The patient is supine with the examiner supporting the head so that the neck is in contralateral sidebending and ipsilateral rotation and flexion. The whole cervical spine and occiput is fixed and held in long-axis traction. With the other hand, the examiner contacts the shoulder with the forearm parallel to the table and pushes inferiorly to determine end feel. While maintaining the above position, the examiner asks the patient to resist by pushing the shoulder superiorly against the examiner's resistance for 7 seconds. The examiner then asks the patient to let go and, while stabilizing the head and neck, depresses the shoulder as far as possible for 12 seconds.
