The rehabilitation training after leg fracture mainly includes the following aspects. Static contraction training, in the early stage of leg fracture fixation, should be mainly static contraction diastole, so that the quadriceps, triceps and biceps femoris muscles, etc., strength gradually increased, to prevent muscle atrophy, while speeding up the swelling to quickly subside, which is extremely beneficial for early recovery. After six weeks, the fracture end is relatively stable, and appropriate resistance joint flexion and extension activities can be performed, which can enhance the strength and power of the leg muscles, as well as prevent joint stiffness and restore the range of motion of the joint. Therefore, after the fracture of the leg, the rehabilitation training should be carried out according to different stages, using the corresponding methods to make the fracture recover to the fastest degree, and at the same time, the nutrition absorption should be strengthened to make the rehabilitation training achieve better results.
