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，评估老年人跌倒风险的测试是常见的。然而，这类检测的敏感性和特异性不高，尤其是在社区老年人中。需要一种新的跌倒风险评估测试，特别是在社区居住的老年人。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。该系统需要测量的两个部分，认知方面和运动方面。认知方面的测量作为神经心理测试的成绩。根据步态参数、步速、步幅和其他参数的数据测量运动特征。为了测量新测试的这些方面，我制作了一套新的测量系统，该系统配备了步态模式测量和视觉目标的呈现。使用记忆脑成就对步态模式进行测量，这是组织所需工具系统所需要的

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.
