[TESTS] Anterior Instability Test [STRUCTURES INVOLVED] Detects glenohumeral joint anterior instability. Inferior Glenohumeral Ligament Grasp the distal humerus at the elbow and support the arm with the shoulder abducted 90 degrees and externally rotated 60 to 80 degrees. The elbow should be flexed 90 degrees. Place the thumb of your other hand in the axilla on the anterior inferior humeral head with your fingers on the posterior aspect of the humeral head. While maintaining elbow flexion and neutral shoulder rotation, apply a posterior force to the humerus as the fingers of your other hand push the humeral head anteriorly. Utilize your thumb to appreciate the amount of anterior translation. Repeat the test as you increase the amount of glenohumeral abduction. As the humerus is abducted, you may feel varying amounts of anterior translation and laxity. If the capsular structures are intact you should note a firm end point at the end of each anterior levering maneuver. Also, compare bilaterally. Lack of a firm end point, patient apprehension and pain, and excessive anterior levering may indicate capsular structure injury. [POSITION OF THE ARM] 
Position the patient supine with the glenohumeral joint slightly over the table edge.
