ATLANTA -- Electrodes placed on the scalp to deliver weak, high-frequency currents significantly reduced symptoms of fibromyalgia in a double-blind, sham-controlled trial, a researcher said here.
Mean decline from baseline in Fibromyalgia Impact Questionnaire (FIQ) scores after 11 weeks of treatment was 15.5 points (95% CI 8.7 to 22.3) -- about a 25% drop -- compared with a 5.6-point decline (95% CI 0.1 to 11.2) in patients receiving sham treatment (P=0.03 between groups), said Jeffrey Hargrove, PhD, of Kettering University in Flint, Mich.
"Compared to sham treatment, NICE [noninvasive cortical electrostimulation] yielded clinically significant improvements in pain, tenderness, and other typical features of fibromyalgia," Hargrove told attendees during an oral presentation at the American College of Rheumatology's annual meeting here.
