Investigating practice strategies to improve dual-task performance during gait

步态一度被认为是一种几乎没有认知输入的自动运动任务，直到最近几十年，我们才开始意识到认知功能对运动控制的影响。双重任务研究范式被设计用来阐明认知如何影响姿势、地面行走以及障碍行走。认知功能在运动控制中的作用不再受到质疑，事实上，一些研究人员提出，双重任务表现的训练可能会帮助某些人群，例如有跌倒风险的老年人。

At one time gait was primarily thought of as an automatic motor task with little cognitive input, it is only in the last few decades that we have come to realize the impact of cognitive function on locomotor control. Dual-task research paradigms have been designed to elucidate how cognition influences posture, overground walking as well as obstructed walking. The role of cognitive function in locomotor control is no longer questioned and in fact, some researchers have suggested that training for dual-task performance may assist some populations, e.g. older adults at risk of falling.
