Biceps Stretch Test indicates Biceps Tendonitis or Synovitis.

• A. Biceps Tendonitis or Synovitis
• B. SLAP lesion
• C. Impingement
• D. Rotator Cuff tear

Answer: (A)

The test is meant to stress the long head of the biceps tendon as it courses through the shoulder joint and into the bicipital groove. If the tendon or its synovial sheath is irritated, passively stretching the biceps reproduces pain in the anterior shoulder and often tenderness along the groove. This makes biceps tendonitis or synovitis the most likely diagnosis when this provocative stretch elicits tenderness or pain.

A SLAP lesion involves the labrum, and while biceps pathology can accompany labral tears, this stretch test targets tendon irritation more directly and isn’t as specific for labral pathology. Impingement and rotator cuff tear affect other structures and typically present with pain patterns or weakness during overhead movements and cuff-specific maneuvers, not the localized biceps tendon stretch.
