Cross Body Adduction Test | AC Joint Pathology

The Cross Body Adduction Test is an orthopedic test to assess for a sensitized Acromioclavicular Joint such as in osteoarthritis.

According to a study done by Chronopoulos et al. (2004) the cross-body adduction test has a sensitivity of 77% and a specificity of 79%. The authors do not recommend using this test as a standalone diagnostic tool.

To conduct the test elevate the arm to 90° of flexion and then add maximum horizontal adduction.A positive test will produce pain on top of the shoulder near the AC  joint.
