Yoo Y, et al. - Assuming that transcranial direct current stimulation (tDCS) targeting the dorsolateral prefrontal cortex or the occipital nerve (ON) is a noninvasive neuromodulation technique capable of improving fibromyalgia symptoms, researchers examined the effect of combining 2 targets of stimulation using tDCS. ON-tDCS in isolation or coupled with pre-ONS right-anode bifrontal tDCS was applied and its effect on fibromyalgia was assessed using the Fibromyalgia Impact Questionnaire, the Beck Depression Inventory, and Numeric Rating Scale for pain scores. Findings suggest that adding right-anode bifrontal tDCS to ONS has no added benefit in improving fibromyalgia-related symptoms.
