Spinal cord injury is a serious and disabling injury, with 20-30 new spinal cord injuries per million people each year. With the advancement of modern medicine, more people with spinal cord injuries are surviving and receiving rehabilitation treatment. Therefore, the extent of potential functional recovery after spinal cord injury is a common concern for patients and their families as well as rehabilitation workers. Of course, the rehabilitation effect of spinal cord injury is closely related to the degree and level of injury, but the early intervention of rehabilitation is very important for the functional recovery of patients. Early rehabilitation intervention is essential to improve the patient’s ability to perform activities of daily living, which is the most basic activity that people must perform every day in order to live independently, and is not only important for everyone, but also closely related to the patient’s quality of life. It is a common concern of patients, their families and rehabilitation workers. A large number of clinical studies and experiments have shown that early rehabilitation interventions can not only effectively prevent various complications, but also have an important significance for the functional recovery of patients with spinal cord injury, among which the improvement of daily living ability has an extremely important role, which is a role that cannot be ignored by patients, families and society. Among the various activities of daily living, the restoration of walking ability is an issue of great concern to patients and their families. The following is an overview of the rehabilitation of walking ability after spinal cord injury. Rehabilitation of walking ability: In the past, most of the complete paraplegics in the thoracic segment and above relied on wheelchairs throughout their lives, and only complete paraplegics below the L1 level had the possibility of standing and practical walking after training. In recent years, due to the development and progress of rehabilitation engineering, rehabilitation biomechanics, rehabilitation training, rehabilitation devices, especially walking devices, paraplegics below T4 can stand up and have practical walking ability, so that it is possible for patients to return to society and participate in social activities. The rehabilitation method is as follows: firstly, the spinal stability is reconstructed through surgery, then the walking device (consisting of knee-ankle-foot orthosis and interactive hinge device) is used to achieve standing and walking, reducing the occurrence of complications. The ARGO is a functional walking aid that has achieved good clinical results. This walking device is based on the metal half-ring of the hip and sacrum as the lever fulcrum and the thoracic back strap as the force point. When the patient’s body weight is placed on one lower limb, the contralateral upper limb down support, so that the contralateral lower limb leaves the ground, the patient stretches his chest and crotch, apply force to the back straps, the contralateral lower limb step forward; step forward force through the steel cable to the contralateral lower limb, then move the crutch, so that the body weight forward, and turn to the contralateral lower limb, repeat the above action and take another step. In this way, the patient’s body is guided forward by the reciprocal movement of the patient’s body weight to both sides, thus enabling the patient to actually stand and walk with his or her own lower limbs. Thus, ARGO has made it possible for most paraplegics below the T4 level to escape from wheelchair dependence.
