The rehabilitation of frozen shoulder includes oral medication, functional exercises, physiotherapy and surgery. For the initial stage of frozen shoulder, the clinical symptoms can be relieved by medication, which usually includes non-steroidal anti-inflammatory drugs, such as fotarine tablets, fotarine ointment, indomethacin, loxoprofen sodium tablets, celecoxib, etc. These drugs can relieve the local soreness and pain caused by frozen shoulder, promote the local aseptic inflammation to subside, eliminate local tissue edema, and increase the mobility of the shoulder joint. If the patient’s frozen shoulder develops to the stiffness stage, functional exercise is very important for recovery. During this stage, the shoulder pain symptoms gradually disappear, the stiffness of the shoulder joint and the limitation of movement are more obvious, and the range of motion is significantly reduced. The following are some of the more common functional exercise methods that can be used to promote the recovery of the shoulder joint: 1. Shoulder joint rotational exercise training: Take a sitting position, hold the stick flat with both hands, press the elbow joints against both sides of the body, push and pull the stick with force from the healthy hand to both sides, and make the shoulder joint on the affected side move, the movement must exceed the midline of the body, a group of 5-10 times. 2. Upper limb pendulum exercise: lean forward, put the healthy side hand on the table or chair, the affected side hand holds the object (2.5 kg), then carry out front and back, left and right, circular swing training, repeat each action 5-10 times. 3. One-handed wall climbing exercise: the patient stands sideways near the wall, crawl on the wall with fingers from the bottom up, crawl to the maximum angle of the shoulder joint, a group of 5-10, exercise 2-3 times a day. The patient should crawl up the wall with his fingers to the maximum angle of the shoulder joint. Functional exercises together with medication can lead to faster recovery of frozen shoulder. Physical therapy can also achieve good results, such as medical ozone therapy, silver needle therapy, etc. When these treatments fail to achieve more satisfactory results, minimally invasive treatment needs to be considered. The more commonly used clinical treatment is shoulder arthroscopy, which is less invasive, less bleeding and faster recovery. Through arthroscopic treatment, local adhesions and scar tissue can be loosened, and functional exercises of the shoulder joint should be strengthened in order to cure the disease faster. The most fundamental treatment for the recovery of frozen shoulder is the functional exercise of the shoulder joint. Patients need to take the initiative to perform shoulder flexion and extension, rotation exercise, and gradually under the guidance of a professional doctor, and with other treatment methods, the disease can be cured faster.
