Advanced neuromodulation techniques: Dorsal root ganglion stimulation

Abstract

Objective: The dorsal root ganglion (DRG) houses the somata of primary sensory neurons and is located bilaterally along the posterior root at each spinal level. The DRG is involved in neuropathic pain and is therefore an attractive target for neuromodulation therapies. A specialized system now allows leads to be chronically implanted directly adjacent to DRGs. This report describes the procedures for implementing DRG stimulation. Practical problem-solving strategies from an experienced implanter are provided.
