About

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.

Full description

The Quell is battery powered with rechargeable batteries and is strapped to participant's upper calf with a velcro band. It has been cleared by the FDA for safety. It is designed to improve fibromyalgia by the principles of transcutaneous electrical stimulation of nerves much like a traditional transcutaneous electrical nerve stimulator (TENS) unit. Investigators expect to enroll approximately 130 subjects in this study. Participants will be equally randomized to one of two experimental groups: High Frequency Quell group (N=65) or Low Frequency Quell group (N=65). This study hopes to find out whether low frequency or high frequency stimulation is most useful among persons with fibromyalgia.
