Early active or passive exercise and appropriate functional exercise, putting the joints and limbs in a certain position and changing the position in time; applying drugs, physiotherapy or joint functional traction and other measures to reduce the pain of the organism; these methods are important measures to stop the contracture of the forearm and hand muscle groups from occurring. Generally speaking, as long as the indications are properly mastered, early exercise therapy will have no effect on the original disease. The following are specific exercise therapies. 1.Empty hand retraction: hold the affected limb by hand for 30s to several minutes and then release it. 2, support weight retraction: help the patient to stand for about 20min and then lie down, mainly exercise the large and calf muscles. 3.Splint retraction: fix the affected limbs or joints with special splints for a few hours and then remove them. 4.Joint function traction: fix one end of the joint under appropriate posture, and pull the other end with appropriate weight intermittently. All of these treatments can achieve the therapeutic purpose by inhibiting muscle tension.
