Motor rehabilitation after spinal cord injury is one of the most important topics of concern for patients with spinal cord lesions, clinicians and rehabilitation physicians. In the past, the motor rehabilitation of spinal cord injury patients was mainly through muscle strength training, peripheral electrical stimulation, weight loss walking training, balance training and level walking training. The treatment of the injured nerve itself is very limited. DC electrical stimulation is a non-invasive neurointerventional treatment that can excite the motor cortex, alter cerebral neurotransmitter regulation and cerebral blood flow as well as produce neural network signal modulation by administering low DC stimulation (1-2 mA) transcranially or trans-spinally. Transcranial DC also has a distal effect, affecting the excitability of the spinal neural network, which in turn modulates spinal neural function. Combining transcranial or transspinal DC stimulation with rehabilitation therapy may improve the prognosis of spinal cord injury patients and enhance the effect of traditional rehabilitation therapy, making it a new method of motor rehabilitation therapy for spinal cord injury patients. At present, our department has already carried out transcranial and trans-spinal cord direct current stimulation treatment and achieved good clinical results.
