Abstract

Purpose: Falls are a significant factor affecting the health of older adults and are closely related to cognitive function. Adopting an effective method to evaluate the risk of falls in older adults is essential for improving their healthcare. This study combined cognitive and motor functions to determine a reliable probe reaction time during water-carrying walking.
Patients and Methods: We divided 100 community-dwelling older adults (aged 65 years and over) into two groups according to their fall history: the fall group and no-fall group. All subjects were tested on fall tasks using the timed up-and-go (TUG) test, 10-m walk timing test, trail marking test part-A (TMT-A), and water-carrying walking probe reaction time (P-RT).
Results: The fall group showed slower walking speeds and longer TUG, TMT-A, and P-RT times than the no-fall group. In the logistic regression analysis with falls as the dependent variable, water-carrying walking P-RT was identified as a useful factor, and the cut-off value of the water-carrying walking P-RT was 454 ms, which was evaluated using the receiver operating characteristic curve.
Conclusion: The P-RT of the water-carrying walking test was found to be credible and useful for evaluating the fall risk in older adults. Therefore, it is recommended that the P-RT-based dual-task be used as a predictive indicator of future falls in the older population.

Keywords: falls, probe reaction time, older adults, dual task

根据提水行走时的探头反应时间评估老年人跌倒风险

目的跌倒是影响老年人健康的一个重要因素，与认知功能密切相关。采用一种有效的方法来评估老年人跌倒的风险对于改善他们的医疗保健至关重要。本研究结合了认知功能和运动功能，以确定在拎水行走过程中可靠的探头反应时间：我们根据跌倒史将 100 名居住在社区的老年人（65 岁及以上）分为两组：跌倒组和未跌倒组。所有受试者都接受了跌倒任务测试，包括定时起立行走（TUG）测试、10 米步行计时测试、步道标记测试 A 部分（TMT-A）和提水步行探针反应时间（P-RT）：结果：与未跌倒组相比，跌倒组的步行速度较慢，TUG、TMT-A 和 P-RT 时间较长。在以跌倒为因变量的逻辑回归分析中，运水行走 P-RT 被认为是一个有用的因素，运水行走 P-RT 的临界值为 454 毫秒，该值使用接收器操作特征曲线进行评估：结论：研究发现，背水行走测试的 P-RT 可信且有助于评估老年人的跌倒风险。因此，建议将基于P-RT的双重任务作为老年人群未来跌倒的预测指标。关键词：跌倒；探针反应时间；老年人；双重任务

期刊介绍： Clinical Interventions in Aging, is an online, peer reviewed, open access journal focusing on concise rapid reporting of original research and reviews in aging. Special attention will be given to papers reporting on actual or potential clinical applications leading to improved prevention or treatment of disease or a greater understanding of pathological processes that result from maladaptive changes in the body associated with aging. This journal is directed at a wide array of scientists, engineers, pharmacists, pharmacologists and clinical specialists wishing to maintain an up to date knowledge of this exciting and emerging field.
