BACKGROUND AND OBJECTIVES: Osteoarthritis (OA) is one of the most prevalent rheumatic diseases in the elderly, being a frequent cause of incapacity among this population. It is more common in the knee and is characterized by pain, stiffness and function loss. Conventional physiotherapy, through the training of muscle strength, is described as a satisfactory method to improve functional limitations of such individuals. Wii therapy, through the use of Nintendo's wii videogame and the wii fit platform, is being used as therapeutic resource for the rehabilitation of patients with musculoskeletal diseases. This study aimed at comparing the effects of conventional physiotherapy and wii therapy on pain, stiffness, functional incapacity and balance of elderly women with knee OA. METHODS: Sample was made up of 71 women with knee OA and users of a support group for the elderly from the city of Passo Fundo-RS, being 33 (Group I) submitted to conventional physiotherapy and 38 (Group II) submitted to wii therapy. Evaluated parameters were pain, stiffness and functional incapacity through The Western Ontario and McMaster Osteoarthritis Index (WOMAC) questionnaire, and balance through Berg Balance Scale. RESULTS: Elderly women submitted to conventional physiotherapy (group I) have presented, as compared to wii therapy (group II), lower pain scores (11.05 ± 8.15 versus 19.24 ± 16.96; p = 0.00) and incapacity (12.42 ± 7.91 versus 17.42 ± 14.08; p = 0.06) after intervention. Stiffness (25.13 ± 15.99 versus 14.39 ± 17.43; p = 0.00) and balance (50.94 ± 1.45 versus 53.45 ± 5.16; p = 0.00) scores were better for patients submitted to wii therapy, with statistical significance in both items. CONCLUSION: Wii therapy was better to improve stiffness and balance in elderly women with osteoarthritis as compared to conventional physiotherapy.
