AA 2 quizzes

Which of the following tasks best demonstrates that the pt. has normal functional quadriceps strength?

Performing a sit to stand without any forward trunk lean

Your patient complains of pain in their knee on the medial side. They said the symptoms started after being tackles in a soccer game. When examining their knee you move the knee into slight flexion and then apply a lateral to medial force with the palm of your hand that is directed at the knee joint which reproduces their knee pain. What structures might be injured?

Medial collateral ligament of the knee

The normal end-feel for knee extension is

firm because of the, tension in the posterior joint capsule; the collateral ligaments, ACL, PCL, as well as the oblique and arcuate popliteal ligaments

According to AAOS normative value, the amount of ankle inversion is:

35 degrees

Which of the following would be most correct way to document for a patient who has 135 degrees of knee flexion and 5 degrees of hyperextension of the knee?

5-0-135

Which ligament of the ankle is most tensioned through passive inversion with the ankle in neutral?

Calcaneofibular (B/C OF NEUTRAL ALIGNMENT)

This thin, string or cable-like structure can be palpated in the popliteal fossa, just medial to the biceps femoris tendon as well as just distal and posterior to the fibular head:

Common peroneal nerve

When performing the Thomas test, if the patient has a very tight TFL, then pushing the hip into extension would cause the patient's knee to respond with

EXTENSION

Dermatomes are in the exact same location for everyone with well-defined boundaries

False (B/c we all ain't the same; especially if you had surgery over in your thoracic, you may be feeling that sensation at S1 level)

When measuring ankle dorsiflexion ROM with goniometer, the therapist must keep the distal (moving) arm directly on the lateral aspect of the 5th metatarsal at all times

False=we want this to be parallel to the 5th metatarsal

What is the correct position to bias the medial hamstrings (Semitendinosus and Semimembranosus muscles) in an MMT?

Flexion of the knee at 45 degrees (b/w 50-70 deg, with thigh internally rotation and tibia internally rotated on the femur

1. The dorsal web-space between tosies 1 and 2 corresponds to which dermatome

L5= YEAH WE GET THIS DEEP FIBULAR NERVE BRO; also over slight dorsum aspect of foot

A pulse for dorsalis pedis artery can be palpated where?

Laterally to the extensor hallucis longus tendon or medially to the extensor digitorum longus tendon

What is considered to be the normal range for the popliteal angle (90/90) test for the hamstrings?

Less than 20 or more than 160 (both A and B are Correct); technically the appropriate range is 20-25 or 155-160

According to the Daniel's and Worthingham's Muscle Testing test, the peroneus longus muscle is tested when the therapist applies resistance against:

Plantarflexion with eversion

1. Having the patient demonstrate walking on their toes in the clinic could be a functional test for which myotome?

S1=initiates plantarflexion from lateral/posterior aspect of foot

Which of the following best describes dermatome testing?

The area of skin mainly supplied by sensory neurons of a specific nerve root

When performing an MMT for a pt. quadriceps muscle, you notice that during the test they lean back and their thigh medially rotates. What can you conclude from this compensation pattern?

The patient has weakness in their quadriceps and is trying to substitute with the TFL muscle

When performing the Ely Test for the quadriceps differ from the PROM measurement of knee flexion?

The patient is positioned in prone in order to allow the hip to be extended

At the ankle there are three tendons that run over the dorsal aspect of the foot. The most MEDIAL of these tendons is:

Tibialis Anterior

Pressure applied against the medial, dorsal surface of the foot in the direction of plantarflexion and eversion of the foot, while stabilizing at the lower leg, describes an appropriate test for which muscle?

Tibialis anterior

Which answer lists the correct order for the tendons of the muscles of the deep posterior compartment of the leg going from anterior to posterior?

Tibialis posterior, Flexor Digitorum Longus, Flexor hallucis longus

1. What is the main purpose for performing a quick neurological screen of dermatomes, myotomes, and reflexes?

To help identify patterns of symptoms or dysfunction which may indicate the need for further examination or testing

The axis of rotation of the ankle is not true medial-lateral, but more oblique. However, we measure ankle dorsiflexion and plantar flexion in the sagittal plane

True

A patient complains of having trouble moving her left foot. She has 15 deg AROM dorsiflexion on the right and 4 deg AROM dorsiflexion on the left. She has 20 deg PROM with a first end-feel bilaterally and no pain on testing. Based on the information that patient likely has:

Weakness of tibialis anterior
