Brief Summary:
The primary objective of this study is to assess the effects of varying pulse width in suprathreshold dorsal column stimulation in patients with low back pain.

Condition or disease Intervention/treatment Phase
Pain Chronic Pain Back Pain Device: Precision Phase 4

Detailed Description:

This study will generate data which may allow Precision SCS devices to be used or programmed in such a way as to relieve pain while minimizing any uncomfortable sensations. This study will extend anecdotal reports into a prospective analysis of outcome data.

Patients invited to participate in this study will have recently been implanted with the Precision system, or will be eligible for SCS therapy and will have already selected therapy with the Advanced Bionics Precision system, independent of possible inclusion in this study.

Primary Outcome Measures :
  1. Pain Severity, as Measured on the 11-point (0-10) Numerical Rating Scale (NRS) [ Time Frame: Within 6 months post-implantation ]
    Pain severity as measured by NRS quantifies pain, where 0 is "no pain" and 10 is "worst pain imaginable"
