Electrophysiological Findings in Fibromyalgia Patients

"Sympathetic skin response(SSR) was studied with upper and lower extremity hand and foot recording of all participants, and amplitude and latency values will be recorded. SSR measurement will be made at room temperature of 25 ºC, while the patients are resting in the supine position. 6 mm silver disc electrodes will be used as the recording electrode.~The relationship between the patients' vitamin D levels and inflammatory response markers and their sympathetic skin responses will be investigated by statistical analysis."
