A Prospective Evaluation of RINCE to Reduce Fibromyalgia Effects - University of Michigan

The purpose of this study is to evaluate the mechanisms of 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 20 patients will receive a combination of active and inactive (sham) therapy treatments over a 16-week period followed by a 4 week post-treatment evaluation. Patients will also undergo three (3) functional brain imaging scans while participating in the study: the first prior to the commencement of treatment, another mid-treatment; and the third at the completion of the treatment period. The study's primary outcome measure will be the change from baseline in self-reported 24-hour average pain intensity. The study's hypothesis is that there will be a change in pain intensity as well brain functioning. We do not expect there to be a statistically significant improvement in pain intensity due to the small sample but do expect to see statistically significant changes in cortical function as measured by EEG and fMRI
