The accuracy of video analysis of the passive straight-leg raise test (PSLR) and the validity of the sit-and-reach test (SR) were tested in 60 men and women. Computer software measured static hip-joint flexion accurately. High within-session reliability of the PSLR was demonstrated (R > .97). Test-retest (separate days) reliability for SR was high in men (R = .97) and women R = .98) moderate for PSLR in men (R = .79) and women (R = .89). SR validity (PSLR as criterion) was higher in women (Day 1, r = .69; Day 2, r = .81) than men (Day 1, r = .64; Day 2, r = .66). In conclusion, video analysis is accurate and feasible for assessing static joint angles, PSLR and SR tests are very reliable methods for assessing flexibility, and the SR validity for hamstring flexibility was found to be moderate in women and low in men.
视频分析被动直腿抬高测试（PSLR）和坐立伸展测试（SR）的准确性，以及坐立伸展测试的有效性，在 60 名男性和女性中进行了测试。计算机软件可以准确测量静态髋关节屈曲。PSLR 的组内测试具有很高的可靠性（R>.97）。男性的 SR 测试-再测试（间隔几天）可靠性较高（R=.97），女性的可靠性较高（R=.98）。男性的 PSLR 测试-再测试可靠性中等（R=.79），女性的可靠性中等（R=.89）。在女性中，SR 的有效性（PSLR 作为标准）较高（第 1 天，r=.69；第 2 天，r=.81），而在男性中则较低（第 1 天，r=.64；第 2 天，r=.66）。总之，视频分析是评估静态关节角度的准确且可行的方法，PSLR 和 SR 测试是评估柔韧性的非常可靠的方法，女性的坐立伸展测试有效性适中，而男性的有效性较低。
