sulcus sign
a test for ligamentous laxity of the glenohumeral joint performed by pulling the humerus inferiorly. A positive test is a resulting inferior subluxation dislocation and a visible / palpable sulcus.
Hawkin's sign
a test for acromioclavicular joint impingement and supraspinatus tendon tear/weakness. The test is performed by first having the patient flex their arm and elbow to about 90 degrees. Stabilize this position then proceed to internally rotate the shoulder
Jobe's test
the empty beer can test, a test for weakness / tear of the supraspinatus muscle. It is performed by having the patient internally rotate their arm to have the thumb pointing to the floor. The arm is then abducted to 90 degrees (some texts may say to also flex the arm to 30 degrees)
Speed's sign
a test for bicipital tendon stability in the bicipital groove. It is performed by first having the patient flex their arm to about 90 degrees with the elbow extended and forearm supination. Then apply a downward force as if to place the arm back into neutral position, but instruct the patient to keep the arm flexed. This engages the patient's arm flexors, including the biceps. A positive test is reproduced pain at the bicipital groove.
Yergason test
a test for stability/pathology of the bicipital tendon in the bicipital groove. It is performed by stabilizing the forearm, then flexing the elbow to 90 degrees with the humerus in neutral position then externally rotating the shoulder / supinating the forearm against resistance. The biceps is a muscle involved in supination and this action will mobilize the bicipital tendon. A positive test is pain or the bicipital tendon slipping out of the bicipital groove. Palpation of the bicipital groove during the test will help assess the tendon's stability in the groove.
