These nerve bundles regulate the sensations that travel through nerve fibers along the spinal column to the brain. How Does Dorsal Root Ganglion Stimulation Work?ĭRG stimulation therapy works by stimulating dorsal root ganglia. It is particularly effective in relieving chronic lower limb pain associated with complex regional pain syndrome (CRPS) and peripheral causalgia (nerve damage). This kind of stimulation is better for smaller, more specific areas of pain because it can target a more specific location than traditional SCS. The procedure is similar to traditional spinal cord stimulation (SCS). Food and Drug Administration approved dorsal root ganglion stimulation for patients with Complex Regional Pain Syndrome (CRPS Type 1 and 2) in the lower extremities. Conditions Treated with Dorsal Root Ganglion Stimulation Patients have a small handheld controller that can change the stimulation settings. Although similar to spinal cord stimulation, DRG stimulation is more selective in targeting painful areas that can be difficult to reach with SCS.Ī small pulse generator is implanted in the upper buttock/low back or, with an extension, into the abdominal wall. The electrical leads have contacts that are placed over the DRG near the spinal cord. The pain management system consists of electrical leads and an implantable pulse generator. What Is Dorsal Root Ganglion Stimulation?ĭorsal root ganglia stimulation can be beneficial in the management of chronic pain. The DRG relays both pain and non-pain signals from the body to the central nervous system. These branches of nerves then spread throughout the body. The dorsal root ganglion (DRG) is a part of the spine where nerves branch off from the dorsal column (the back of the spinal cord). One of the types of ganglia present in the peripheral nervous system is a dorsal root ganglion. Who Can Benefit from Dorsal Root Ganglion?Ī ganglion is a part of the peripheral nervous system that connects the central nervous system to the organs, limbs, and skin.Conditions Treated with Dorsal Root Ganglion.What is Dorsal Root Ganglion Stimulation?. ![]() It is similar to spinal cord stimulation (SCS), which can block pain signals from a large area of the body however, DRG targets more specific areas of the body. Dorsal root ganglion (DRG) stimulation is a pain management option for people with difficult-to-treat chronic pain in specific areas of the lower body, such as the foot, knee, hip, or groin.
