Using Lower Amplitudes to Maintain Effective High Dose Spinal Cord Stimulation Therapy (SCS Dosing Pilot Study).

Background: Spinal cord stimulation is an effective therapy for chronic back and/or leg pain. Amplitude dose-response studies are lacking; therefore, little guidance exists regarding the minimum amplitude requirements with specific high dose parameters. This study characterized the minimum amplitude level that maintained SCS therapy satisfaction and pain relief when stimulating at 1000 Hz and 90 μsec.

Prospective, Randomized, Sham-Control, Double Blind, Crossover Trial of Subthreshold Spinal Cord Stimulation at Various Kilohertz Frequencies in Subjects Suffering From Failed Back Surgery Syndrome (SCS Frequency Study).

Introduction: The increasing use of high frequency paresthesia-free spinal cord stimulation has been associated with improved outcomes in the therapy of neuropathic pain. What is unknown is the effect of varying frequency on pain relief and the placebo effect.

Materials And Methods: This is a prospective, randomized, sham-controlled double blind crossover study.
