Tennis elbow is a painful inflammation of the tendon at the beginning of the forearm extensor muscle on the outside of the elbow joint. The pain is caused by a chronic tearing injury caused by repetitive force on the forearm extensor muscle. Patients may experience pain when gripping or lifting objects with force. Tennis elbow is a common disease, not only in tennis and badminton players, but also in manual workers and housewives who repeatedly exert themselves in elbow activities. The pain often causes inconvenience in daily life and greatly affects the quality of life. Rehabilitation treatment: (1) Rest: Avoid activities that cause pain and do not exercise until the pain disappears. (2) Ointment: tricolor dressing, pain patch, acupuncture point dressing, etc. (3) Braces: Use a compression and resistance brace on the forearm, which can limit the force generated by the forearm muscles. (4) Acupuncture: move Qi and blood, stop pain and reduce swelling. (5) Physiotherapy: microwave therapy to accelerate the elimination of local inflammation. (6) Exercise therapy: perform training to strengthen the wrist extension muscles. (7) Gradual return to exercise: start exercise programs and arm movements needed for work activities. Reasonable treatment methods can accelerate the relief of tennis elbow pain, and active treatment can avoid the re-occurrence of the disease. We hope that all patients can get rid of the disease and resume daily life, work and sports to improve the quality of life.
