三种功能性移动能力测试工具对预测老年人跌倒危险有效性的比较

摘要

目的:比较三种功能性移动能力测试工具在预测老年人跌倒危险方面的有效性.方法:116名老年人受试者参与本研究并分为跌倒组和非跌倒组.对受试者进行5次坐到站测试(five times sit to stand test,FTSST)、3m计时起立行走测试(timed up and go test,TUGT)和计时10m步行测试(timed 10-meter walk test,TWT).结果:跌倒组和非跌倒组的受试者在FTSST、TUGT和TWT之间的比较有显著差异(P＜ 0.001).Spearman相关分析结果均显示FTSST、TUGT和TWT与跌倒史之间显著相关(P＜ 0.001).Logistic回归分析显示FTSST、TUGT和TWT的时间与跌倒危险显著关联(OR:1.1643-1.2503).接受者操作特征(ROC)曲线下的面积比较FTSST、TUGT和TWT之间无显著性差异(P＞0.05),并且三种测试工具可以显著预测跌倒危险(AUC:0.68--0.73,P＜0.001).结论:FTSST、TUGT和TWT作为简便、快捷的功能性测试工具可以有效预测老年人跌倒危险.%Objective: To examine comparative validity of three functional mobility tests for predicting falls in older people. Method: One hundred and sixteen volunteers were recruited and divided into two groups: fall group and no-fall group. All subjects were tested by five times sit to stand test (FTSST), timed up and go test (TUGT) and timed 10-meter walk test (TWT). The data were analyzed by using the statistic descriptive, Spearman's correlation coefficient, Logistic regression analysis and receiver operating characteristic (ROC) curve analysis.rnResult: The fall group showed higher FTSST time(s), TUGT time(s) and TWT time(s) than the no-fall group (P < 0.001). There were significantly correlation of the FTSST time, TUGT time and TWT time with history of falls (P< 0.001). The Logistic regression analysis revealed that the FTSST, TUGT and TWT were significantly related to falling (OR: 1.1643-1.2503). The area under the receiver operating characteristic (ROC) curve for the FTSST, TUGT and TWT showed an indicator of discriminatory power was 0.68-0.73(P<0.001), and compared the area under the ROC curves of these tests there was no significant difference (P > 0.05).rnConclusion: The FTSST, TUGT and TWT as a quick, easily functional testing tool is useful for predicting falls in older people.
