Hamstring tightness is a common condition typically assessed via the active knee extension (AKE), passive straight leg raise (PSLR), V-sit and reach (VSR), and finger-floor-distance (FFD).
The purpose of this study was to investigate the relationships between four common clinical tests of apparent hamstring tightness. A secondary purpose was to compare the differences in correlations between sub-groups based on positive test findings.
Descriptive, correlational laboratory design.
Recreationally active individuals (N = 81; 23.7 ± 5.9 years) performed the AKE, PSLR, VSR, and FFD in a randomized order, and subsequent correlational analyses were conducted.
Strong correlations were identified between the VSR and FFD (r = -.798, r = .637, p < .001); moderate correlations were demonstrated between the PSLR and FFD (r = -.565, r = .319, p < .001) and PSLR and VSR (r = .536, r = .287, p < .001). Low correlations were found between the PSLR and AKE (r = -.284, r = .081, p = 0.01), AKE and VSR (r = -.297, r = .088, p = .007), and AKE and FFD (r = .263, r = .069, p = .018). If one assessment was identified in a subject as dysfunctional, all relationships were affected, regardless of which assessment was dysfunctional.
The AKE, one of the most common measures for apparent hamstring tightness, has low correlations with the other assessments. Based on the findings of this study, it is possible that not all assessments of AHT are measuring the same phenomena, with each involving different factors of perceived hamstring length.
Level 2b.
腘绳肌紧张是一种常见情况，通常通过主动膝关节伸展（AKE）、被动直腿抬高（PSLR）、V型坐姿体前屈（VSR）和手指触地距离（FFD）来评估。
本研究的目的是调查四种常见的明显腘绳肌紧张临床测试之间的关系。次要目的是比较基于阳性测试结果的亚组之间相关性的差异。
描述性、相关性实验室设计。
从事休闲运动的个体（N = 81；23.7±5.9岁）以随机顺序进行AKE、PSLR、VSR和FFD测试，并进行后续的相关性分析。
VSR和FFD之间存在强相关性（r = -0.798，r = 0.637，p < 0.001）；PSLR和FFD之间以及PSLR和VSR之间存在中度相关性（r = -0.565，r = 0.319，p < 0.001；r = 0.536，r = 0.287，p < 0.001）。PSLR和AKE之间、AKE和VSR之间以及AKE和FFD之间存在低相关性（r = -0.284，r = 0.081，p = 0.01；r = -0.297，r = 0.088，p = 0.007；r = 0.263，r = 0.069，p = 0.018）。如果在一名受试者中确定一项评估功能异常，则所有关系都会受到影响，无论哪项评估功能异常。
AKE是评估明显腘绳肌紧张最常用的方法之一，与其他评估的相关性较低。基于本研究的结果，有可能并非所有的AHT评估都在测量相同的现象，每项评估涉及不同的腘绳肌长度感知因素。
