Empty beer can test: a positive test indicates rotator cuff tear, specifically, supraspinatus muscle tear; Drop arm test: a positive test indicates a supraspinatus tear; External Rotation test: a positive test indicates an infraspinatus or teres minor tear; Lift-off test: a positive test indicates subscapularis pathology
The Gerber Lift-off test is the established clinical test for examination of the subscapularis. [3] The bear hug test (internal rotation while palm is held on opposite shoulder and elbow is held in a position of maximal anterior translation) for subscapularis muscle tears has high sensitivity. Positive bear-hug and belly press tests indicate ...
In both tests, the patient is placed in a standing or sitting position, and the arms are raised parallel to the ground in the scapular plane. [2] The tests differ in the rotation of the arm; in the empty can test, the arm is rotated to full internal rotation (thumb down) and in the full can test, the arm is rotated to 45° external rotation, thumb up.

If pain disappears and shoulder function remains good, no further testing is pursued. The test helps to confirm that the pain arises primarily from the shoulder, rather than being referred from the neck, heart, or gut. If pain is relieved, the test is considered positive for rotator-cuff impingement, of which tendinitis and bursitis are major ...
Subscapularis, 13. Infraspinatus, 14. Teres minor), 15. Biceps muscle. The rotator cuff is a group of muscles and their tendons that act to stabilize the human shoulder and allow for its extensive range of motion. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are: supraspinatus muscle; infraspinatus muscle
The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, infraspinatus, teres minor and supraspinatus. [9] These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the glenohumeral joint, along with humeral abduction.
A doctor saw Prince twice in the weeks before he died and showed up at the musician's house to drop off test results just as he was pronounced dead.
Jobe's test is a physical exam test that is used to detect anterior shoulder instability. It is used to distinguish between anterior instability and primary shoulder impingement. This test should be performed after the Apprehension test. [3] This test was named for Christopher Jobe. [4]
