In clinical practice, if a patient has a supraspinatus injury, scientific and correct exercises can be performed, which can help the recovery of supraspinatus injury. The specific exercise method is to instruct the patient to take a standing position with both upper limbs hanging down naturally, then instruct the patient to hold a weight in the hand, and instruct the patient to flex the elbow joint while slowly moving the shoulder joint, which can make the muscles of the shoulder joint get contracted and stretched, which can strengthen the local muscle strength and increase the stability of the joint, which can help to recover the strength of the supraspinatus injury. In addition, the patient can be instructed to take a standing position, then both upper extremities hang down naturally, while flexing the elbow joint and making outward arcing movements with the shoulder joint as the axis. During the whole exercise process, the patient should be instructed to use slow force and not to use violence to avoid aggravating the injury of supraspinatus muscle.
