Crank test for SLAP lesion

To perform the crank test, the patient abducts their arm 160 degrees while keeping the arm in the plane of the scapula. The elbow is flexed 90 degrees. The examiner then applies an axial load to the humerus with one hand while rotating the arm internally and externally with the other. Pain, a clicking sensation during the maneuver, or reproduction of symptoms similar to those experienced at work or sport indicates a positive test.
