Resumo: | This study was conducted to primarily assess the differences between peak torque and work done by the flexor and extensor muscles in normal and in osteoarthritic knees. In addition, factors which might attenuate muscle torque were investigated. A group of eleven OA patients was studied. Twelve elderly asymptomatic subjects of the same age were used as a control group. The WOMAC OA index was employed to assess clinical knee joint function. I*hc parameters of muscle strength were obtained by the LIDO Active Isokinetic Rehabilitation System. The speed of the isokinetic concentric contraction was set at 60 degress/second. Independent Student t-tests were carried out to test differences between groups. Person product moment correlation coefficients were calculated to investigate association between the variables. The OA group presented a significant decrease in muscle torque and total work done by both flexor and extensor muscles. The decrease in the extensor peak torque and in the work done by the extensor muscles was greater than that observed in the flexor muscles. Pain and stiffness accounted for isokinetic torque differences in OA kness. There was no close relationship between age or the grade of X-ray change and the peak torque and work measures. |

Além disso, fatores que poderiam atenuar a força muscular como idade, alterações clinicas e radiológicas foram avaliados. Um grupo de onze pacientes portadores de Osteoartríte (OA) foram avaliados. Doze assintomáticos indivíduos da mesma faixa etária foram utilizados como grupo controle. O índice OAWOMAC foi utilizado para avaliar o status clínico da articulação do joelho. Os parâmetros de força muscular foram obtidos através do sistema de Reabilitação isocinético-LIDO. A velocidade de contração concêntríca isocinética foi selecionada para 607s. Teste-t de "Student" para grupos independentes foi utilizado para examinar as diferenças entre os grupos. Coeficientes de correlação de "Pearson" foram calculados para investigar associação entre as variáveis. O grupo com OA apresentou uma redução significativa tanto do torque muscular quanto do trabalho realizado pelos músculos flexores e extensores do joelho. A redução do torque extensor e do trabalho extensor foi maior que a apresentada pelos músculos flexores. A dor e a rigidez articular apresentaram-se como principais determinantes das diferenças de torque e trabalho isocinéticos em pacientes com OA. Não houve interferência de fatores como idade e alterações radiológicas no declínio das medidas de força muscular.Universidade de São Paulo.
