本研究的目的是研究跌倒与生理因素之间的关系，主要是脚趾间隙力和Good Walker's指数。362例65岁以上老年人进行了5类步行能力和生理测试，包括10米步行时间、最大步长（MSL）、40/20 cm步长测试和串联步态，即趾间隙力和良好步行者指数。问题涉及人口统计学特征、日常生活工具活动（IADL）、主观幸福感、长期护理需求和跌倒特征。90名参与者（24.9%）报告在过去一年内跌倒一次或多次。结果显示，较低的脚趾间隙力和较低的良好步行者指数得分与跌倒显著相关。跌倒者在脚趾间隙力R、10米步行时间和最大步力方面得分较低。Good Walker’s Index与所有测试指标均显著相关。路径分析模型揭示了Good Walker's Index和跌倒之间的联系。趾隙力和Good Walker's Index可以作为社区独立生活老年人的有效预测因素。本研究提供了良好步行者指数、足间隙力与跌倒、视力与跌倒等生理因素之间相互关系的模型。
The aim of this study is to investigate the association between falls and physiological factors primarilly the toe-gap force and the Good Walker's Index using a path analysis. Three hundred and sixty-two (362) elderly people, over 65 years of age, undertook five types of walking ability and physiological tests, The Toe-gap Force and the Good Walker's Index, which consists of 10-m walking time, Maximal Step Length (MSL), 40/20 cm step test, and tandem gait. Questions concerning demographic characteristics, instrumental activities of daily living (IADL), subjective well-being, long-term care needs, and characteristics of falls were asked. Ninety participants (24.9%) reported one or more falls within the past year. The results showed that a lower toe-gap force and a lower good-walker's Index score were significantly associated with falls. Fallers scored worse on Toe-gap force R, 10-m walking time, and Maximal Step strength. The Good Walker's Index was significantly associated with all test measures. The path analysis model revealed the association between the Good Walker's Index and falls. Toe-gap force and the Good Walker's Index can serve as an effective predictive factor for older people who are living independently in the community. This study provided a model of the inter-relationships among physiological factors such as the Good walker's Index, Toe-gap force and falls, as well as vision and falls.
