The motor deficits caused by Parkinson's disease are not able to block adjustments for a safe strategy during obstacle crossing in individuals with moderate disease

Abstract The aim of this study was to verify whether patients with Parkinson's disease (PD) are able to adjust their motor behavior according to restrictions imposed by the task instruction during walking with obstacle crossing. Eighteen elderly people (moderate motor compromise) with a diagnos...

Description
Summary:Abstract The aim of this study was to verify whether patients with Parkinson's disease (PD) are able to adjust their motor behavior according to restrictions imposed by the task instruction during walking with obstacle crossing. Eighteen elderly people (moderate motor compromise) with a diagnosis of PD walked on a pathway and cross an obstacle according to the following conditions: walking at preferred velocity; walking at maximum vertical elevation of the feet to cross the obstacle; walking at maximum step length to cross the obstacle; walking at maximum velocity. The modulations were directly related to the instructions provided to patients with PD before performing each task, which seems to indicate that attentional cues can influence and benefit strategies during obstacle crossing. In conclusion, patients with PD are able to adjust walking during obstacle crossing according to instructions given to them, which increases their safety. Resumen El objetivo de este estudio fue verificar se los pacientes con enfermedad de Parkinson (EP) son capaces de modular el comportamiento motor de acuerdo con restricciones impuestas por la instrucción en la tarea de sobrepasar un obstáculo. Dieciocho adultos mayores con diagnóstico de EP (con deficiencia motora moderada) caminaran sobre una pasarela e sobrepasaran un obstáculo de acuerdo con las siguientes instrucciones: velocidad preferida; elevación máxima del pie para sobrepasar el obstáculo, máxima distancia del paso para sobrepasar el obstáculo; sobre pasada máxima velocidad. Las modulaciones realizadas están directamente relacionadas a las instrucciones dadas a los pacientes antes de la realización de cada tarea, lo que indica que pautas auditivas pueden influenciar e beneficiar las estrategias utilizadas. A través de este estudio se puede concluir que pacientes con EP son capaces de modular la sobrepasada de obstáculo de acuerdo con la instrucción que les es dada, lo que aumenta la seguridad en la tarea. Resumo O objetivo deste estudo foi verificar se pacientes com doença de Parkinson (DP) são capazes de modular o comportamento motor de acordo com restrições impostas pela instrução na tarefa de ultrapassagem de obstáculo. Dezoito idosos com diagnóstico de DP (comprometimento motor moderado) andaram sobre uma passarela e ultrapassaram um obstáculo de acordo com as seguintes instruções: velocidade preferida; elevação máxima do pé para ultrapassagem do obstáculo; máximo comprimento do passo de ultrapassagem; ultrap
