Abstract
A system and method are provided to mitigate excitation of non-target regions of nerve fibers during spinal cord stimulation (SCS) of nervous tissue of a patient. The method and system deliver an SCS excitation waveform to an excitation electrode located proximate to a dorsal column (DC), the SCS excitation waveform shaped to excite a nerve fiber target region (TR) within the DC. The method and system also deliver a blocking waveform to a blocking electrode located proximate to the DR, the excitation waveform shaped to at least partially induce hyperpolarization into a nerve fiber non-target region (NTR) within the DR.
