Open Access Abstract Dysregulated psychophysiological responses have been observed in patients with fibromyalgia syndrome FMS although the results are inconsistent. Surface electromyographic EMG systolic and diastolic blood pressure heart rate HR and skin conductance levels SCLs were continuously recorded at baseline and during a series of stress and relaxation tasks in 90 FMS patients and 30 age and sex matched healthy controls HCs . The patient sample demonstrated lower baseline EMG levels compared to the HCs on all tasks. In contrast the patients displayed elevated HR and SCL sympathetic vasomotor and sudomotor indices respectively during both stress tasks. A cluster analysis identified four psychophysiological response patterns 63.3 of HCs showed increased muscle tension and stable cardiovascular responses 34.8 of FMS patients showed a pattern of increased sympathetic vasomotor reactivity with stable sudomotor and reduced .
