Recovery of paralysis after spinal cord injury is closely related to the location and severity of the injury. Generally, the higher the location of the injury, the more difficult it is to recover and the worse the prognosis. A cervical injury to the spinal cord may result in quadriplegia, while a thoracic paraplegia may only result in immobility of the lower extremities, and when comparing the two, it is definitely more difficult to recover from a cervical injury and the prognosis is worse. The more severe the injury, the worse the prognosis. According to current statistics, if the injury is incomplete, 50% of the patients can recover the muscle strength of the lower limbs to more than level 3, which means that they can basically complete their daily activities. For paraplegic patients with complete injury, the chance is less than 1%, so the recovery of paralysis in spinal cord injury patients is closely related to their condition. It should also be reminded that with the current medical conditions and medical technology, most patients with spinal cord injuries do not have complete recovery of their motor and sensory impairments. The goal of rehabilitation is that the patient can participate in family and social life despite the disability in physical function, and become a person with a disability but not an invalid, which is the so-called full rehabilitation.
