Hamstring muscle length may be associated with specific pelvic and trunk postures, but the influence of hamstring length on trunk postures is not well documented. The purposes of this study were to examine the influence of hamstring length on 1) the pelvic angle, lumbar angle, and thoracic angle in standing; and 2) the flexion ranges of motion of the pelvic angle, lumbar angle, and thoracic angle during the toe-touch test. Surface platform pointers over bony landmarks and photography were used to examine the pelvic and trunk angles and ranges of motion of 10 men with short hamstrings, 10 men with medium hamstrings, and 10 men with long hamstrings while standing and after assuming the toe-touch position. Separate one-way analyses of variance detected no significant differences among groups for the three angles in standing. Significant differences were detected among groups for the three angles in the toe-touch position and the flexion ranges of motion during the toe-touch test (p < 0.05). Short hamstrings were associated with decreased flexion range of motion of the pelvic angle and lumbar angle and increased flexion range of motion of the thoracic angle. Therapeutic interventions should be considered in light of the influences of hamstring length on the flexion range of motion of the pelvic angle, lumbar angle, and thoracic. angle.
腘绳肌长度可能与特定的骨盆和躯干姿势有关，但腘绳肌长度对躯干姿势的影响尚无充分记录。本研究的目的是检验腘绳肌长度对以下两方面的影响：1）站立时的骨盆角度、腰椎角度和胸椎角度；2）在触碰脚趾测试中骨盆角度、腰椎角度和胸椎角度的屈伸运动范围。使用骨性标志上的表面平台指针和摄影技术，对10名腘绳肌短的男性、10名腘绳肌中等长度的男性和10名腘绳肌长的男性在站立时以及采取触碰脚趾姿势后，检查其骨盆和躯干角度及运动范围。独立的单因素方差分析未发现三组在站立时这三个角度存在显著差异。在触碰脚趾姿势下这三个角度以及在触碰脚趾测试中的屈伸运动范围在三组之间检测到显著差异（p < 0.05）。腘绳肌短与骨盆角度和腰椎角度的屈伸运动范围减小以及胸椎角度的屈伸运动范围增加有关。应根据腘绳肌长度对骨盆角度、腰椎角度和胸椎角度屈伸运动范围的影响来考虑治疗干预措施。
