Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease characterized by symmetrical and polyarthritis. With the development of the disease, the patient’s joints will be damaged or even deformed, swelling and pain when moving. So the joint is damaged, can the patient still exercise? In the acute stage of rheumatoid arthritis, the joint is obviously swollen and painful, accompanied by mild edema of surrounding tissues, local temperature increase and tenderness. At this time, the patient’s joint movement is limited or completely unable to move, and the morning stiffness time is about an hour. In the acute phase, patients should stay in bed, take medicine on time, limit swelling and painful joint activities, and avoid weight-bearing, excessive activity and cold stimulation. During rest, swelling and painful joint compression should be avoided, so as to avoid aggravating joint swelling and pain. < p > < p > when the symptoms are relieved and the acute phase is over, the patients should receive functional recovery training, mainly including joint and muscle training. Rheumatoid arthritis patients can carry out finger joint training, mainly including finger extension and flexion. During training, from distal to proximal, from distal interphalangeal joint to proximal interphalangeal joint, and then to metacarpophalangeal joint. Straightening and flexion should be done as fully as possible. It can be done with one finger or with multiple fingers. Patients can also do finger training, training should be from easy to difficult, gradually adhere to their own joint function training. Attention should not be paid to excessive activity and sudden force to prevent joint damage. In addition to joint training, patients can also do some aerobic exercise. Aerobic exercise can not only relax muscles, relieve spasm around joints, but also facilitate blood circulation and promote inflammation dissipation. < / P > < p > appropriate activities can greatly promote the functional recovery of patients with rheumatoid arthritis in remission stage, and can also improve the self-care ability of patients and help them establish confidence. Rehabilitation training needs long-term adherence, so it needs the cooperation and supervision of patients’ families. Only early adherence to functional exercise can reduce the degree of joint injury and improve the quality of life.
