Development of a new fall risk assessment system in the elderly using the measure of cognitive load on gait

以前的研究指出，有一些常见的测试来评估老年人的跌倒风险。然而，这类检测的敏感性和特异性都不高，特别是在社区居住的老年人中。需要一种新的跌倒风险评估试验，特别是在社区居住的老年人中。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。该系统需要两部分测量，认知方面和运动方面。认知方面作为神经心理测试的表现。运动方面通过步态参数、步态速度、步幅等参数测量。为了测量这些方面的新测试，我做了一个新的测量系统，配备步态模式测量和视觉目标的呈现。步态模式的测量是利用脑膜成像技术来实现的，需要系统对其进行校正

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.
