Dorsal Root Ganglion Stimulation

Dorsal Root Ganglion Stimulation

Dorsal root ganglion stimulation (DRGS) has emerged as an important refinement and advancement in the application of neuromodulation therapy for pain management, demonstrating efficacy in several chronic pain conditions as well as a variety of anatomic locations. DRGS employs a smaller diameter electrode than conventional spinal cord stimulation (cSCS), positioned along the peripheral nerve root where the sensory fibers are discretely separated from the motor fibers. Consequently, DRGS improves upon certain shortcomings encountered with cSCS such as positional-related changes in stimulation efficacy and paresthesia, difficulty in coverage of certain body parts such as the foot and pelvic region, paresthesias in unwanted areas, and decreased pain relief over time.
