[TESTS] Cross Chest Or Horizontal Adduction Test [STRUCTURES INVOLVED] Assesses acromioclavicular joint impingement. Passively move the humerus across the chest. As the humerus approaches full horizontal adduction, question the patient regarding pain in the acromioclavicular joint. Lightly place the fingers of your other hand over the acromioclavicular joint to palpate for crepitus and separation. This procedure compresses or impinges the acromioclavicular joint and is painful if internal derangement or instability exist. Perform this test on the uninvolved shoulder and compare bilaterally. [POSITION OF THE ARM] 
With the patient supine or standing, grasp the distal humerus with one hand and position it in 90 degrees of abduction
