Dorsal Root Ganglion (DRG) Therapy is THE most cutting-edge treatment for pain available in the United States. The Dorsal Root Ganglion lies at the posterior root of each spinal nerve. Pain signals travel from the lower limbs to the brain, passing through the dorsal root ganglion. DRG therapy targets the specific regions of the cord that are transmitting the pain and shuts down those painful signals directly by placing the leads directly over the DRG’s. This allows for greater and more targeted control of pain in the lower limbs.
