Stimulation of the DRG has been done in Europe and Australia for about 5 years, and there are several good research studies showing profound levels of improvement for nerve injury syndromes (eg chronic nerve pain after hernia repair, hip or knee surgery), and especially in CRPS. In fact, DRG Stimulation is FDA-approved specifically for the treatment of CRPS, and in this patient population DRG stimulation has been shown to give superior levels of pain relief as compared to traditional spinal cord stimulation.

The process begins with an office evaluation and thorough history and physical. Part of the history is discussing what treatments you may have already tried. If you are found to be a good candidate, the next step is undergoing a 5-10 day trial. This is basically a temporary version placed through a spinal needle under light sedation, which you then get to go home with and try out for a week. After 5-10 days it’s removed in the office and if it didn’t work well for you for whatever reason, that’s that. It’s a low risk, minimally invasive chance to test it out and see if it works for you. If it does work well, however, it can then be implanted longer term.
