Objective: To investigate perceived exertion at work in women with fibromyalgia. Design: A controlled cross-sectional multi-centre study. Subjects and methods: Seventy-three women with fibromyalgia and 73 healthy women matched by occupation and physical workload were compared in terms of perceived exertion at work (0-14), muscle strength, 6-min walk test, symptoms rated by Fibromyalgia Impact Questionnaire (FIQ), work status (25-100%), fear avoidance work beliefs (0-42), physical activity at work (7-21) and physical workload (1-5). Spearmans correlation coefficient and linear regression analysis were conducted. Results: Perceived exertion at work was significantly higher in the fibromyalgia group than in the reference group (p=0.002), while physical activity at work did not differ between the groups. Physical capacity was lower and symptom severity higher in fibromyalgia compared with references (pless than0.05). In fibromyalgia, perceived exertion at work showed moderate correlation with physical activity at work, physical workload and fear avoidance work beliefs (r(s) = 0.53 0.65, pless than0.001) and a fair correlation with anxiety (r(s) = 0.26, p=0.027). Regression analysis indicated that the physical activity at work and fear avoidance work beliefs explained 50% of the perceived exertion at work. Conclusion: Women with fibromyalgia perceive an elevated exertion at work, which is associated with physical work-related factors and factors related to fear and anxiety.
