Shoulder subluxation is often mistaken for a bone or even joint problem that requires orthopedic repositioning or surgery, but it is not. Shoulder subluxation is usually referred to as glenohumeral subluxation, which occurs in the early stage of stroke, especially when the whole upper limb is in flaccid paralysis, when it starts to stand or sit, often due to the effect of gravity. The main symptom is the depression under the shoulder peak in sitting position, and the gap between the shoulder peak and the humeral head increases under X-ray. Once a subluxation of the shoulder joint occurs, the following methods should be taken to correct it: 1. The normal range of motion of the shoulder joint should be maintained. These activities include not only the passive movement of the scapula and upper extremity, but also bed movement, or transfer to a chair and posture placement in the prone and seated positions. 2. The activities and tension of the stabilizing muscles around the shoulder joint should be strengthened. The activities of the affected arm with weight can be used to reflexively stimulate the muscles through the squeezing of the joint. If the patient is in a sitting position, the elbow joint of the affected upper limb is straight, the wrist joint is dorsiflexed, the affected hand is placed slightly lateral to the hip level, and then the torso is allowed to tilt to the affected side, using the patient’s weight to make the joints of the affected limb compressed and weight-bearing. The rehabilitation therapist must use hand assistance to ensure proper scapular position during lengthening on the affected side. In addition, the movement of the relevant muscles can be induced more directly by careful graded stimulation. The rehabilitation therapist supports the affected arm with one hand by extending it forward while the other hand gently taps the humeral head upward. The pulling reflex of the elbow increases the tone and mobility of the deltoid and supraspinatus muscles. The affected arm is kept extended forward and the rehabilitation therapist does rapid, repeated squeezing through the palm of the affected hand in the direction of the shoulder to keep the patient’s hand extended forward and prevent shoulder retraction. The therapist uses the hand to make rapid rubs over the infraspinatus, deltoid and triceps muscles, from proximal to distal. Ice may be used for rapid rubbing, which may stimulate the activity of the relevant muscles. 3. Correcting the posture of the scapula The rehabilitation therapist may use those activities that exercise the proximal end of the trunk to release the spasticity of the distal end of the scapula. For example, the hemiplegic side is turned over, the upper limb of the affected side is weighted, the weight is shifted to both sides, and the scapula is moved. When moving the scapulae to full supination and forward extension, the therapist needs to move the patient’s shoulders forward at the same time, otherwise the healthy side shoulder is backward and the affected side shoulder forward extension is only an appearance. Good postural placement is important, both during the day and at night, and the patient should be encouraged to frequently use the healthy hand to help the affected upper extremity to do full supination. It is important to note that there should be no pain in the shoulder joint or its surrounding structures during the activity; if there is pain, it indicates that certain structures are involved and the treatment approach must be changed. It is well documented that shoulder slings do not reduce subluxation, but rather interfere with posture, braking the upper extremity, increasing flexor tone, and impeding normal gait, so they are generally not recommended. In stroke patients, early and correct management can prevent shoulder subluxation.
