Brief Summary:
The objective of this study is to evaluate the efficacy of BurstDR dorsal column stimulation, compared with conventional medical management, in improving pain and back-related physical function in subjects suffering with chronic, refractory axial low back pain with a neuropathic component, who have not had lumbar spine surgery and for whom surgery is not an option.

Condition or disease Intervention/treatment Phase
Chronic Low-Back Pain Refractory Pain Neuropathic Pain Device: Spinal Cord Stimulation Other: Conventional Medical Management Not Applicable

Detailed Description:

A prospective, multi-center, randomized, controlled clinical study with an optional crossover component. The study is designed to evaluate the efficacy of BurstDR SCS in the treatment of chronic axial low back pain with a neuropathic component, compared to conventional medical management (CMM).

Subjects will be followed in-clinic at 1,3, 6, 9, 12, 18 and 24 months and via phone call or optional clinic visit at 15- and 21-months. The primary endpoint will be assessed at the 6-month follow-up visit. Upon completion of the 6-month follow-up visit, subjects who are dissatisfied with therapy and receiving inadequate improvement with their treatment assignment will be allowed to cross-over to the other treatment arm, if desired.

The study will enroll up to 270 patients at up to 30 sites. Subjects will be randomized in a 3:2 fashion to yield approximately 200 evaluable subjects for the primary endpoint analysis.
