Abstract: The residual neurological dysfunction after traumatic spinal cord injury seriously affects the life status and quality of life of patients. With the rapid development of biomedical technology at home and abroad, there have been a variety of neuroregulatory techniques, including electrical stimulation, magnetic stimulation, ultrasonic stimulation and near-infrared laser stimulation, but the effect is different. This paper reviews the application and mechanism of various neuroregulatory techniques in the field of traumatic spinal cord injury,to provide guidance basis for future basic research and clinical application.
