1. The main skill of rehabilitation therapy is to master the strength of the activity. Early passive activities require gentle and soothing, so as not to cause intolerable pain, to achieve the purpose of preventing tendon adhesions and joint stiffness. In the active rehabilitation exercise stage, patients are instructed to perform resistance training in a gradual manner to enhance muscle strength and endurance. Physical therapy is performed before exercise to promote blood circulation and increase the joint and muscle distraction effect. 2.From 10 days after reimplantation, the patient’s fingers are basically alive. Instruct the patient to do contraction training of forearm extensor and flexor muscles, the contraction of muscles can promote blood circulation to improve venous and lymphatic reflux, and the excitatory contraction of muscles can also prevent disuse muscle atrophy. The patient is instructed to move 30 to 50 times a day, and to increase the amplitude of the practice 3 weeks after the operation, and to cooperate with infrared, ultra-short wave, microwave, TDP and other physical therapy to facilitate the early recovery of the injured finger function. 3, 4-6 weeks after surgery, the replanted finger bone has healed, remove the internal fixation, increase the active and passive flexion and extension training amplitude of the injured finger, the application of manipulation or joint movers to practice, such as joint stiffness or rigidity, feasible manipulation traction and then bending activity training method, increase the joint activity angle of about 2 ° ~ 3 ° per day, the time increased from 10 minutes to 20 ~ 30 minutes. 4.The rehabilitation care training should start at 5 minutes each time, 1~2 times a day, and increase the time of each training with the extension of postoperative days, but should not exceed 30 minutes. Each training should be carried out under the guidance of nursing staff, and gradually teach the patient to master the magnitude and strength of the training, so as not to cause the fracture to be displaced or the tendon to be ruptured again due to the eagerness to cure and excessive force. 5. The recovery of sensation is an indispensable part of functional recovery. The application of sensory re-education methods, including sensory training, thermo-sensory training and comprehensive training, can make full use of the plasticity of the central nervous system, raise the recovery of sensory function to the brain hand center, and greatly improve the quality of recovery after sensory nerve repair.
