Spinal cord injury cannot be completely recovered because the spinal cord belongs to the central nervous system, which is considered irreversible in principle after a central nervous system injury. Some patients will recover part of their function or most of their function after surgery or after treatment, but the golden period for rescue after spinal cord injury is within 6 hours, and no secondary injury to the spinal cord is caused during the process of transportation. There is a group of patients in the clinic, that is, the car accident caused lumbar spine injury, these patients can move their toes a little bit, after about six months of recovery, the patient can walk on their own. Therefore, if there is still residual sensation or movement, it is very helpful for recovery. The recovery of the central nerve is in 3-6 months, and if it does not recover, it will not recover within six months.
