Abstract
The aim of this study was to compare muscle function and functionality of a group of elderly women with knee OA (GOA=15) with the asymptomatic group(GAS=18). Anthropometric characteristics, physical function and quality of life were evaluated by a specific OA questionnaire Western Ontario and McMaster Universities Osteoarthritis Index, and a battery of functional tests: Short Physical Performance Battery, Timed Up and Go Test, and the 6 minutes walking test. Kolmogrov-Smirnov test was applied to confirm data normality. To variable that showed normal distribution the student T test for independent samples was used and theU Mann-Whitney was applied to variables without normal distribution (p<0.05). The results showed that there are no differences in anthropometric variables, age, physical and functional performance between groups. It can be concluded that elderly women with mild to moderate knee OA have physical and functional performance similar to asymptomatic elderly.

Summary
Participaram do estudo 33 mulheres com idade de 66±4 anos, divididas em dois grupos: com diagnóstico de osteoartrite (GOA; n=15) e assintomáticas para OA (GAS; n= 18). Critérios de inclusão: no Grupo com Osteoartrite (GOA) foram incluídas mulheres com OA nas articulações dos joelhos uni ou bilateralmentede grau leve a moderado, diagnosticadas pelo médico por meio de exame clínico e radiográfico de acordo com os critérios do American College of Rheumatology (ALTMAN et al, 1986). A capacidade funcional das voluntárias foi avaliada por meio de uma bateria de testes padronizados e validados para a população idosa (GOMEZ et al, 2013): o Short Physical Performance Battery (SPPB), composto por 3 testes que avaliam: i) a velocidade da marcha na distância de 4 metros; ii) o equilíbrio estático nas posições de apoio bipodal, semi-tandem e tandem durante 10 segundos; iii) a força muscular dos membros inferiores pelo tempo necessário para levantar e sentar em uma cadeira 5 vezes. A pontuação das respostas varia de 0 a 4 e maiores escores indicam pior quadro de dor, rigidez ou incapacidade funcional (McCONNELL; KOLOPACK; DAVIS, 2001; FERNANDES, 2003)
