Central baroreflex failure in patients with spinal cord injury results in serious orthostatic hypotension. We examined if transcutaneous electrical stimulation regulates arterial pressure in those patients. We identified skin regions capable of increasing arterial pressure and determined respective transfer function. Using the transfer function, we designed the feedback regulator (i.e., bionic baroreflex system) to control arterial pressure. Orthostatic stress decreased arterial pressure profoundly. Activation of bionic regulator restored and maintained arterial pressure at pre-specified levels. We conclude that the transcutaneous bionic system is noninvasive and capable of stabilizing arterial pressure in patients with spinal cord injury.
