Rehabilitation training after the swelling goes down includes local muscle contraction exercise, joint function exercise, resistance training and daily exercise. 1. Early stage of rehabilitation: local cold compresses can be applied continuously within 72 hours after the swelling of the leg to promote the swelling to subside. Patients can perform daily leg contraction exercises and move the toes and ankle joints to accelerate blood circulation and relieve pain. 2. Mid-rehabilitation: After the swelling subsides, patients can perform active joint activities, such as flexion, rotation, extension and straight leg raising exercises. In order to prevent stiffness and adhesion of the joints, exercise the leg muscles to prevent their atrophy. Rubber bands can be used to increase resistance during exercise to further improve joint mobility and increase muscle strength. 3. Late stage of rehabilitation: get out of bed, walk, squat, lift the leg, lunge and press the leg in a gradual manner to further move the joints and exercise the leg muscles. Until you can walk normally, you can carry out jogging, brisk walking and other daily exercise for the lower limbs, continue to exercise the leg joints and muscles, until complete recovery. After the leg is swollen, it is necessary to consult a doctor in time and carry out treatment and rehabilitation training under the guidance of a professional doctor, so as not to bring damage to the organism due to the improper way of exercise.
