About this study

This study seeks to evaluate the use of intermittent dosing as an alternative paradigm for patients with DRG stimulation in place for at least 1 year and minimum 50% pain relief in the targeted area. Patients will be prospectively randomized to one of two stimulation paradigms both of which involve intermittent dosing at 30 seconds ON and 90 seconds OFF. Group 1 will have their frequency set at 20 Hz with amplitude levels adjusted in order to remain in the therapeutic window (subthreshold stimulation). Group 2 will have their frequency set at 5 Hz with amplitude levels adjusted in order to remain in the therapeutic window (subthreshold stimulation) This study will be performed in a crossover fashion, meaning patients will be changed to the alternate dosing regimen at the 13-week time period. Patients will be seen and evaluated prior to randomization and reprogramming, and thereafter evaluated at 4, 8, and 12-weeks. At the 12-week time period, patients will begin a 1-week washout period of continuous stimulation. At the 13-week time period, patients will be evaluated, crossed over to the other study arm and thereafter evaluated at 17, 21, and 25-weeks.
