Vs nucleus lies. Vs accepts the impulse from Vm and sends the impulse to the bilateral CN VII nuclei, which then causes a bilateral blink via the orbicularis oculi muscles (R2 response).

When do vertebral compression fractures need surgery?

Vertebral body compression fractures typically occur at the thoracolumbar junction, as in this case. They are typically due to trauma, and osteoporosis is sometimes a contributing factor. Spine surgery is required if the spine is unstable (middle column damage, or any 2 columns being damaged), there is > 50% loss of vertebral body height, or there are neurologic deficits as a result of the vertebral body fracture

You are performing pre-participation physical examinations on a high school lacrosse player. Vitals signs reveal a blood pressure of 149/81, heart rate of 92, and respiratory rate of 16. Visual acuity is 20/60 on the right 20/80 on the left. Past medical history is significant for two previous concussions without residual symptoms. Medical examination reveals an I/VI systolic ejection murmur that is eliminated with Valsalva, which has been previously evaluated. Musculoskeletal examination is significant for left shoulder pain with empty can testing. Which finding will prevent immediate clearance of this student-athlete to participate in lacrosse?

Vision According to the most recent pre-participation guidelines, an innocent murmur does not indicate heart disease and full participation is permitted. Prior concussions, while concerning, do not warrant restriction if the patient is asymptomatic and has been previously evaluated. A weakened rotator cuff, while worthy of a follow-up examination, does not warrant restriction from competition. Eye sight that is less than 20/40, especially in athletes where depth perception and a moving ball is part of the sport (such as in lacrosse), requires further evaluation prior to clearance

A 68 year-old male is hospitalized for sudden-onset left hemiparesis. On exam you notice his right eye appears to be looking down and to the right. His sensation and coordination are otherwise intact. What is the most likely diagnosis?

Weber (medial midbrain) syndrome is caused by an interruption of the medial midbrain's blood supply (typically from the ipsilateral posterior cerebral artery - PCA), leading to paralysis of the medially located corticospinal tract fibers, which will cause a contralateral hemiparesis, as these fibers have yet to decussate (cross) in the medulla more inferiorly. As we are in the midbrain, medially we have the CN 3 nucleus, thus causing an ipsilateral CN 3 palsy.

What is required to obtain a driver's license for an individual with cerebral palsy?

complete a driving eval Driving allows individuals with cerebral palsy increased freedom in their surroundings. The clinician may be asked to assess whether a particular individual is medically fit to drive. Because driving requires multiple factors to work in tandem for success, a complete evaluation is needed. The individual requires adequate strength, speed and coordination of either the upper or lower extremities. Cognitive skills such as concentration, attention, visual perceptual skills, and memory will play a role. The ability to process multiple pieces of information simultaneously and make a quick, safe decision is required. It is helpful to have an adaptive vehicle, but that is not necessary to get a driver's license. It is important for seizures to be well controlled and the requirements vary from state to state (from 3-12 months seizure-free) on when a person with seizures can drive, but being off all antiepileptic medication is not required in most states. There are no federal requirements, only state Motor Vehicle Administration requirements.

Which of the following would typically be found in the transfemoral prosthesis of a 7-month-old amputee?

no knee component Pediatric amputees are prescribed a prosthesis when they are at least 6 months old, and are starting to pull themselves to stand (fit to stand), in keeping with the timeline for developmental milestones. For a child learning their initial balance and ambulation, a simple and stable prosthesis is best. Progressing proximally to distally, the transfemoral prosthesis would have a solid ankle foot and no knee joint, since children cannot control the movement in an articulated knee until the age of three years, and an articulated foot will make balance difficult to learn and increase fall risk. The transfemoral socket is placed in abduction to match the increased hip abduction and external rotation found in children of this age. A total elastic suspension (TES) belt is the simplest for parents to learn, and is more easily adjustable as the child grows, and allows for (relatively) greater ease during diaper changes.

A 27-year-old golfer presents with pain on the volar ulnar aspect of his hand. X-ray shows he has a fracture of the hook of his hamate bone. What is the treatment of choice?

ortho referral Hamate hook fractures represent 2-4% of all carpal fractures and are a common injury in golf, baseball and hockey. Patients usually present with vague complaints of pain at the volar ulnar aspect of their hand with pain provoked when attempting a tight grip. Plain radiographs may not visualize the fracture thus a CT scan should be considered if one has a high suspicion for fracture. Excision of the hook of the hamate is considered the treatment of choice. Acute injuries and non-displaced fractures may be treated non-operatively but excision is the treatment of choice. Nonunion rates greater than 50% and as high as 80-90% can occur with conservative treatment. Therefore, all hamate hook fractures should be referred to a hand surgeon for possible surgical intervention.

What is the most common type of voiding dysfunction among elderly individuals?

overactivebladder Overactive bladder, also referred to as detrusor overactivity, is the most common type of voiding dysfunction among incontinent elderly individuals. Outlet obstruction (caused by prostatic hypertrophy) is the 2nd most common cause of incontinence among elderly male individuals, while stress incontinence is the second most common cause of incontinence among elderly females. Detrusor underactivity is much less common, but may contribute to overflow incontinence in this age group.

What is the leading cause of death for individuals with subacute or chronic traumatic spinal cord injury?

pneumonia Data from the National Spinal Cord Injury Statistical Center Database demonstrate that the leading cause of death following traumatic spinal cord injury (SCI) is non-circulatory respiratory disease, with the large majority representing deaths due to pneumonia. Heart disease is the second leading cause of death, followed by septicemia and other infective diseases. Pulmonary embolism is one of the leading causes of death in the first month after injury, but only the 5th leading cause of death in subacute or chronic SCI.

Which of the following is the most frequent association of nerve injury and fracture?

radial nerve and humeral fracture Radial nerve injury with humeral fracture is the most frequent association of nerve injury and fracture. Radial neuropathy occurs in 11% of humeral fractures, but up to 60% of midshaft frac-tures. Especially in multi-trauma scenarios, peripheral nerve injury may not be identified on initial evaluation.

13-year-old right hand dominant baseball pitcher is seen in your clinic with right lateral shoulder pain that is aggravated by throwing. He denies any prior shoulder injury. Your examination is significant only for tenderness along the lateral deltoid. Radiographs of right shoulder are normal. The next best step in management of this patient is:

radiograph the left shoulder This adolescent has the hallmark history and potential signs of Little League Shoulder (LLS)/Glenohumeral Epiphysiolysis. LLS is a repetitive stress injury due to overuse and improper rest that typically occurs in young teenagers. It is likely a result of torsional overload of the proximal humeral epiphysis during maximal shoulder external rotation during the throwing cycle. In order to fully compare the physes, contra-lateral radiographs are needed as even subtle differences can make the diagnosis. MRI imaging not as efficient and more expensive. Treatment recommendations include elimination of throwing for 6 weeks after diagnosis and an additional 6 weeks of rehabilitation without throwing. A return to throw/pitch program is initiated once the patient is pain free and has completed a rehabilitation program without setbacks.

What is the primary disadvantage of moving the rear axle of a wheelchair forward?

ramps can be difficult Moving a wheelchair's rear axle forward enables the user to propel the chair with less muscle effort and fewer strokes. Because the modification causes more weight to be centered over the rear wheels, it is easier to pop a wheelie, negotiate obstacles and ascend or descend curbs. However, moving the axle forward can also make the wheelchair more likely to tip backwards thus making it more difficult to propel the chair up a ramp.

Which of the following may develop from exposure to cisplatin?

sensory impairment Cisplatin is a neurotoxic chemotherapeutic agent used in a variety of cancer types. Its putative mechanism of action with respect to neuropathy is disruption of cellular functions at the dorsal root ganglion and subsequent death or dysfunction of the sensory nerves. Since platinum analogues do not usually cross the blood-brain barrier at contemporary doses, the anterior horn motor cells are unaffected. Abnormal sensations (paresthesias), painful sensations (dysesthesias), loss of sensation (anesthesia), and other neuropathic sensory disorders are common, but weakness is not generally seen. Gait dysfunction and ataxia is from sensory dysfunction and not muscle weakness.

In evaluating a patient with pain, you decide to squeeze her left tibia together by wrapping your hands around the medial and lateral borders of the tibia and squeezing. The purpose of this test is to diagnose which of the following conditions?

shin splints Squeezing the tibia and reproducing a patient's pain is indicative of shin splints (medial tibial stress syndrome). One may also perform a squeeze test to examine a high ankle sprain, but x-rays would be the best test for Maisonneuve fracture (a complication of a high ankle sprain), not physical exam.

A 21-year-old basketball player attempts to catch a pass from his teammate but drops the ball and immediately experiences pain in his distal third digit. Instant replay shows the basketball hitting his third fingertip causing a forced flexion moment at the DIP. He is taken out of the game and seen by the team physician; during initial examination, the patient is unable to actively extend the DIP of his third finger. Xrays are negative for acute fracture. What splint is most appropriate to promote proper healing of his injury?

stax splint The vignette describes a mallet finger injury, which is often seen in sports such as basketball or baseball. Typically, a ball hits the distal aspect of a finger, causing flexion of the DIP and resultant extensor tendon rupture. This leads to inability to actively extend the DIP. X-rays are appropriate to rule out avulsion fracture. A stax splint or DIP extension splint is appropriate to allow for healing of the DIP extensor tendon. A swan-neck ring splint and Boutonniere ring splint are examples of static-motion blocking splints that are used to treat their respective namesake. A resting hand splint promotes ROM of joints of the hand to avoid contracture formation, typically after stroke.

You are reviewing left lower limb EMG/NCS findings and trying to propose a possible treatment plan to the patient. The patient is experiencing foot pain not relieved by NSAIDs or heat/ice. NCS reveals normal superficial fibular and sural SNAPs (sensory nerve action potentials), prolonged latency of medial and lateral plantar nerve SNAPs, and abnormal CMAP (compound muscle action potential) to abductor hallucis (AH). The CMAP to the extensor digitorum brevis (EDB) is normal. Needle EMG reveals decreased recruitment in AH, abductor digiti quinti pedis (ADQP), and lumbricals. EMG of tibialis anterior, EDB, gastrocnemius, fibularis longus, hamstrings, rectus femoris, tensor fascia lata, and lumbosacral paraspinals is normal. Which of the following is the most reasonable treatment strategy for this condition?

surgery These findings suggest tarsal tunnel syndrome, a rare compression of the tibial nerve as it passes through the tarsal tunnel around the medial malleolus, underneath the flexor retinaculum. The flexor retinaculum is a common culprit that compresses the tibial nerve too tightly, causing the patient's symptoms of plantar foot pain with numbness/tingling and possible foot muscle weakness. Surgical release of the flexor retinaculum (akin to carpal tunnel release) is the best option of these choices (a structural solution for a structural problem). US-guided tarsal tunnel injection could also be considered. Bracing would not do anything to decompress the tarsal tunnel. Gabapentin also would not decompress the tarsal tunnel, but mask the symptoms while the nerve compression continues, potentially destroying axons over time. Peripheral nerve stimulation is not appropriate for this reason also.p on

In which of the following cases is microwave diathermy most appropriate?

to hasten the breakdown of a hematoma Ultrasound uses ~1 MHz sound waves to produce vibrations below the skin and produce images out of those vibrations and sound wave reflections; it is most useful to heat deep tendons, ligaments, and for general MSK pain (up to 8cm below the skin). Short wave diathermy uses radio waves ~27 MHz to heat up tissues up to 5cm deep. Microwave diathermy uses microwaves ~1000 MHz to heat very superficial structures 1-3 cm deep, and is indicated to hasten the breakdown of hematomas. Diathermy is contraindicated over metal and cancer especially, while ultrasound is not appropriate near electrical implants or cancer.

The type of muscle fiber that purely utilizes glycolysis, not aerobic respiration, for energy is:

type 2 b Type I muscle fibers are slow twitch, "red" fibers that utilize oxidative phosphorylation as part of aerobic respiration. These are the muscles primarily utilized in cardiovascular endurance exercises such as running a marathon. Type IIa fibers are fast twitch, "white" muscle fibers that are anaerobic and utilize glycolysis primarily for energy. Type IIa fibers also do have some degree of aerobic capacity. Type IIb fibers are purely glycolytic and have no aerobic capacity; these are used chiefly in powerful fast twitch activities, such as sprinting or powerlifting.

Which modality most effectively treats the periarticular tissue of the hip joint?

You are called to the bedside on PM&R consult service rounds to examine a brain injury patient. The patient exhibits open eyes. He follows no commands. He does appear to maintain sleep-wake cycles on EEG. When you pinch his arm, he flexes his elbow. How would you define this patient's arousal status?

vegetative In short, coma is defined as closed eyes, no sleep/wake cycles on EEG, and no purposeful behavior or comprehension. In vegetative state, the patient does have sleep/wake cycles on EEG, and eyes are open, but there is no purposeful activity, only reflexive actions. Minimally conscious state is defined as open eyes, presence of sleep-wake cycles on EEG, and inconsistent awareness of the environment with purposeful behaviors. When this becomes consistent, the patient is said to have "emerged" and is considered to exhibit "normal" arousal at that point, or to at least not possess a disorder of consciousness (DOC).

A 28-year-old female runner presents to you with increasing right foot pain. She recently read an article about barefoot running and so has transitioned to that over the last month. She runs six days a week, but more recently she has had to stop running due to pain and has pain throughout the day, worsened by any weight bearing. On exam, there is no swelling or redness. She has tenderness directly over the 3rd metatarsal. No tenderness elsewhere within the foot. Normal neurological exam. Pain with attempts to hop. For your initial management, you decide to:

walking boot for 3 weeks Her history indicates that she has undergone an abrupt change in her training (barefoot running) that would cause a significant change in the types of forces experienced by her skeletal system, and has an accompanying point of focal bony tenderness. Given this history and exam, the patient likely has a 3rd metatarsal stress fracture. This is not considered a "critical" stress fracture site and can be treated initially with a walking boot. If she is able to walk without limping in 3 weeks, she can be progressed out of the boot and to physical therapy. Non-weight bearing in a cast for 6 weeks is generally not needed with "non-critical" stress fractures and would be overly restrictive. Radiographs are relatively insensitive for stress fractures, and would not likely change management in this case as there is little concern for a "critical" stress fracture. Given her likely injury, pain, and functional limitations, returning her to activities at this time would be inappropriate.

How should a PM&R physician define ephaptic transmission?

way of firing a motor unit that has undergone a denervation-reinnervation-denervation cycle A CRD (complex repetitive discharge) is an involuntary discharge that is very wide and serrated (complex in appearance, and repetitive in firing) and occurs due to a motor unit being denervated and then reinnervated by another motor neuron, which itself then becomes denervated. Ephaptic transmission is the process by which these muscle fibers all fire regularly together. CRDs are seen in chronic radiculopathy, anterior horn cell disease, and some normal patients.

Which stroke syndrome has ipsilateral ptosis, external strabismus, a dilated pupil, and contralateral weakness of the lower face, tongue, arm, and leg?

What are the characteristics of cervical facet (zygapophyseal) joint mediated pain?

whiplash injury Facet joint (zygapophyseal) pain is frequent in individuals with chronic cervical pain following whiplash injuries. Localizing neck pain to the facet joints can be difficult because facet joint pain referral patterns can overlap discogenic or myofascial pain patterns. Facet joint pain may be difficult to reproduce with palpation and is more common with cervical extension rather than cervical flexion. The referral pattern is typically to the neck and shoulders.
