Neurophysiology of Fibromyalgia

Brief Summary

Fibromyalgia is a syndrome associated with fatigue and chronic pain, leading to significant physical limitations and impaired quality of life. There are several challenges that complicate the diagnosis and management of fibromyalgia. The etiology is not well defined, as there are several proposed factors that may trigger the genesis of pain in fibromyalgia including physical and/or emotional life stressors, and genetic predispositions involving neuromodulator pathways. Chronic pain in fibromyalgia arises in the absence of tissue pathology, and consequently a lack of consensus on reliable diagnostic criteria. Understanding the neurophysiology of fibromyalgia would aid in the discovery of objective biomarkers for diagnosis. Therefore, the goals of this study are to: 1. Compare the neurophysiological responses in fibromyalgia compared to healthy controls. 2. Determine whether a two-week cTMS protocol will alter pain in individuals with fibromyalgia.
