The lower limb is the most important part to support people to walk upright. It is precisely because of the powerful lower limb system that human beings can stand, walk and run for a long time. Most lower limb amputations are assisted by prostheses, crutches and wheelchairs.

Lower limb amputation also has the same postoperative complications as upper limb amputation. However, due to different amputation sites, there are different sports rehabilitation methods. ? For amputation below the ankle joint, patients generally do not use artificial limbs and wheelchairs, but are likely to use crutches to assist walking. Therefore, the sports rehabilitation of amputation below ankle joint includes the exercise of shoulder joint and arm strength. The exercises on the amputated side should include replacing the lower leg and thigh, hip joint and all joints above the joint. The main contents of the exercises are: stretching calf muscles and stretching soleus muscles. For amputation below the knee joint, patients are likely to use artificial limbs, so the coordination and adaptability between artificial limbs and their own organs are included in the practice. We should also pay attention to developing the ability of healthy limbs to compensate for the inconvenience caused by amputation. Knee amputation mainly includes: straight leg lifting, hip flexion, hip extension, knee extension on the healthy side and various muscle movements on the healthy side. ? During the amputation of the thigh root, patients usually use wheelchairs for daily activities. Just like using crutches, you need a series of exercises on your upper limbs and shoulders to support your ability to drive a wheelchair for a long time. People's hip bones have a good ability to support people to sit for a long time. However, patients with high amputation sit for much longer than ordinary people, so they need to do some abdominal exercises. The contents of the exercises mainly include: abdominal flexion exercises, sit-ups and hip lifting exercises, and various waist exercises.
