Scapular Retraction Test assesses RTC strength and labral symptoms.

• A. Biceps tendinopathy
• B. Subscapularis function
• C. RTC strength and labral symptoms
• D. AC joint pathology

Answer: (C)

The effect of scapular positioning on how the shoulder moves is the key idea here. When you retract the scapula, you change the way the glenohumeral joint sits, often increasing the subacromial space and putting the rotator cuff muscles in a clearer line of pull to center the humeral head in the socket. The scapular retraction test uses this change to reveal how well the rotator cuff can stabilize the shoulder and whether glenoid–labrum mechanics contribute to symptoms. If retracting the scapula improves strength or reduces pain during resisted movements, it points to the rotator cuff's role in the symptoms and suggests a labral component that is influenced by glenoid orientation. This makes the test most relevant to assessing rotator cuff strength and labral symptoms rather than other issues. Biceps tendon problems typically show tenderness at the bicipital groove and pain with elbow flexion or forearm supination, not a primary response to scapular position. Subscapularis function is usually evaluated with internal rotation–specific maneuvers, and AC joint problems present with symptoms localized to the joint itself, often with cross-body or horizontal adduction tests.
