Shoulder complications are the most common complications after stroke. The pain, stiffness and subluxation associated with soft tissue injury in the shoulder are usually caused by four mechanical factors: (1) compression of the soft tissues immediately adjacent to the shoulder crest (2) abrasion of the soft tissues near the bone (3) pulling of the soft tissues (4) contracture of the soft tissues (5) subluxation of the shoulder joint. The incidence of shoulder subluxation is 60 -80% and has a significant impact on the recovery of upper limb function. Etiology The muscles around the shoulder joint on the hemiplegic side are hypotonic and the muscles around the shoulder joint that maintain the normal anatomical position of the shoulder joint are relaxed, which reduces the strength of the stabilizing mechanism that holds the shoulder joint in place, causing the shoulder joint to fall out of its normal position in the joint socket. 1.Prevention of shoulder dislocation (1) Do a good job of protecting the shoulder joint in soft palsy to avoid excessive pulling on the paralyzed shoulder (2) Do not lie on the affected side for too long to avoid crushing the shoulder when it is unconscious (3) In hard palsy, when doing shoulder abduction and supination exercises, it is advisable to rotate the shoulder externally with the palm facing upward so that the greater tuberosity of the humerus avoids the extrusion of the scapula (4) At the same time, it is necessary to do passive activities of the scapula to increase the range of motion of the scapula. range of motion. (2) Correct the position of the scapula and resist scapular retraction (3) Move the scapular belt and move the scapula upward, outward and forward. (4) Stimulate the tension and activity of the muscles around the shoulder that play a stabilizing role (5) Keep the shoulder joint in a painless range of passive motion to maintain the normal range of motion of the shoulder joint
