To compare the ability of Timed Up and Go (TUG) and usual gait speed (UGS) to predict incident disability completing basic activities of daily living (ADL) and instrumental ADL (IADL) in older adults free of disability at baseline, and to provide estimates for the probability of incident disability at different levels of baseline mobility performance.
Data from the first 2 waves of The Irish Longitudinal Study on Ageing, a study assessing health, economic, and social aspects of ageing in adults aged ≥50 years.
A nationally representative, population-based sample of community-dwelling adults.
Participants aged ≥65 years who completed mobility tests during a health assessment, had no reported difficulty in ADL/IADL, and had a Mini-Mental State Examination score ≥24 were re-interviewed after 2 years (n=1664).
Not applicable.
Participants completed the TUG and UGS at baseline and indicated difficulty in a number of basic ADL and IADL at follow-up.
Receiver operating characteristic analysis indicated that TUG and UGS are acceptable tools to predict disability in ADL and IADL (area under the curve [AUC]=.65-.75) with no significant difference between them (P>.05). Both were excellent predictors of difficulty in higher-level functioning tasks such as preparing hot meals, taking medications, and managing money (AUC>.80). Predictive probabilities were obtained across a range of performance levels.
TUG and UGS have similar predictive ability in relation to incident disability in basic ADL and IADL. Predictive probabilities can be used to identify those most at risk and in need of particular services. Since improving physical function can prevent or delay dependence in ADL/IADL, TUG and UGS can also provide performance goals and feedback during exercise interventions.
比较定时起立行走测试（TUG）和常规步速（UGS）预测基线时无残疾的老年人出现完成基本日常生活活动（ADL）和工具性日常生活活动（IADL）残疾的能力，并提供不同基线运动表现水平下出现残疾的概率估计。
来自爱尔兰纵向老龄化研究前两波的数据，该研究评估≥50岁成年人老龄化的健康、经济和社会方面。
一个具有全国代表性的、基于人群的社区居住成年人样本。
≥65岁的参与者在健康评估期间完成了运动测试，在ADL/IADL方面无报告困难，且简易精神状态检查表得分≥24，2年后再次接受访谈（n = 1664）。
不适用。
参与者在基线时完成TUG和UGS，并在随访时指出在一些基本ADL和IADL方面存在困难。
受试者工作特征分析表明，TUG和UGS是预测ADL和IADL残疾的可接受工具（曲线下面积[AUC]=0.65 - 0.75），两者之间无显著差异（P>0.05）。两者都是高级功能任务（如准备热餐、服药和理财）困难的优秀预测指标（AUC>0.80）。在一系列表现水平上获得了预测概率。
TUG和UGS在预测基本ADL和IADL出现残疾方面具有相似的预测能力。预测概率可用于识别那些风险最高且需要特殊服务的人。由于改善身体功能可以预防或延迟ADL/IADL中的依赖，TUG和UGS还可以在运动干预期间提供表现目标和反馈。
