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
