SPARC Bladder Mapping and Training Study

Spinal cord epidural stimulation will be administered through a multi-electrode array implanted in the epidural space over the dorsum of the spinal cord. An implanted package containing stimulating circuits, rechargeable battery, and wireless communication activates the electrodes (16 platinum electrodes arranged in three columns of \[5-6-5\]). The pattern of electrically active electrodes, as well as electrode voltage, stimulating frequency, and stimulating pulse width will be varied to facilitate effects toward bladder function.
