Video 9.3. Cross-body Adduction Test

The examiner palpates the affected shoulder with her left hand overlying the patient’s acromioclavicular joint and the other hand supporting the patient’s wrist. Then, the examiner horizontally adducts the affected arm across the body, with the shoulder passively held in 90 degrees of forward flexion. Here, the patient notes that this horizontal adduction elicits pain in the area overlying the acromioclavicular joint, indicating a positive cross-body adduction test result, and associated acromioclavicular joint pathology.
