Resumo

O presente estudo analisou o stiffness dos membros inferiores de um hemiparético mediante aplicação de estimulação elétrica. Foi avaliado um indiví­duo hemiparético de 39 anos e sexo masculino. A Escala de Ashworth Modificada (EAM) pontuou clinicamente a hipertonia e o aparelho isocinético Cybex Norm mensurou os torques dos membros inferiores. Utilizou-se um protocolo de 30 minutos de estimulação com um Endophasys R ajustado no limiar sensorial, freqüência modulada de 2500Hz e freqüência de pulso de 20Hz. A avaliação foi realizada antes e imediatamente após o protocolo. A EAM pontuou 3 tanto antes como após a intervenção.O teste isocinético detectou redução do stiffness após uso da corrente com destaque para os torques extensores na velocidade de 90o/s (p < 0,005). Estes resultados se assemelham í queles obtidos em outros estudos, embora apresentem discrepâncias nas metodologias. A estimulação elétrica parece ser um potente adjuvante na reeducação de indiví­duos comalterações no controle motor.
