AT Test 3: Shoulder
The most important and most commonly injured bursa around the shoulder joint is the:
subacromial bursa
The drop arm test is used to determine injury to what muscle?
supraspinatus
The greatest number of upper humeral fractures occurs at the:
surgical neck
In which phase of the throwing motion are the external rotators of the rotator cuff contracting eccentrically?
deceleration
Which of the following muscles is not a part of the rotator cuff?
deltoid
A positive O'Brien's Test is indicative of a full thickness tear of the supraspinatus muscle.
false
A tear or detachment of the fibrocartilage labrum on the posterior lateral aspect of the humeral head is called a "Bankhart lesion."
false
An athlete with a fractured clavicle will usually hang the arm at his or her side, internally rotated to relieve the stress on the supporting structures.
false
Biceps brachii ruptures occur mainly in football linemen who use their arms to block their opponents.
false
In scapulohumeral rhythm, the setting phase occurs when the humerus finds its position in the glenoid, while the scapula rotates during the first 30 degrees of motion.
false
The acromioclavicular joint is a strong joint reinforced by several key ligaments.
false
The frozen shoulder is a condition typically seen in younger athletes.
false
The rotator cuff muscle most commonly injured is the infraspinatus.
false
To test for bicipital tendinitis and subluxation, have the athlete flex the elbow at 90 degrees and internally rotate against resistance from the athletic trainer, as the humerus is also pulled downward.
false
If an athlete comes off the field supporting his/her injured arm, with their head tilted towards the injured shoulder and their chin turned towards the opposite side. Which injury have they likely sustained?
fractured clavice
The scapula fossa that articulates with the humerus is deepened by an additional structure called the:
glenoid labrum
Which of the following tests does NOT indicate that the subclavian artery is being compressed?
impingement syndrome test
Winging of only one scapula indicates an injury to what nerve?
long thoracic
Which of the following ligaments is responsible for restraint during flexion and external rotation of the shoulder?
middle glenohumeral
Peripheral nerve injuries can cause muscle weakness. An injury to which nerve would cause weakness in the biceps and coracobrachialis muscles?
musculocutaneous
A major criterion for the athlete's return to sports competition following a posterior dislocation is that internal and external rotation strength be equal to of their body weight.
20%
What are contusions to the distal end of the clavicle called?
shoulder pointers
Which of the following is NOT a test for glenohumeral instability?
Allen test
With an anterior glenohumeral dislocation, the athlete's the arm will be in:
slight abduction and external rotation
The brachial plexus is derived from what spinal nerve segments?
C5-T1
During which phase of rehabilitation for shoulder impingement should the athlete concentrate on strengthening the rotator cuff and limiting overhead activities?
repair phase
Which of the following tests assesses for impingement syndrome?
Hawkins-Kennedy test
In a rotator cuff injury, the stage that has shoulder pain on activity, increased pain at night, and a muscle deficit of 1 cm or less is classified as:
Stage III
Which of the following can be used to treat thoracic outlet syndrome?
all of the above
The most commmon shoulder direction for the shoulder to displace is in the _______________ direction.
anterior
Which of the following activities is likely to create chronic posterior instability in the shoulder?
backstroke swimming
In which phase of the throwing motion is maximum external rotation achieved?
cocking
A conservative method of treating subluxations and recurrent dislocations consists of strengthening muscles that act on the scapula.
true
An acromioclavicular sprain is most often induced by a direct blow to the tip of the shoulder, pushing the acromion process downward.
true
Anterior instabilities account for 95% of all chronic instabilities of the glenohumeral joint.
true
In the presence of a neurovascular injury, skin temperatures should be assessed on the back of the athlete's hand to detect alterations from the normal standards.
true
Most direct causes of anterior glenohumeral dislocations are situations in which the arm is forced into abduction and externally rotated.
true
Physicians generally agree that a first-time dislocation may be associated with a fracture, and therefore its treatment is beyond the scope of a coach's or athletic trainer's duties.
true
Postural malalignment such as forward head, rounded shoulders, and an increased kyphotic curve causes a decrease in the space under the coracoacromial arch and therefore can lead to the development of impingement.
true
Tenosynovitis of the long head of the biceps muscle is common among athletes who execute a throwing movement as part of their event.
true
The point at which the clavicle changes shape and contour presents a structural weakness, and the largest number of fractures to the bone occurs at this point.
true
Thoracic outlet compression syndrome is often attributed to a cervical rib anomaly, originating from a cervical vertebra and the thoracic rib.
true
In a sternoclavicular sprain, the clavicle is generally displaced
upward and anteriorly
