Neer's test is used to diagnose which condition?

• A. Rotator cuff tear
• B. Adhesive capsulitis
• C. Possible subacromial bursitis
• D. Impingement of the supraspinatus tendon or bicep tendon

Answer: (D)

Neer's test targets shoulder impingement in the subacromial space. By passively flexing the arm with the scapula stabilized and the shoulder internally rotated, the space under the acromion narrows and the tendons crossing there—primarily the supraspinatus tendon, and often the long head of the biceps tendon—are pinched. Reproducing anterior shoulder pain with this maneuver indicates impingement syndrome, which is why the best answer points to impingement of the supraspinatus tendon or biceps tendon.

Adhesive capsulitis would mainly cause global restriction of motion rather than a focal impingement sign. Subacromial bursitis can cause similar pain but Neer's test is specifically about impingement mechanics. A rotator cuff tear can be related but Neer's test is used to identify impingement rather than to diagnose a tear per se.
