Dorsal Root Ganglion (DRG) Therapy

The DRG in DRG Stimulation refers to the Dorsal Root Ganglion, also sometimes known as the posterior root ganglion. The Dorsal Root Ganglion lies at the posterior root of each spinal nerve. Pain signals travel from the lower limbs to the brain, on the way they must pass through the dorsal root ganglion. If you suffer from neuropathic chronic pain, a new type of therapy called dorsal root ganglion stimulation, or DRG stimulation, could help you find minimally-invasive and highly-effective pain relief. It is most effective for patients with complex regional pain syndrome (CRPS).

Abbott’s dorsal root ganglion stimulation (DRG therapy) is designed to manage chronic pain in specific areas of the lower body (e.g. foot, knee, hip, groin) that don’t respond well to traditional SCS. It has been shown to deliver statistically significant pain relief over traditional SCS for patients with complex regional pain syndrome (CRPS) and causalgia.

  • Abbott’s Proclaim™ DRG neurostimulation system is the only FDA approved DRG technology for CRPS and causalgia.
  • The system uses a proprietary delivery mechanism designed to navigate a lead toward the correct anatomical target.
  • This provides targeted relief at the source with consistent, safe and superior outcomes in patients with CRPS or causalgia – enabling the treatment of more patients with better results

The Proclaim DRG neurostimulation system reduced pain an average of 81% when measured at 12 months. The system provides persistent pain relief to 86% of patients when measured at 12 months. Proclaim DRG also provides statistically greater improvements in overall change in physical function, general health, and social function at 12 months.

If you’re suffering from nerve damage pain, complex regional pain syndrome, other forms of painful nerve disorders, then DRG may be very helpful at reducing your pain.

Our staff at Columbia Pain Management looks forward to hearing from you and discussing how neuromodulation may help you.
