To determine the reliability of the minimum sit-to-stand height test, its responsiveness and its relationship to leg muscle strength among rehabilitation unit inpatients and outpatients.
Reliability study using two measurers and two test occasions. Secondary analysis of data from two clinical trials.
Inpatient and outpatient rehabilitation services in three public hospitals.
Eighteen hospital patients and five others participated in the reliability study. Seventy-two rehabilitation unit inpatients and 80 outpatients participated in the clinical trials.
The minimum sit-to-stand height test was assessed using a standard procedure. For the reliability study, a second tester repeated the minimum sit-to-stand height test on the same day. In the inpatient clinical trial the measures were repeated two weeks later. In the outpatient trial the measures were repeated five weeks later. Knee extensor muscle strength was assessed in the clinical trials using a hand-held dynamometer.
The reliability for the minimum sit-to-stand height test was excellent (intraclass correlation coefficient (ICC) 0.91, 95% confidence interval (CI) 0.81-0.96). The standard error of measurement was 34 mm. Responsiveness was moderate in the inpatient trial (effect size: 0.53) but small in the outpatient trial (effect size: 0.16). A small proportion (8-17%) of variability in minimum sit-to-stand height test was explained by knee extensor muscle strength.
The minimum sit-to-stand height test has excellent reliability and moderate responsiveness in an inpatient rehabilitation setting. Responsiveness in an outpatient rehabilitation setting requires further investigation. Performance is influenced by factors other than knee extensor muscle strength.
确定最小坐站高测试的可靠性、其反应性以及与康复单元住院患者和门诊患者腿部肌肉力量的关系。
使用两名测量员和两个测试时间点进行可靠性研究。对两项临床试验数据的二次分析。
三家公立医院的住院和门诊康复服务。
18 名住院患者和另外 5 名参与者参加了可靠性研究。72 名康复单元住院患者和 80 名门诊患者参加了临床试验。
使用标准程序评估最小坐站高测试。对于可靠性研究,第二名测试员在同一天重复进行最小坐站高测试。在住院临床试验中,两周后再次测量。在门诊试验中,五周后再次测量。在临床试验中,使用手持式测力计评估膝关节伸肌力量。
最小坐站高测试的可靠性非常好(组内相关系数(ICC)0.91,95%置信区间(CI)0.81-0.96)。测量的标准误差为 34 毫米。住院试验中的反应性中等(效应量:0.53),但门诊试验中的反应性较小(效应量:0.16)。最小坐站高测试的变异有 8-17%可以用膝关节伸肌力量来解释。
最小坐站高测试在住院康复环境中具有非常好的可靠性和中等的反应性。在门诊康复环境中的反应性需要进一步研究。表现受膝关节伸肌力量以外的因素影响。
