Outcomes of a Multicenter, Prospective, Crossover, Randomized Controlled Trial Evaluating Subperception Spinal Cord Stimulation at ≤1.2 kHz in Previously Implanted Subjects.

ABSTRACT:

Objective

The WHISPER randomized controlled trial (RCT) evaluates safety and clinical effectiveness of subperception spinal cord stimulation (SCS) at ≤1.2 kHz in subjects previously implanted with an SCS system for treatment of chronic, neuropathic pain.

Methods

WHISPER is a prospective, multicenter RCT with a crossover design sponsored by Boston Scientific, Marlborough, MA (ClinicalTrials.gov: NCT02314000). Eligible subjects were randomized (N = 140) to receive subperception or supraperception for three months and then crossed over to receive the alternative. Upon completion of crossover period, subjects who preferred subperception were followed up to one year. Overall pain, quality-of-life, and other outcomes were collected in the study. The primary endpoint was the overal
