empty can test
An orthopedic test of the shoulder, used to determine the integrity of the supraspinatus muscle. With the patient sitting or standing, the shoulder is fully internally rotated, abducted to 90 degrees, and placed in 30 degrees of forward flexion, as if emptying a beverage can. The patient then attempts to maintain this position against resistance. Inability to hold this position, or pain while holding it, suggests pathology of the supraspinatus muscle.Synonym: Jobe test
