Effect of Pulse Width With Spinal Cord Stimulation
Effect of Pulse Width With Spinal Cord Stimulation
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.
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.
Inclusion Criteria:

 -  Have chronic low back pain following spine surgery (Failed Back Surgery Syndrome),
 which is primarily located in the low back, with minimal lower extremity pain.

 -  Have been permanently implanted with a Precision spinal cord stimulation (SCS) system
 within 6 months, or be an appropriate candidate for SCS and for the surgical
 procedures required for SCS as determined by the physician and have independently
 selected SCS with Precision for treatment.

 -  Be 18 years of age or older.

 -  Be willing and able to comply with all study related procedures and visits.

 -  Be capable of reading and understanding patient information materials and giving
 written informed consent.

 Exclusion Criteria:

 -  Have any significant medical condition that is likely to interfere with study
 procedures or likely to confound evaluation of study endpoints.

 -  Have any other chronic pain condition likely to confound evaluation of study
 endpoints.
