Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is designed for patients with primary fibromyalgia (FM) pain. The overall aim of the study is to determine the effect of the high frequency Quell device to manage FM compared with a low frequency device. Investigators hypothesize that those assigned to using the high frequency Quell device will report reduced pain compared with those using the low frequency Quell device; with those using the high frequency device also showing more improvement in sleep, mood, and level of activity. Investigators also hypothesize that frequency of using the Quell (increased tolerability and adherence) will be correlated with greater reduction in pain.
