A clinical test for assessing instability of a painful shoulder. The problem shoulder of a supine or sitting patient is passively abducted and rotated then fully stressed, while the examiner studies the patient's face for apprehension and examines the shoulder muscle for muscle spasm. The normal shoulder is manipulated in the same way and the two sides compared to detect loss of passive movement. The test needs to be performed carefully by an expert because of the danger of provoking an anterior dislocation in a very unstable shoulder.
