Spinal Cord Stimulation for Low Back Pain

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the acute and chronic effectiveness of the Advanced Bionics Precision(TM) Spinal Cord Stimulation System in subjects with failed back surgery syndrome and associated low back axial pain. Subjects will undergo a temporary or permanent trial to assess their candidacy for placement of an implantable pulse generator. Those who demonstrate a significant clinical reduction in pain will be enrolled in the chronic study. Subjects will be followed for 12 months post implantation to assess the long-term effectiveness of the therapy.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effectiveness of SCS Stimulation in Reducing Back Pain Associated With Failed Back Surgery Syndrome After 12 Months of Use. | Effectiveness of SCS stimulation in reducing back pain associated with Failed Back Surgery Syndrome after 12 months of use as measured by 0 - 10 numerical rating scale (Numerical Rating Scale, NRS), where 0 indicates no pain and 10 indicates pain as bad as you can imagine | 1 year | 
| Effectiveness of SCS Stimulation in Reducing Leg Pain Associated With Failed Back Surgery Syndrome After 12 Months of Use. | Effectiveness of SCS stimulation in reducing leg pain associated with Failed Back Surgery Syndrome after 12 months of use as measured by 0 - 10 numerical rating scale (Numerical Rating Scale, NRS), where 0 indicates no pain and 10 indicates pain as bad as you can imagine | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Patients Who Achieve a Significant Clinical Reduction in Back Pain Defined as >50% Reduction in VAS Score With Stimulation Compared With no Stimulation |  | 1 year |
