Resumo: BACKGROUND AND OBJECTIVES: Fibromyalgia syndrome is a chronic condition causing spontaneous widespread pain associated with hypersensitivity. This study aimed at investigating the pressure pain endurance in women with fibromyalgia syndrome to determine the range of painful stimulation that an individual with fibromyalgia syndrome can resist acceptably. METHODS: We conducted an observational, descriptive, crosssectional study with 60 subjects (51.23±8 years), who met the American College of Rheumatology/1990 (ACR) criteria for fibromyalgia syndrome, and 42 healthy volunteers (48.33±9 years) as the control group. Algometry was performed to record pressure pain detection threshold and pressure pain tolerance, and fibromyalgia impact questionnaire was used to determine the impact of fibromyalgia syndrome. Pressure pain endurance was calculated as the arithmetic difference between pressure pain tolerance and pressure pain detection threshold. RESULTS: A significant difference in fibromyalgia impact questionnaire (p<0.0001), pressure pain detection threshold, and pressure pain tolerance (p<0.0001) was found between both groups. Furthermore, a significant difference in pressure pain endurance (p<0.0001) for each of the 18 points identified by ACR was noted between both groups, with the highest range of physical stimulation observed in the control group. A correlation between pressure pain endurance and pressure pain detection threshold (r=0.8334; p<0.0001) and pressure pain tolerance (r=0.8387; p< 0.0001) was observed in the fibromyalgia syndrome group. CONCLUSION: Pressure pain endurance of the fibromyalgia syndrome group was extremely lower, when compared with that of healthy controls, and may be used as an additional component to measure the disturbance in pain perception and to determine the range of painful stimulation that an individual with fibromyalgia syndrome can acceptably resist.
