简要总结
To determine the effects of varying spinal cord stimulation programming parameters, including stimulation rate, on pain intensity.
详细描述
This study compared the effects of high-rate subperception stimulation with the effects of low-rate subperception stimulation on pain intensity.

- •Pass study site's routine psychological/psychiatric evaluation within 180 days of the Trial Lead Insertion Visit
- •If taking any medications for chronic pain, must be on a stable prescription during the 14-day period prior to the Trial Lead Insertion Visit and agree to continue on the same prescription throughout study participation
- •Subject is willing and able to comply with all protocol-required procedures and assessments/evaluations
- •Subject is able to independently read and complete all questionnaires and/or assessments provided in English

结局指标
主要结局
Change in Back Pain Intensity
时间窗: For this measure, outcome was assessed at baseline, the end of the first intervention (3 or 4 days post-implantation, depending on the subject), and the end of the second intervention (6 or 8 days post-implantation, depending on the subject).
Back pain intensity was measured on a 0-10 numerical rating scale (0="no pain", 10="worst pain imaginable") at baseline and following low rate and high rate stimulation. This outcome measure compared the change in intensity from baseline between low rate and high rate stimulation.
