A spinal cord injury (SCI) is damage anywhere along the spinal cord, usually from an accident or other trauma. Nearly half of people with SCI experience recurring nerve pain in areas below their injury. This pain may not go away, even with medications. Transcranial direct current stimulation (tDCS) is a procedure that may reduce nerve pain in people with SCI by “resetting” brain areas that react to pain. In tDCS, a weak electrical current is applied to the scalp using two electrodes on opposite sides of the head.
