Abstract [en]

Background: Fibromyalgia (FM) is characterized by persistent widespread pain, increased pain sensitivity and tenderness. Women with FM also report disability, in terms of negative consequences on activities of daily living. Our recent randomized controlled trial (RCT) is the first study of resistance exercise to show positive effects on pain disability. The resistance exercise program of our RCT emphasized active involvement of participants in planning and progression of the exercise, using the principles of person-acenteredness, to support each participants ability to manage the exercise and the progress of it. The aim of this sub-astudy was to investigate explanatory factors for reduced pain disability in women with FM participating in a 15-aweek person-acentered progressive resistance exercise program. Methods: A total of 67 women with FM were included in this sub-astudy of an RCT examining the effects of person-acentered progressive resistance exercise performed twice a week for 15 weeks. Tests of physical capacity and health-arelated questionnaires were assessed at baseline and after the intervention period. Multivariable stepwise regression was used to analyze explanatory factors for improvements in pain disability. Results: Reduced pain disability was explained by higher pain disability at baseline together with decreased fear avoidance beliefs about physical activity (R-2 = 28, p = 0.005). The improvements in the disability domains of recreation and social activity were explained by decreased fear avoidance beliefs about physical activity together with higher baseline values of each disability domain respectively (R-2 = 32, p = 0.025 and R-2 = 30, p = 0.017). The improvement in occupational disability was explained by higher baseline values of occupational disability (R-2 = 19, p = 0.001). Conclusion: The person-centered resistance exercise intervention, based on principles of self-efficacy, had a positive effect on recreational, social and occupational disability. The reduced pain disability seemed to be mediated by decreased fear avoidance beliefs. Age, symptom duration, pain intensity, and muscle strength at baseline had no explanatory value for reduced pain disability, indicating that the person-centered resistance exercise program has the potential to work for anyone with FM who has interest in physical exercise.
