Shoulder stiffness should be divided into two aspects, as follows: 1, shoulder joint stiffness: not enough mobility, such as often seen in frozen shoulder, rotator cuff injury, and rotator cuff impingement syndrome, etc., are caused by adhesions of the joint capsule; 2, shoulder muscle stiffness: most of them are caused by muscle strain, such as now some people long-term ambulation or long-term head down to look at the phone, play computer, will cause shoulder muscle strain, after the strain In fact, there will be adhesions and stiffness of the muscles and ligaments. Whether it is shoulder stiffness or muscle stiffness, the principle of treatment is to release the adhesions, and you can go to the rehabilitation medicine department for physical therapy. In the case of shoulder stiffness, on top of the release of adhesions, active and passive exercises of the shoulder joint are required to increase joint mobility and reduce the degree of adhesions. In addition to the release of adhesions, patients with stiff shoulder muscles need more health education and lifestyle changes, such as long term ambulation and 5 minutes of activity every 30-40 minutes, which may alleviate the degree of muscle strain.
