Previous studies pointed out that there were common tests for evaluate the fall risk in elderly people. However, the sensitivity and specificity of such kinds of tests are not high especially in the community dwelling elderly people. A new fall risk assessment test is needed especially in community dwelling elderly people. The purpose of this study was to develop a new system using the measure of cognitive load on gait. The system requires the 2 part of measurements, cognitive aspect and motor aspect. Cognitive aspect was measured as the performance for neuropsychological test. Motor aspect was measured from the data of gait parameters, gait speed, stride, and other parameters. In order to measure these aspects of new test, I made a new measuring system that equipped gait pattern measurement and presentation of visual targets. Gait patter measurement was made using membrain achievemtne r onentis needed toolosystem is needed to orpose

此前的研究指出，有一些常见的测试可以评估老年人的跌倒风险。然而，此类测试的敏感性和特异性不高，特别是对于社区居住的老年人。需要进行新的跌倒风险评估测试，特别是对于社区居住的老年人。本研究的目的是开发一种使用步态认知负荷测量的新系统。该系统需要测量两部分：认知方面和运动方面。认知方面作为神经心理学测试的表现进行测量。运动方面是通过步态参数、步态速度、步幅和其他参数的数据来测量的。为了测量新测试的这些方面，我制作了一个新的测量系统，配备了步态模式测量和视觉目标的呈现。步态模式测量是使用膜实现的，需要工具系统来实现
