The rules of point selection are as follows: 1. Internal pain: the pain point is at the starting point of the subscapularis muscle (the inner end of the scapularis posterior receptacle), the stopping point of the trapezius muscle (the lower part of the scapularis posterior), and the starting point of the subscapularis muscle (the middle of the scapularis posterior). The pain can be relieved immediately by rubbing the corresponding symmetrical point on the healthy side. The functional activity will return to normal. 2, abduction pain: the pain point is at the stop of the supraspinatus muscle (equivalent to the front upper area of the attachment point of the greater tuberosity muscle of the humerus), the pain can be eliminated immediately by rubbing the symmetrical part of the healthy side, and the function can be restored. 3. Internal rotation pain: the pain point is under the ligament of the acromioclavicular joint and the outer 1/3 of the clavicle, and the attachment of the subclavian muscle. The pain in the symmetrical counterpart of the healthy side can be eliminated immediately. The function is restored. 4.External rotation pain: The pain point is at the starting point of the small round muscle (equivalent to the lower part of the external muscle attachment area under the back of the scapula). The pain in the symmetrical counterpart of the Jian side can disappear immediately and the function can be restored. 5.Back extension pain: the pain point is at the stop of the subscapularis muscle (equivalent to the humeral tuberosity near the joint capsule). The pain in the symmetrical part of the healthy side of the point can be eliminated immediately and the function can be restored. 6.Advance flexion pain: rare, the pain point is in the shoulder joint, the posterior part of the scapula, the start of the deltoid muscle on the healthy side, which is equivalent to the posterior part of the acromioclavicular joint, the stop of the supraspinatus muscle and the middle area of the start of the humerus muscle.
