Long-Term Outcomes in Fibromyalgia Patients Treated with Cortical Electrostimulation
To evaluate long-term outcomes of a noninvasive cortical stimulation technology in the treatment of fibromyalgia (FM).
After trial follow-up survey of subjects who had completed a randomized, controlled, double-blind study of noninvasive cortical stimulation therapy some 45 months previously.
Patients with FM (N=69) who participated in the previous study, 39 of whom were mailed surveys.
Main Outcome Measure
Changes in the Fibromyalgia Impact Questionnaire.
There was a 64% survey return rate. The total Fibromyalgia Impact Questionnaire score was 52.6 at baseline, 35.7 at end of study, and 31.8 at follow-up (P<.001). Subjects reported symptom improvements lasting at least 2 years, with a reduction or elimination of medicine use and need to see physicians for FM.
A high percentage of patients with FM treated with noninvasive cortical stimulation continued to experience worthwhile improvement at follow-up.
