Resumen

El objeto de este trabajo ha sido evaluar el costo que produce una segunda tarea concurrente de discriminación y toma de decisiones (DTC), sobre los parámetros cinemáticos y la estabilidad dinámica de la marcha. Han participado 14 hombres y 14 mujeres, todos ellos adultos jóvenes sanos y sin patologías motoras y/o cognitivas. Se ha utilizado un diseño intragrupo de medidas repetidas donde cada participante debía de realizar una marcha normal y otra con tarea concurrente ejecutiva. Para la evaluación de los parámetros cinemáticos del ciclo de marcha se han utilizado técnicas fotogramétricas 3D y para el análisis de la cadencia y la variabilidad del paso se ha utilizado el pasillo de marcha GAITRite. Los resultados han constatado que la realización de la tarea concurrente propuesta tiende a reducir el tiempo de la fase monopodal de los dos pasos del ciclo de marcha y, especialmente, sus respectivas longitudes, siendo la  longitud de paso la principal causa de la reducción del 2% de la velocidad de desplazamiento del CG. La variabilidad del tiempo de paso y de sus respectivas longitudes se ha incrementado por efecto de la tarea concurrente propuesta. No han existido diferencias entre las medias de los factores relacionados con la estabilidad dinámica. Se sugiere utilizar un diferencial de DTC entre personas con déficit de recursos motores y/o cognitivos, con respecto a las personas en plenitud de recursos.
