81-year-old elderly right wrist fracture exercise early to muscle isometric contraction, the middle can move the joint, late can increase active activities and weight-bearing exercises. 1. Early rehabilitation training: isometric contraction of the injured limb muscles can be carried out. The isometric contraction of muscles can promote the blood circulation of the affected limb to reduce swelling and stabilize the fracture, and prevent muscle atrophy or adhesion. 2. Middle stage of rehabilitation training: the muscle contraction training of the injured limb can be continued to gradually restore the movement of the fracture end, remote unfixed joints and the upper and lower joints at the fracture site, in order to increase the mobility of the joints and prevent muscle atrophy and stiffness of the joints. 3. Late stage of rehabilitation training: Rehabilitation training mainly involves active activities and weight-bearing exercises for the joints of the injured limb, so that the joints can be rapidly restored to the normal range of activities and normal strength of the limb. In order to restore the joint mobility of the affected joints, enhance muscle strength and restore the function of the limbs. Since the elderly are prone to osteoporosis, the recovery period may be relatively long, and care should be taken when performing exercises to avoid secondary injuries caused by excessive force or improper posture. It is recommended to consult a doctor in time and carry out rehabilitation exercises under the doctor’s guidance.
