[TESTS] Apprehension Test [STRUCTURES INVOLVED] Detects anterior shoulder subluxation or dislocation. Inferior Glenohumeral Ligament While supporting the humerus at the elbow with one hand, grasp the patient's forearm with your other hand. Gently and gradually externally rotate the shoulder. If the patient has had a recent anterior dislocation or subluxation of the glenohumeral joint, apprehension or discomfort will occur as the shoulder approaches 90 degrees of external rotation. Be careful not to cause an actual anterior dislocation when externally rotating the arm. You may modify this test to detect more subtle cases of anterior instability by placing the patient prone on the examination table. Place one hand on the forearm and the palm of your other hand on the posterior aspect of the proximal humerus. Abduct and externally rotate the shoulder 90 degrees as you push the humeral head anteriorly. When anterior instability is present, this position accentuates the anterior subluxation and elicits further apprehension and patient discomfort. [POSITION OF THE ARM] 
Position the patient supine in a relaxed position on the examination table. Support the patient's arm with the shoulder abducted 90 degrees and the elbow flexed 90 degrees.
