Introdução: As dificuldades encontradas em individuos após Acidente Vascular
Encefálico, ao nível da marcha, influenciam significativamente o retorno ao trabalho, a
participação na comunidade ou o desempenho nas actividades da vida diária.
Objectivo: Neste trabalho, procurou-se verificar qual o efeito de um programa de
intervenção em fisioterapia nos ajustes posturais antecipatórios que ocorrem previamente
ao movimento voluntário e assim pré-determinar a sua contribuição para a estabilidade
postural e o equilíbrio.
Material e Métodos: Para testar os pressupostos inerentes, relatam-se dois casos
clínicos de sujeitos do sexo masculino com diagnóstico de Acidente Vascular Encefálico.
Estes foram submetidos a um programa de intervenção em fisioterapia, durante 10
semanas consecutivas, baseado no Conceito de Bobath e que teve em conta o principal
problema de cada indivíduo. Foi monitorizada a actividade electromiográfica do ventre
medial do Tibial Anterior e Solear na fase de pré-activação da marcha, em dois momentos
distintos, no início e no fim da intervenção.
Resultados: Dos resultados obtidos evidenciam-se as diferenças entre os tempos médios
de pré-activação, bem como as diferenças entre a percentagem da contracção isométrica
voluntária máxima atingida pelos músculos Tibial Anterior e Solear, direito e esquerdo,
entre os dois momentos de avaliação, em ambos os sujeitos. Verificou-se, no entanto, que
a actividade electromiográfica dos referidos músculos possui grande variabilidade.
Conclusão: Os resultados sugerem que o programa de intervenção em fisioterapia
parece ter tido influência no recrutamento da actividade muscular do TA e do SO, uma
vez que, em termos médios absolutos, ocorreram diferenças após a implementação das
estratégias e procedimentos da intervenção.
Introduction: The difficulties found in individuals after stroke, on the basis of walking independently, are a huge influence in the ability to return to work, participate in the community or perform other activities of daily living. Purpose: Whith this research, it is aimed to verify the effect of a program of physiotherapy intervention in the anticipatory postural adjustments which occur previously to the voluntary movement and by this pre-determinate its contribution to the postural stability and equilibrium. Methods and Materials: To test the inerent assumptions, it is described two clinical cases of two male individuals with stroke diagnosis. Both were submitted to an intervention program of Physioterapy, for ten consecutives weeks, based in the Bobath Concept which had in focus the main problem of the individuals. In each individual it was monitorize the electromyography activity of the Tibialis Anterior and Soleus in the phase of pre-activation of the gait, in two distinguish moments, at the beginning and at the end of the intervention. Results: From the results obtained, it is verified the diferences between the medium times of pre-activation, and also the diferences between the percentage of the maximum voluntary isometric contraction achieved by the Tibialis Anterior and Soleus muscles, right and left, between the two moments of evaluation, in both individuals. Although, it was verify that the electromiographic activity of the refered muscles, has a high variability. Conclusion: The results obtained let us suggest that the intervention in physiotherapy established seams to have influence in the muscular activity recruitement of the Tibialis Anterior and Soleus because, in absolutes medium terms, occured differences after the implementation of the procedures and strategies of the intervention.
