ABSTRACT:
A stimulation system includes a stimulation source, an implantable stimulation lead, an implantable sensing device, and a controller. The stimulation source generates and transmits stimulation pulses to stimulation electrodes on the stimulation lead. The stimulation electrodes deliver the stimulation pulses to target nerve tissue in a nerve pathway to cause paresthesia in a portion of the person's body. Each stimulation pulse induces an action potential in a number of nerve fibers in the nerve pathway. The sensing device includes sensing electrodes positioned proximate the nerve pathway that detect compound action potentials of nerve fibers stimulated by the stimulation pulses. The controller modifies the stimulation pulses generated by the stimulation source and delivered to the target nerve tissue by the stimulation electrodes based on the detected compound action potentials to maintain a substantially constant level of paresthesia in the portion of the person's body.
