After the treatment of shoulder impingement, rehabilitation training must be carried out, and the following measures can be taken for recovery: 1. At the early stage of rehabilitation, passive exercises around the shoulder joint are required, that is, the patient does not exert any force during the exercise, but moves the shoulder joint with the help of the doctor or family members, and gradually increases the mobility of the shoulder joint. 2. For example, the patient can hold the shoulder flat for about 20 seconds and then slowly put it down. 3. In the later stage of rehabilitation, the patient can stop the passive exercises and do the rehabilitation training completely by himself, either by extending the time of the shoulder flat or by adding weight to the hand, such as holding a certain weight of dumbbell for rehabilitation training.
