[TESTS] Supraspinatus Strength Test Or The Empty Can Test [STRUCTURES INVOLVED] Assesses the strength of the supraspinatus muscle. Ask the patient to maintain this position. Place your hands on the superior aspect of the elbow and press downward. Compare the patient's ability to resist your downward pressure with both the involved and uninvolved shoulders. Decreased ability of the involved shoulder to resist your downward pressure as compared to the uninvolved shoulder is indicative of supraspinatus weakness. This test may also elicit pain, indicating inflammation and muscle weakness. [POSITION OF THE ARM] 
The patient stands with both arms in 90 degrees of abduction, 30 degrees of horizontal adduction and full internal rotation.
