Abstract

The main aim of this work was to identify an experimental method for the quantitative assessment of the motor performance of elderly people, during motor tasks requiring also different cognitive efforts. Specifically, a dual task approach was used to investigate age-related deficits in the ability to walk or climb stairs, and to concurrently perform various categories of cognitive tasks. A wearable biomechatronic system was used to measure the kinematics of the lower limb, during the task execution. Parameters derived from gait analysis were used for the quantitative assessment of examined subjects motor performances. Preliminary results showed that the proposed method can provide accurate and reliable measurements, which could be useful to deep inside the comprehension of the age-related deficits of lower limb motor control strategies.
基于可穿戴生物机电系统的下肢运动控制策略的年龄相关性改变分析
这项工作的主要目的是确定一种定量评估老年人运动表现的实验方法,在运动任务中需要不同的认知努力。具体来说,双任务方法被用于研究与年龄相关的行走或爬楼梯能力缺陷,以及同时执行各种类型的认知任务。在任务执行过程中,使用可穿戴生物机电系统测量下肢的运动学。步态分析得出的参数用于定量评估被试的运动表现。初步结果表明,该方法能够提供准确可靠的测量结果,有助于深入了解与年龄相关的下肢运动控制策略缺陷。
