[Purpose] The purpose of this study was to determine the reliability of the active knee extension (AKE) test among healthy adults. [Subjects] Fourteen healthy participants (10 men and 4 women) volunteered and gave informed consent. [Methods] Two raters conducted AKE tests independently with the aid of a simple and inexpensive stabilizing apparatus. Each knee was measured twice, and the AKE test was repeated one week later. [Results] The interrater reliability intraclass correlation coefficients (ICC2,1) were 0.87 for the dominant knee and 0.81 for the nondominant knee. In addition, the intrarater (test-retest) reliability ICC3,1 values range between 0.78-0.97 and 0.75-0.84 for raters 1 and 2 respectively. The percentages of agreement within 10° for AKE measurements were 93% for the dominant knee and 79% for the nondominant knee. [Conclusion] The finding suggests the current AKE test showed excellent interrater and intrarater reliability for assessing hamstring flexibility in healthy adults.
[目的] 本研究旨在确定主动伸膝（AKE）测试在健康成年人中的可靠性。[受试者] 14名健康参与者（10名男性和4名女性）自愿参与并签署了知情同意书。[方法] 两名评估者借助一种简单且廉价的稳定装置独立进行AKE测试。每个膝关节测量两次，一周后重复进行AKE测试。[结果] 评估者间可靠性组内相关系数（ICC2,1），优势膝关节为0.87，非优势膝关节为0.81。此外，评估者1和评估者2的评估者内（重测）可靠性ICC3,1值分别在0.78 - 0.97和0.75 - 0.84之间。AKE测量在10°范围内的一致性百分比，优势膝关节为93%，非优势膝关节为79%。[结论] 研究结果表明，当前的AKE测试在评估健康成年人腘绳肌柔韧性方面显示出出色的评估者间和评估者内可靠性。
