Rehabilitation training after dislocation of the arm mainly includes two kinds of rehabilitation in the suspension period and later rehabilitation. 1. Suspension rehabilitation: after dislocation of the arm, first of all need to reset, fixation, so that the dislocated joints to restore the original anatomical position, the affected limb is often fixed by the plaster or support, suspension for 2 to 3 weeks. During the suspension period, the shoulder and wrist joints can be functionally exercised, such as daily fist training, divided into three groups, each group 100-120 times, etc., in order to avoid joint stiffness and atrophy. 2. Post-rehabilitation: After the suspension period, the patient can perform elbow flexion, extension and rotation exercise, 1 to 2 hours a day, step by step until it returns to normal mobility. After the joint is stabilized, we need to further strengthen the muscle strength and endurance training, such as weight-bearing training, etc. The purpose is to stabilize the joint and prevent secondary dislocation. The patient should choose the correct rehabilitation training after dislocation of the arm. If the dislocated joint fails to regain normal mobility for a long period of time, it is necessary to consult a doctor as soon as possible to clarify the cause, and if necessary, surgical release.
