Ligament tear rehabilitation training methods mainly include muscle strength training, joint mobility training and sensory retraining. After a ligament tear, rest, braking and ice compresses should be applied immediately to reduce edema and bleeding, and then a brace or plaster should be worn to immobilize the ligament according to the situation, and rehabilitation training should be carried out after the pain symptoms are relieved. 1. Muscle strength training: the initial recovery period, patients should pay attention to the muscle strength training of the adjacent muscles of the torn part to prevent muscle atrophy, and so on ligament recovery to a certain extent, you can carry out the anti-gravity muscle training, with the increase of muscle strength can use dumbbells, elastic bands, etc. to carry out resistance training. 2. Mobility training: ligament tears are usually fixed internally and externally. After contact fixation, active or passive joint mobility training and manipulative treatments such as joint loosening should be carried out to prevent contracture of joint tissues. 3. Sensory training: Sensory training includes deep sensory and superficial sensory training, usually on the wound site for touch, pain, temperature, vibration, proprioceptive feedback and so on. It is recommended that the rehabilitation training of ligament tear patients should be carried out under the guidance of a rehabilitation physician, in a gradual manner, to prevent re-injury.
