Effects of a functional training program in patients with fibromyalgia: A 9-year prospective longitudinal cohort study

Abstract

There are evidences that physical exercise is an effective instrument for improving physical fitness, health, and quality of life and causes beneficial effects on the symp- toms of patients with fibromyalgia. The purpose of this study was to analyze effects of a functional training program on pain, fitness, and quality of life in patients with fibromyalgia in a 9-year prospective longitudinal cohort study. Forty women with fibromyalgia participated in this study; 24 received an exercise program and were called the active group; and 16 were the control group. Tender points, visual analogi- cal scale (VAS) of pain, physical fitness, Fibromyalgia Impact Questionnaire (FIQ), and Short-Form Health Survey 36 (SF-36) were analyzed. The active group experi- enced significant improvements in FIQ, TP, and VAS (P < .001), whereas the con- trol group showed significant worsening in the FIQ scale (P = .004). Moreover, the active group experienced significant improvements in leg strength (P < .001), bal- ance (P = .033), cardiorespiratory fitness (P < .001), emotional role (P = .024), and mental health (P = .025); whereas the control group significantly worsened on hand- grip strength (P = .017), balance (P = .043), cardiorespiratory fitness (P = .020), and in general health (P < .001). A Pearson correlation analysis revealed a significant relationship between the improvement in physical fitness variables and the improve- ments in FIQ, TP, and VAS. In conclusion, a regular practice of moderate-intensity physical activity shows a positive effect long-term on fitness, pain, the impact of the disease, and the quality of life in women with fibromyalgia.
