SM II_Shoulder Review

shoulder is forced into excessive abduction, external rotation, and extension. During palpation, you find the head of the humerus to be sitting anterior and inferior of the glenoid fossa

• glenohumeral dislocation

• glenohumeral subluxation

• scapular dyskinesis

• acromioclavicular joint sprain

pain over the acromioclavicular joint, overriding clavicle on the acromion of the affected shoulder; Palpation reveals a mobile clavicle as you press down on it, and it pops back up.

• sternoclavicular joint sprain

• glenohumeral joint sprain

• acromioclavicular joint sprain

• scapulothoracic joint sprain

During palpation, point tenderness is elicited over the head of the humerus. Weakness is shown when the empty can test is performed

• Glenohumeral dislocation

• Rotator cuff tear

• Biceps tendon rupture

• Clavicle fracture

Pain presented under the acromion process of the scapula. Pain also with overhead movement

• Scapular dyskinesis

• Impingement syndrome

• Rotator cuff strain

• Bicipital tendinitis

Pain presented within the bicipital groove. Pain with excessive overhead and internal rotation movements.

• Scapular dyskinesis

• Impingement syndrome

• Rotator cuff strain

• Bicipital tendinitis

pain is near the sternal end of the clavicle; pain with shrugging of the shoulders and reaching overhead

• Sternoclavicular joint sprain

• Acromioclavicular joint sprain

• Glenohumeral joint sprain

How would you describe, through observation, what scapular dyskinesis is?

• A condition where the scapula moves abnormally

• A condition where the scapula is perfectly aligned

• A condition where the scapula is immobile

• A condition where the scapula is missing

Injury to the long thoracic nerve and/or spinal accessory nerve can be a possible contributing factor for developing scapular dyskinesis because:

• they affect the stability and movement of the scapula.

• they increase the strength of the shoulder muscles.

• they enhance the flexibility of the shoulder joint.

• they improve the blood circulation to the scapular region.

Why do you think it’s important for this baseball player to strengthen their scapular stabilizing muscles?

• To improve throwing accuracy and prevent injuries

• To increase running speed

• To enhance batting power

• To improve team communication

This special test can be used to determine if there is rotator cuff tendinitis

• AC joint instability test

• Apprehension test

• Impingement test

• Empty can test
