Fibromyalgia is a medical disorder characterized by chronic widespread pain, a heightened and painful response to pressure. Currently no investigation is available for identifying low frequency BOLD fluctuation components during active press pain stimulation paradigm while recent study evaluated low frequency fluctuation during resting-state. Using independent components analysis (ICA) of active press pain paradigm, our results demonstrated (1) the existence of intrinsic slow fluctuation BOLD signal components during active pain stimulation paradigm and (2) the possible differences in intrinsic brain connectivity between FM patients and healthy controls.
