OBJECTIVE
The timed 'Up & Go' test and '30second Chair-Stand' test are simple clinical outcome measures widely used to assess functional performance. The reliability of both tests in hospitalised stroke patients is unknown. The purpose was to investigate the relative and absolute reliability of both tests in patients admitted to an acute stroke unit.
METHODS
Sixty-two patients (men, n = 41) attended two test sessions separated by a one hours rest. Intraclass correlation coefficients (ICC2,1) were calculated to assess relative reliability. Absolute reliability was expressed as Standard Error of Measurement (with 95% certainty-SEM95) and Smallest Real Difference (SRD) and as percentage of their respective means if heteroscedasticity was observed in Bland Altman plots (SEM95% and SRD%).
RESULTS
ICC values for interrater reliability were 0.97 and 0.99 for the timed 'Up & Go' test and 0.88 and 0.94 for '30second Chair-Stand' test, respectively. ICC values for intrarater reliability were 0.95 and 0.96 for the timed 'Up & Go' test and 0.87 and 0.91 for '30second Chair-Stand' test, respectively. Heteroscedasticity was observed in the timed 'Up & Go' test. Interrater SEM95% ranged from 9.8% to 14.2% with corresponding SRD% of 13.9-20.1%. Intrarater SEM95% ranged from 15.8% to 18.7% with corresponding SRD% of 22.3-26.5%. For '30second Chair-Stand' test interrater SEM95 ranged between 1.5 and 1.9 repetitions with corresponding SRD of 2 and 3 and intrarater SEM95 ranged between 1.8 and 2.0 repetitions with corresponding SRD values of 3.
CONCLUSION
Excellent reliability was observed for the timed 'Up & Go' test and the '30second Chair-Stand' test in hospitalised stroke patients. The thresholds to detect a real change in performance were 18.7% for the timed 'Up & Go' test and 2.0 repetitions for the '30second Chair-Stand' in groups of patients and 26.5% and 3 repetitions in individual patients, respectively.
目的
定时“起立-行走”测试和“30秒坐立”测试是广泛用于评估功能表现的简单临床结局指标。这两项测试在住院卒中患者中的可靠性尚不清楚。本研究旨在调查这两项测试在急性卒中单元收治患者中的相对可靠性和绝对可靠性。
方法
62例患者（男性41例）参加了两次测试，中间休息1小时。计算组内相关系数（ICC2,1）以评估相对可靠性。绝对可靠性用测量标准误（95%置信区间-SEM95）和最小真实差异（SRD）表示，若在布兰德-奥特曼图中观察到异方差性，则用其各自均值的百分比表示（SEM95%和SRD%）。
结果
定时“起立-行走”测试的评分者间可靠性ICC值分别为0.97和0.99，“30秒坐立”测试的ICC值分别为0.88和0.94。定时“起立-行走”测试的评分者内可靠性ICC值分别为0.95和0.96，“30秒坐立”测试的ICC值分别为0.87和0.91。在定时“起立-行走”测试中观察到异方差性。评分者间SEM95%范围为9.8%至14.2%，相应的SRD%为13.9 - 20.1%。评分者内SEM95%范围为15.8%至18.7%，相应的SRD%为22.3 - 26.5%。对于“30秒坐立”测试，评分者间SEM95范围在1.5至1.9次重复之间，相应的SRD为2至3次，评分者内SEM95范围在1.8至2.0次重复之间，相应的SRD值为3次。
结论
在住院卒中患者中，定时“起立-行走”测试和“30秒坐立”测试具有出色的可靠性。在患者组中，定时“起立-行走”测试检测性能实际变化的阈值为18.7%，“30秒坐立”测试为2.0次重复；在个体患者中，分别为26.5%和3次重复。
