Description of intervention(s) / exposure
Observational study on the effectiveness of DRG Stimulation. DRG stimulation is a type of Spinal Cord Stimulation (SCS) which targets specific neural structures with electrical therapy by implanting a stimulating electrode in the epidural space. Suitable subjects will first have a trial of the therapy to determine effect and if successful will have the full system implanted. Implanted subjects will be followed prospectively for 1 year with follow up observations at 1 week, 1 month, 3 month, 6 month and 12 months post implant.
