Which rotator cuff special test is also known as Jobe's test?

• A. Empty can test
• B. Full can test
• C. Dropping sign
• D. Patte's test

Answer: (A)

Focusing on the supraspinatus function, this test places the shoulder in a position that makes the supraspinatus work hardest and then resists that effort to provoke any pathology. The arm is raised to about 90 degrees in the scapular plane with the forearm internally rotated so the thumb points downward—like you’re emptying a can. The examiner then provides downward resistance as the patient attempts to lift. If there’s weakness or pain, it points to supraspinatus tendon issues such as tear or tendinopathy, or subacromial impingement under the acromion. The name comes from the “empty can” position of the arm. A variation called the full can test uses a thumb-up position to reduce some impingement, but the classic Jobe’s test is the empty can maneuver.
