Dorsal Root Ganglion Stimulation

Interrupting pain signals sent to the spinal cord reduces pain and offers an effective option in pain management. Like spinal cord stimulation, dorsal root ganglion stimulation, or DRG stimulation, is used to block pain signals from the lower half of the body at the spinal cord. If you suffer from lower body pain, Ospina Medical offers dorsal root ganglion stimulation for pain management at our clinic in New York City.

Dorsal root ganglion stimulation is a form of neuromodulation therapy that uses electrical pulses to interrupt pain signals sent along the nerves to the spinal cord. It is like spinal cord stimulation, requiring a device to be implanted under the skin to place probes near the dorsal root ganglion to deliver electrical current. The difference between DRG and SCS stimulation is the exact placement and nerves affected. SCS is placed on the posterior portion of the spinal cord, while DRG stimulators are placed on the dorsal root ganglion. This group of spinal nerves is the pathway from the lower extremities for all sensory perception.

Effective Pain Management for CRPS

Dorsal root ganglion stimulation can offer the precision that is needed for controlling pain for nerve disorders like complex regional pain syndrome (CRPS). Patients first use DRG stimulation for a week trial to determine if it is effective for their chronic pain. If it is successful, the DRG stimulation device is implanted with up to four probes that affect the dorsal root ganglion. With a remote, patients can emit electrical signals that interrupt pain signals from lower extremity pain. DRG stimulation requires less electricity for effectiveness, which can mean longer battery life. It is also more targeted than SCS for specific pain control.

If you suffer from CRPS or other types of lower extremity pain, dorsal root ganglion stimulation may be an option for pain management. Contact our team at Ospina Medical to learn more about neuromodulation options for opioid-free pain management options like DRG stimulation and SCS, available at our clinic in Midtown Manhattan.
