腿筋肌肉可以限制髋关节屈曲，特别是当膝盖伸展时。据推测，腿筋短或紧绷的个体在某些坐姿时骨盆会异常倾斜，腰椎前凸更平坦或逆转。研究对象是健康成年人。采用触趾试验测量髋关节屈曲范围。在站立、膝盖屈曲和膝盖部分伸直时分别测量腰椎曲度。发现髋屈曲范围有很大的个体差异。范围小的人在第二坐姿时脊柱弯曲的变化最明显。结论是，在设计工作场所时，应注意腿筋对腰椎的影响。
The hamstring muscles can restrict hip flexion, especially when the knees are extended. It was hypothesized that individuals with short or tight hamstrings would have abnormal tilting of the pelvis in some seated postures, with greater flattening or reversal of the lumbar lordosis. Healthy adults were studied. A toe-touch test was used to measure range of hip flexion. Lumbar spine curvature was measured in standing, in sitting with the knees flexed, and in sitting with knees partially extended. Large individual variations in range of hip flexion were found. Persons with a small range had the most pronounced change in spine curvature in the second seated posture. It is concluded that attention should be given to this effect of the hamstrings on the lumbar spine when workplaces are designed.
