What does a positive result in the Empty Can Test indicate?

A positive result in the Empty Can Test indicates supraspinatus pathology. This test assesses the integrity and strength of the supraspinatus muscle, which is a critical part of the rotator cuff. In this test, the arm is positioned in a way that the supraspinatus is isolated and emphasized during the movement. If the patient experiences pain or weakness while performing the test, it suggests that there may be an issue with the supraspinatus, such as tendinopathy or a tear.

This understanding is crucial in the context of diagnosing shoulder issues, as supraspinatus pathology is a common injury among athletes and can significantly affect shoulder function. A definitive diagnosis often necessitates further imaging or clinical evaluation, but the Empty Can Test serves as an essential tool in identifying potential supraspinatus-related conditions.
