THE CHOICE FOR BETTER OUTCOMES*

With DRG stimulation you can achieve superior outcomes and deliver precise relief for patients suffering from focal chronic intractable pain.1


The Science Behind the DRG

The dorsal root ganglion (DRG) plays a critical role in the development and maintenance of chronic pain.2,3 It contains cell bodies of primary sensory neurons that undergo pathophysiologic changes underlying in chronic pain.4,5 The DRG’s unique pain processes and its anatomical considerations make it an ideal interventional target to treat various focal chronic intractable pain conditions.

The DRG has emerged as an exciting target for the management of focal intractable chronic pain.


Superior Pain Relief for Focal Chronic Intractable Pain

Conventional tonic SCS has been successfully used since 1967 to manage chronic, intractable pain in the trunk and/or limbs.5 But for pain locations outside of or more focal than the trunk and/or limbs—as seen in conditions such as CRPS, chronic intractable post-surgical knee pain and pain in the upper limbs—conventional tonic SCS has been less successful or has resulted in extraneous stimulation.1

Today there is a better solution: stimulating the dorsal root ganglion (DRG), which has been clinically proven to achieve pain relief in focal chronic intractable pain conditions.

Proof That DRG Therapy Works 

DRG stimulation’s effectiveness has been proven in many international studies along with the U.S. ACCURATE study, the largest randomized neurostimulation clinical trial that compares conventional tonic SCS with DRG stimulation, to treat complex regional pain syndrome (CRPS).

Results were sustained at 12 months, with DRG stimulation providing overall treatment success in 74.2% of patients, versus 53.0% in traditional SCS patients.1 This study data suggests that DRG stimulation may offer a meaningful treatment aid for patients suffering from chronic pain conditions who are currently underserved by traditional SCS.
