Patients with frozen shoulder should pay attention to the following aspects when doing exercise therapy: 1. Prepare well before exercise The cause of frozen shoulder stems from poor blood circulation in the shoulder, degeneration of the soft tissues around the shoulder joint, injury and adhesions, which manifest as movement disorders and pain. Therefore, before carrying out exercise therapy, make sure that the affected shoulder is in a relaxed state. You can promote the blood circulation of the affected shoulder joint by shoulder massage or rubbing the shoulder with your hands to improve the blood supply state and relieve muscle spasm and tissue state. Local blood circulation can also be promoted through physical therapy such as local heat application. If the preparation before exercise is not sufficient, there is a risk of shoulder muscle injury, which will instead aggravate the pain and adhesions in the frozen shoulder. 2. Treatment should be individualized Everyone’s physique is different, so the course, condition and prognosis of frozen shoulder vary, so the treatment method is also different. Patients or therapists should choose the right exercise prescription for themselves according to the patient’s physical condition. You may want to try several treatment methods in the treatment to figure out the exercise method that suits you. 3.The treatment process should be gradual. Because of shoulder joint adhesions, pain in the affected shoulder joint will occur during treatment. If the patient does not experience pain during the exercise therapy, the intensity of the treatment is not enough and should be increased. The intensity of treatment should be increased until the pain is felt in the affected shoulder joint. It should be noted that the intensity of treatment should not be increased blindly. Patients can set a standard for the intensity of treatment and strive for a certain progress in daily treatment, gradually increasing the intensity of the exercise, but do not exercise roughly, and do not force the shoulder joint to move passively, in order to avoid tissue tears, bleeding and other injuries, thus aggravating the adhesions. In other words, exercise therapy should be done in “minor pain”, not in “severe pain”. 4. Keeping warm after exercise Exercise therapy enhances the blood supply to the shoulder joint. If stimulated by external cold factors, it may cause vasoconstriction, reduce blood supply and slow down the metabolism of soft tissues, thus affecting the therapeutic effect. Therefore, patients can continue to apply hot compresses for 10-20 minutes after treatment, while paying attention to wearing good clothes and keeping the room temperature. 5.Other During the treatment process, the muscles of the affected upper limb should always be kept relaxed, pay attention to adjusting the treatment technique, pay attention to the intensity, amplitude, frequency and time of the exercise method. For the elderly and frail, patients with severe osteoporosis, patients with history of upper limb fracture (or recent history of trauma) and patients with shoulder and elbow dislocation, exercise methods should be chosen carefully to prevent serious adverse reactions or complications.
