Prospective Evaluation of RINCE to Reduce Fibromyalgia Effects - St. Joseph Mercy Oakland

The purpose of this study is to test the safety and efficacy of a noninvasive cortical electrostimulation therapy known as "Reduced Impedance Noninvasive Cortical Electrostimulation" (RINCE) in the management of fibromyalgia. Patients who meet the 1990 American College of Rheumatology criteria for fibromyalgia will receive up to 24 RINCE treatments delivered by a medical device called "NeuroPoint". Approximately 45 fibromyalgia patients will be randomized into one of three study groups. One of these groups will receive sham treatment, meaning they will receive no treatment at all, while the remaining two groups will receive different amounts of RINCE therapy. The study's primary outcome measure will be the patient's change from baseline in self-reported 24-hour average pain intensity. The study's hypothesis is that there will be a difference between treatment groups in primary outcome measure.
