BackgroundFibromyalgia syndrome is a chronic disease consisting of widespread pain, fatigue, sleep disturbances, and cognitive impairments, among other symptoms, which affect daily physical activity. However, the influence of functional status on physical activity involved in leisure, household and work activities has not been researched previously. The main objective was to evaluate balance, strength, spinal mobility, mechanosensitivity and function levels as related factors of physical activity in female with fibromyalgia.MethodsThirty-four patients with Fibromyalgia and 22 matched controls were included in a cross-sectional study. Dynamic and static balance, general and daily activities disability, lumbosacral mechanosensitivity, spinal range of motion, lower limb strength, physical activity in leisure, household and work activities were registered. We tested for differences between groups by using independent sample t-tests. The influence of demographics, symptoms and physical outcomes on physical activity was statistically analyzed using bivariate and multivariate regression analyses.FindingsThere was a significant association between leisure-time physical activity scores and age (r = 0.564), spinal flexion (r = 0.512), spinal extension (r = 0.421) and the total range of spinal inclination (r = 0.533). Fifty-eight percent of the variance of leisure-time physical activity was explained by age and range of spinal flexion-extension. Similarly, functional mobility was associated with physical activity at home and work scores (r = 0.459), explaining 21% of its variance.InterpretationA higher time spent in leisure, household and work activities was related to higher age, spinal range of motion and lower functional mobility in women with Fibromyalgia. Rehabilitation intervention programs should promote physical activity at home, work and leisure time.Copyright © 2018 Elsevier Ltd. All rights reserved.
