The purpose of this study was to determine whether stretching the hamstring muscles affects extensibility, as indicated by straight leg raising (SLR), lumbopelvic posture, and the relative amounts of lumbar and hip motion during forward bending.
Thirty-nine subjects without known musculoskeletal impairments of their spine or lower extremities and with tight hamstring muscles (ie, SLR of < or = 70 degrees) were randomly assigned to either a stretching group or a control group.
A three-dimensional digitizer was used to measure lumbar, pelvic, and hip positions while subjects were in a standing position and during partial and full forward bending.
Straight leg raising and hip motion during late and total forward bending were increased after stretching. No changes occurred in standing posture or lumbar motion during forward bending.
The results of this study suggest that there is no relationship between hamstring muscle length and lumbopelvic posture. There was some indication, however, that stretching the hamstring muscles may affect motion during forward bending.
本研究旨在确定拉伸腘绳肌是否会影响直腿抬高（SLR）、腰骶骨盆姿势以及前屈过程中腰椎和髋关节的相对运动幅度所显示的伸展性。
39名无已知脊柱或下肢肌肉骨骼损伤且腘绳肌紧张（即直腿抬高≤70度）的受试者被随机分为拉伸组或对照组。
使用三维数字化仪测量受试者站立位、部分前屈和完全前屈时的腰椎、骨盆和髋关节位置。
拉伸后，后期和完全前屈时的直腿抬高和髋关节运动幅度增加。前屈时的站立姿势或腰椎运动无变化。
本研究结果表明，腘绳肌长度与腰骶骨盆姿势之间没有关系。然而，有一些迹象表明，拉伸腘绳肌可能会影响前屈过程中的运动。
