Video 3.4. Posterior Stress Test

The examiner demonstrates the appropriate technique for the posterior stress test with the patient lying supine on the examination table to stabilize the scapula. The patient’s shoulder is flexed to 90 degrees, adducted, and internally rotated with the patient’s elbow flexed to 90 degrees. The examiner then applies a posteriorly directed force to the humeral head. A test is considered positive if there is pain or a sense of instability with the maneuver.
