Performing the dynamic labral shear test

A clinical maneuver developed by Dr. O'Driscoll, the dynamic labral shear test (DLST) is used to diagnose a SLAP lesion. It is performed with the patient supine with the affected arm off the side of the examining table. The shoulder is close to the edge of the bed so that the examining table mattress supports the scapula, but the humerus is free.
