Kenneth B. Chapman, MD – Director, Pain Medicine

Dr. Kenneth Chapman presents an overview of current dorsal root ganglion stimulation (DRG-S) applications, outcomes, and future directions. Dr. Chapman explains the main differences between DRG-S and spinal cord stimulation (SCS). He mentions that among several distinctions, DRG-S is applied at subthreshold amplitudes that are imperceptible, while SCS is paresthesia-dependent. Dr. Chapman also mentions that DRG-S can facilitate pain neuromodulation by influencing the endogenous opioid system. He emphasizes additional benefits of DRG-S, including the management of joint nociceptive pain as demonstrated by a heightened quality of life, physical function, and mental health. Additionally, Dr. Chapman describes prospective DRG-S studies for low back pain.
