Clinical Trial Summary

The purpose of this study is to evaluate and compare the therapeutic efficacy of intermittent Dorsal Root Ganglion Stimulation (DRG-S) to standard continuous stimulation in patients with chronic intractable pain

Description:

Intermittent Dorsal Root Ganglion Stimulation (DRG-S) dosing consists of preprogrammed cycles during which stimulation is delivered with standard DRG-S parameters alternated with periods during which no stimulation is being delivered. In this study the investigators propose to evaluate therapeutic efficacy of Intermittent DRG-S at 1 minute on: 1 minute off and 1 minute on: 2 minute off dosing in comparison to standard continuous DRG-S dosing and determine if there is noninferiority between the intermittent and continuous paradigms in chronic pain patients with permanent DRG-S implants.
