RESUMO
INTRODUCTION: Osteoarthritis is the most common joint disorder in the world and its incidence is rising, and one of the most frequent causes of pain, loss of function and disability in adults. AIM: The aim of this study was to evaluate the effects of Mat Pilates on health status, pain, stiffness, and functionality of older adult women with knee osteoarthritis (KOA). METHODS: A randomized-controlled trial to preliminarily test an intervention protocol of Mat Pilates in older women with KOA on health status, pain, stiffness, and functionality. This study included 41 volunteers with age over 40 years, which mean was 52.1 ± 8.9 years, and were allocated into Mat Pilates and control groups. The protocol was developed to be performed in 60 min, twice a week; the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Medical Outcomes Study 36 (SF-36) were used to assess pain, to evaluate functionality and stiffness. RESULTS: The Mat Pilates group significantly improved the functional capacity assessed by SF-36 (33.12 ± 22.03 to 69.37 ± 22.43, p < 0.05), and by WOMAC (29.75 ± 6.92 to 9.75 ± 9.35, p < 0.05). The pain domain also improved in Mat Pilates group assessed by SF-36 (39.50 ± 12.89 to 71.75 ± 18.66, p < 0.05) and by WOMAC (8.00 ± 2.56 to 2.75 ± 3.01, p < 0.05). The total score of WOMAC (41.75 ± 10.39 to 14.25 ± 13.88, p < 0.05), and the general health status assessed by SF-36 (59.44 ± 18.07 to 82.75 ± 12.03, p < 0.05) only improved for Mat Pilates group. No differences were observed in outcomes for the control group in both questionnaires. CONCLUSION: Our results show that Mat Pilates protocol can improve the health status, pain, and functionality of older women with KOA.
