DRG Stimulation Dorsal Root Ganglion Neuromodulation for Treating Chronic Pain

Dr. Nandan Lad now offers a revolutionary new procedure that is set to change the whole way we approach treating CRPS. It’s called the DRG Stimulation, and it has already proven itself in clinical trials to offer superior pain relief over traditional SCS.

Devices to stimulate the dorsal root ganglion (DRG) became available in the mid-2010s for treating chronic pain, particularly in areas that were hard to treat with traditional spinal cord stimulation, such as the hand, chest, abdomen, foot, knee or groin.

The DRG is an easily accessible structure in the spine that plays a key role in the development and management of chronic neuropathic pain. It is a bundle of sensory nerve cell bodies within the epidural space. Each nerve root communicates to the dorsal root ganglion in a way that allows sensory messages from a defined area of the body. Therefore, applying stimulation to the DRG can permit focused therapy to a specific focal area.

How DRG Stimulation Does It Work?

DRG StimulationDRG Stimulation is a more advanced and refined version of traditional spinal cord stimulation. Instead of positioning the leads over the posterior aspect of the spinal cord, smaller and more precise leads are placed over the dorsal root ganglion itself. Specifically, the ganglia residing in the lumbar and sacral regions of the spine. This allows for greater and more targeted control of pain in the lower limbs.

In the industry’s largest study to date concerning lower limb pain associated with CRPS (ACCURATE Study), patients reported that the Axium DRG Stimulator gave them:

Significantly greater pain relief than SCS

No changes in paresthesia intensity (pins and needles sensation) when changing body position as compared to SCS.

A more precise and targeted area of administration i.e. no feeling of electrical stimulation outside their area of pain.

With DRG stimulation, Andrew Diaz is on the path out of ‘mind-boggling’ pain.

On his worst days, Andrew Diaz, 38, couldn’t leave his bed. “The pain was all-encompassing. I couldn’t think, I couldn’t see properly. It was debilitating,” he recalls.

On a scale from 1 to 10, the pain on those days rated as a solid 10. Most days, he hovered around an 8, which meant he could move around enough to meet his most basic needs, but normal daily activities were still out of the question. “There was no going to the mall or the store with my wife or kids or anything like that,” he says.
