Abstract

OBJECTIVE

To examine the timed up and go (TUG) and tandem walk test (TWT) as fall prediction assessments in Thai elderly.

MATERIAL AND METHOD

Elderly subjects aged between 60 and 86 years and living in Nakhonpathom and Samutsakhon provinces were classified as fallers and non-fallers by self-report in the past six months. The TUG and TWT were used to predict falls. The optimal cutoff score and validity indexes were determined by plotting the receiver operating characteristic (ROC) curve and crosstabs analysis.

RESULTS

One hundred and sixty-one elderly subjects were classified as fallers (7 males and 43 females) and non-fallers (24 males and 87 females). The area under the curve (AUC) of ROC were 0.62 (95% CI = 0.59, 0.76; p = 0.0001) for TUG and 0.605 (95% CI = 0.514, 0.696; p = 0.033) for TWT error score. The cutoff scores were 10.5 seconds for TUG (74% sensitivity and 57.7% specificity) and five scores for TWT error (62% sensitivity and 55% specificity).

CONCLUSION

TUG and TWT error were useful tools to explain faller status in Thai community-dwelling for theelderly. TWT time was not sensitive enough to detect the elders who were at risk of falls.

摘要

目的

研究定时起立行走测试（TUG）和串联行走测试（TWT）在泰国老年人跌倒预测评估中的作用。

材料与方法

居住在佛统府和沙没沙空府的60至86岁老年受试者，根据过去六个月的自我报告分为跌倒者和非跌倒者。采用TUG和TWT来预测跌倒情况。通过绘制受试者工作特征（ROC）曲线和交叉表分析确定最佳截断分数和有效性指标。

结果

161名老年受试者被分为跌倒者（7名男性和43名女性）和非跌倒者（24名男性和87名女性）。TUG的ROC曲线下面积（AUC）为0.62（95%CI = 0.59, 0.76；p = 0.0001），TWT错误分数的AUC为0.605（95%CI = 0.514, 0.696；p = 0.033）。TUG的截断分数为10.5秒（灵敏度74%，特异度57.7%），TWT错误分数的截断分数为5分（灵敏度62%，特异度55%）。
