Which special test is used to indicate a rotator cuff tear?

The Drop Arm Test is a valuable clinical assessment used to indicate a rotator cuff tear, specifically involving the supraspinatus muscle. This test assesses the ability of the patient to smoothly lower an abducted arm. During the test, the arm is passively raised to shoulder height, and the patient is then asked to slowly lower it back to their side. If the individual is unable to lower the arm in a controlled manner or if they experience significant pain while doing so, this suggests that there is an issue with the rotator cuff, typically indicating a tear.

The underlying premise of the Drop Arm Test relies on the integrity of the rotator cuff in controlling shoulder movements. A rotator cuff tear impairs the muscle's ability to stabilize the shoulder and perform its function effectively, leading to weakness and often pain when attempting to lower the arm.

Other tests listed have different focuses. The Empty Can Test is also associated with the supraspinatus but emphasizes strength rather than control during motion. The Apprehension Test primarily assesses for shoulder instability, particularly in relation to dislocation. The Neer Test evaluates for subacromial impingement rather than addressing rotator cuff tears directly. Overall, the Drop Arm Test specifically targets the mechanics and function
