Burst Optimized Stimulation Study
Burst Optimized Stimulation Study
This purpose of this study is to evaluate the therapeutic efficacy of burst microdosing
 stimulation paradigms in patients with chronic pain.
This is a prospective, multicenter, randomized, double-blinded crossover study designed to
 compare conventional burst stimulation parameters to two different burst microdosing
 paradigms.

 Subjects will be randomized 1:1:1 to one of the three groups. Each group will evaluate all 3
 stimulation paradigms in different order.

 for controlling chronic intractable pain associated with back and/or leg pain;

 -  Subject has been exclusively using burst stimulation for at least three months;

 -  Subject is 18 years of age or older;

 -  Subject's pain-related medication regimen was stable in the 4 weeks prior to the
 screening evaluation;

 -  Subject agrees not to add or increase pain-related medication from enrollment through
 the study duration;

 -  Subject is willing to cooperate with the study requirements including compliance with
 the regimen and completion of all office visits;

 Exclusion Criteria:

 -  Subject is currently participating in a clinical investigation study that includes an
 active treatment arm;

 -  Subject is currently receiving, applying or considering seeking workers compensation,
 or is involved in disability litigation;
