Study Summary

A randomized controlled with cross over study compares efficacy of burst stimulation, 1000 hertz stimulation, and standard stimulation in an non-superiority trial. The study duration is approximately 24 weeks and each stimulation modes will last for approximately 3 weeks with approximately 4 days of wash off in between.

Eligibility Criteria

Inclusion

Inclusion Criteria:

Subject must be 18 years and older, and younger than 75 years of age.

Subject continues to receive adequate pain relief with greater than or equal to 50%pain relief based on pre-trial and pre-implant pain assessment.
Device age should not be less than 2 months old.
Subject is willing to comply with all requirements of the study.

Exclusion

Exclusion Criteria:

Subjects who are getting <50% pain relief on current SCS based on pre-trial andpre-implant pain assessment.

Study Description

Study will enroll 22 patients for the purpose of evaluation of efficacy of burst stimulation, 1000 hertz frequency stimulation or standard stimulation in patients who have a spinal cord stimulators implanted. Each patients will be randomized to either group A or B, where each groups consists of Burst, standard, and 1000 hertz frequency stimulation or vice versa with wash off period in between. The duration for each stimulation modes will be approximately 3 weeks, with approximately 4 days of wash off prior to starting the new stimulation mode and in between stimulation modes. Treatment duration for each groups will last about 3 months or less, and with cross over total duration of the study is about 6 months in total.

During the trial there will be 13 visits. The first visit will consist of screening visit activities and once the eligibility of the subjects are confirmed, they will be randomized and they can start the study immediately and begin their wash off period. After the initial visit/ randomization visit, there will be 12 follow up visits. At each visit, patients will be assessed for their pain, disability index, and their perception of their painful condition, as well as any adverse events and changes of medication usage or lack there of. At the end of the study, the data will be pooled to look at the pain level, disability index, and patients perceived changes in their painful condition for each treatment groups (Burst stimulation, 1000 hertz stimulation and standard stimulation) to determine if subject experienced equivocal pain relief from all three stimulation modes.
