PURPOSE
To determine test-retest reliability and minimal detectable change of the Timed Up and Go (TUG) and Timed Up and Down Stairs (TUDS) for Down syndrome.
SUBJECTS
Twelve children with Down syndrome (DS) aged 3 to 17 years.
METHODS
Two sessions, 1 week apart, with 3 trials of the TUG and 2 trials of the TUDS. Test-retest reliability was estimated using intraclass correlation coefficients and the standard error of measurement. The minimal detectable changes (MDCs) for both tests were calculated.
RESULTS
The TUG and TUDS tests both had high test-retest reliability. The MDC was 1.26 seconds for the TUG and 12.52 seconds for the TUDS test.
CONCLUSIONS
Both tests were reliable in this population, but the MDC results suggest only the TUG is clinically useful.
目的
确定用于唐氏综合征的计时起立行走测试（TUG）和计时上下楼梯测试（TUDS）的重测信度及最小可检测变化。
受试者
12名年龄在3至17岁的唐氏综合征儿童。
方法
分两次测试，间隔1周，进行3次TUG测试和2次TUDS测试。使用组内相关系数和测量标准误差评估重测信度。计算两项测试的最小可检测变化（MDC）。
结果
TUG和TUDS测试均具有较高的重测信度。TUG测试的MDC为1.26秒，TUDS测试的MDC为12.52秒。
结论
两项测试在该人群中均具有可靠性，但MDC结果表明只有TUG在临床上有用。
