Uma avaliação acerca do perfil somatossensorial de indivíduos hemiparéticos

Abstract

RESUMOO objetivo do presente estudo foi avaliar o perfil somatossensorial de 18 indivíduos hemiparéticos espásticos vitimados de acidente vascular cerebral com e sem bloqueio visual. Como estratégia metodológica foram utilizados os testes de contração isométrica máxima para os músculos flexores e extensores do quadril, flexores e extensores do joelho e flexores plantares além de número de ciclos por minuto em bicicleta ergométrica, que foram realizados em dois instantes: olhos abertos e olhos fechados. Após análise estatística foi comprovado diferenças significativas entre os dois momentos para cada teste. Desta forma, pode-se concluir que parece haver falhas de comunicação entre os mecanismos neurais sensório-motores para a elaboração do ato motor voluntário dos indivíduos avaliados.

Maximal isometric contraction test was used for flexor and extensor muscles of the hip and knee, and flexor plantar muscles. The number of cycles per minute on stationary bike was also measured with eyes opened and closed. Significant differences were found suggesting the existence of miscommunication between sensory-motor neural mechanisms responsible for voluntary motor actions in these individuals.

Relationship between postural control in upright stance and virtual reality in post-stroke individuals

“…The resulting deficits in motor capacity in poststroke individuals resulting from the injury in regions responsible for the processing of sensorimotor information determine variable disabilities depending on their extension, which can be characterized by changes in voluntary motor control with paralysis or paralysis of the contralateral side of the lesion (hemiplegia or hemiparesis) [6,7]. Hemiparesis is the most common clinical resulting from a post-stroke and the motor act in this condition is hampered by muscle weakness, sensory deficits, spasticity, synergistic movements, selective movements, loss of balance and deficits in postural maintenance [7].…”
