Spinal zaps may steady blood pressure in spinal cord injury

This study tests whether transcutaneous spinal cord stimulation (TSCS) — a gentle electrical current applied through the skin — can help veterans with chronic spinal cord injury (SCI) better regulate blood pressure during exercise and cold exposure. Participants will receive both active and sham stimulation while using an arm bike or sitting in a cool room, and researchers will measure exercise endurance, heart rate recovery, core temperature, and thermal comfort. The goal is to see if TSCS can improve autonomic function, which often becomes impaired after SCI, leading to issues like orthostatic hypotension.
