Prospective Evaluation of RINCE to Reduce Fibromyalgia Effects - 301

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 treatment of pain associated with fibromyalgia. Patients who meet the 2010 American College of Rheumatology criteria for fibromyalgia will receive up to 24 RINCE treatments delivered by a medical device called "NeuroPoint". Approximately 200 fibromyalgia patients will be randomized into one of two study groups. One of these groups will receive sham treatment, meaning they will receive no treatment at all, while the other group will receive active RINCE treatment. The study's primary outcome measure will be the difference between active and sham treatment groups in the mean change from baseline in patients' weekly worst pain scores. The study's hypothesis is that there will be a difference between treatment groups in primary outcome measure.
