The Paxinos test (cross-body adduction) is used to assess pathology of which joint?

Explanation:
Cross-body adduction loads the acromioclavicular joint by bringing the arm across the chest and compressing the AC joint where the clavicle meets the acromion. If this maneuver reproduces pain at the top of the shoulder or directly at the AC joint, it points to AC joint pathology such as arthritis or a sprain/separation. The test specifically stresses the AC joint rather than the glenohumeral joint, elbow, or scapulothoracic interface, so it best identifies AC joint problems.
