The ACCURATE study is a prospective, randomized, controlled, multicenter clinical trial designed to assess the safety and efficacy of the Spinal Modulation Axium Neurostimulator System as an aid in the management of chronic, intractable pain of the lower limbs, including unilateral or bilateral pain associated with one of the following conditions: Complex Regional Pain Syndrome (CRPS) or Peripheral Causalgia (also referred to as CRPS Type II).~Enrolled subjects were diagnoses with CRPS or peripheral causalgia; experienced pain for at least six months; and failed to achieve adequate pain relief from at least two prior pharmacologic treatments.~All subjects had a temporary trial neurostimulator (TNS). If the subject was a treatment success at the end of TNS they were scheduled for the fully implantable neurostimulator (INS) implant procedure. If not, subjects were exited from the study.
The purpose of this study is to evaluate the safety and effectiveness of the AXIUM Neurostimulator System for the treatment of chronic lower limb pain in persons diagnosed with Complex Regional Pain Syndrome (CRPS) or Peripheral Causalgia (PC).
