Multicenter Study
DRG FOCUS: A Multicenter Study Evaluating Dorsal Root Ganglion Stimulation and Predictors for Trial Success.
Dorsal root ganglion stimulation (DRGS) is a powerful tool in the treatment of chronic, neuropathic pain. The premise of DRGS is similar to that of conventional spinal cord stimulation (cSCS), however, there is more variability in how it can be utilized. While it is this variability that likely gives it its versatility, DRGS is not as straightforward to implement as cSCS. The purpose of this study was to assess the efficacy of DRGS on a broad number of diagnoses, determine which dorsal root ganglia were associated with better outcomes for particular body parts/diagnoses, and evaluate what factors/parameters were associated with higher rates of trial success. ⋯ DRGS can be an effective treatment for a variety of neuropathic pain syndromes, in addition to CRPS. It is recommended that a minimum of 2 leads should be utilized per area being treated. In addition, this therapy was shown to be equally efficacious in any body part/region so long as the area being treated is focal and not widespread.

Case Reports Multicenter Study
Early US Experience With Stimulation of the Dorsal Root Ganglia for the Treatment of Peripheral Neuropathy in the Lower Extremities: A Multicenter Retrospective Case Series.
Peripheral neuropathy is a chronic pain disorder involving physical, chemical, or metabolic damage to peripheral nerves. Its pain can be intense and disabling. Dorsal root ganglion (DRG) stimulation is an effective treatment for neuropathic pain, including cases with the limited regional distributions that often characterize peripheral neuropathy. ⋯ This small multicenter retrospective case series provides preliminary evidence that the painful symptoms of general peripheral neuropathy in the lower extremities, as well as associated pain medication usage, can be effectively managed by DRG stimulation at the L4-S1 spinal level. Importantly, this treatment appears efficacious for peripheral neuropathy.
