Supraspinatus muscle injury occurs when the patient suffers from rupture of the muscle fibers of the supraspinatus muscle due to the external force, and there will be local bleeding and pain while affecting the movement of the shoulder joint. In the acute stage, no exercise is allowed, and shoulder braking should be given, while topical application of ointment for treatment of bruxism should be applied. Adjunctive treatment, such as physiotherapy, baking electricity or oral blood-activating drugs, should also be given. In the later stage, the muscle fibers have gradually healed after supraspinatus injury, but the patient’s shoulder joint activities appear to be limited, at this time, appropriate shoulder exercise can be carried out. When exercising, it is best to carry out proper shoulder rehabilitation training under the guidance of a rehabilitation doctor. The patient can perform pendulum movement or small arc circle movement of the shoulder to relieve local muscle adhesion and improve the range of motion of the shoulder joint.
