The purpose of general rehabilitation and exercise therapy is to strengthen the muscles around the painful joints and to reinforce the damaged or weakened joint function. Although the muscles around the joint are strengthened, the joint itself is not cured and the pain continues to exist. McKenzie therapy is characterized by applying a force directly to the painful joint area to restore the damaged or weakened joint function. For example, it corrects the subtle bending of the joint and restores the lost motion area of the joint, thus eliminating the pain. Zhang Tingfeng, Rehabilitation Center, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine When you go to the hospital with joint pain, your doctor will often say to move your joints less, walk less, and go up and down stairs less. People with back pain should not do reverse stretching, etc., which means to move the painful parts as little as possible. In the acute stage, it is necessary to keep quiet when the pain is severe. However, when the pain and swelling disappear, you should actively move your joints as much as possible. If you do not move your joints, you will lose the movable area of the joints, and the function of the joints will be significantly reduced, and the pain will worsen.
