To evaluate the construct validity and the responsiveness of 3 measures of physical performance measures as outcome measures for frail older persons.
Pre-post design with measures at admission and discharge.
Three inpatient geriatric rehabilitation programs.
Fifty-two subjects (35 women, 17 men; age, 80+/-8y).
Not applicable.
Physical performance measures were Timed Up & Go (TUG) test, two-minute walk test (2MWT), and functional reach. Functional status was measured with the FIM instrument and the Modified Barthel Index.
The TUG and 2MWT scores differed significantly in groups of patients using different ambulatory aids (P=.006), whereas no such difference was observed for the functional reach (P=.40). The correlations between the TUG test and FIM and between the 2MWT and FIM were -.59 and .59 (P<.001), respectively, at admission, and -.42 and .47 (P< or =.04), respectively, at admission and discharge. The correlations between functional reach and the FIM were not significant (P> or =.09). Standardized response means were 1.1 for the TUG, 0.7 for the 2MWT, and 0.5 for functional reach.
The TUG test and 2MWT are valid and responsive outcome measures in older persons participating in geriatric rehabilitation. Functional reach was a moderately responsive outcome measure but did not consistently reflect ambulatory or functional status.
评估3种身体性能测量指标作为体弱老年人结局指标的结构效度和反应性。
采用入院和出院时测量的前后设计。
三个住院老年康复项目。
52名受试者（35名女性，17名男性；年龄，80±8岁）。
不适用。
身体性能测量指标为计时起立行走（TUG）测试、两分钟步行测试（2MWT）和功能性伸展。功能状态用FIM工具和改良巴氏指数进行测量。
在使用不同助行器的患者组中，TUG和2MWT评分有显著差异（P = .006），而功能性伸展未观察到此类差异（P = .40）。入院时，TUG测试与FIM之间以及2MWT与FIM之间的相关性分别为 -0.59和0.59（P < .001），入院和出院时分别为 -0.42和0.47（P ≤ .04）。功能性伸展与FIM之间的相关性不显著（P ≥ .09）。TUG的标准化反应均值为1.1，2MWT为0.7，功能性伸展为0.5。
TUG测试和2MWT是参与老年康复的老年人有效的结局指标且具有反应性。功能性伸展是一个反应性中等的结局指标，但不能始终反映步行或功能状态。
