Abstract

Objective

Ely's, Ober's, and modified Thomas' tests are widely used. Stretching the front thigh involves two layers of tissue: the rectus femoris and its overlying fascia lata (FL). However, to our knowledge, no biomechanical study has analyzed these tests. Therefore, this study tries to determine the structures affected during the stretching of the front thigh.

Methods

An observational study of the front thigh was conducted. The directions and intensities of the reaction forces were recorded. The patellar travel was used to determine the average coordinates of the stretched structures at hip level in the horizontal plane. The participants indicated the stretched area. The stretch of a patient with a complete tear of his left rectus femoris was recorded.

Results

The reaction force of the thigh was oriented at 33° (standard deviation [SD]: 6°) sideways and its intensity was 60 N m (SD: 19 N m). The centroid coordinates of all stretched structures were stable. The registered average external rotational torque of 6 N m (SD: 3.7 N m) could only be mediated by the FL. The stretched area indicated by the participants could be anywhere on the FL. The tolerated reaction force increased in the same way on the disinserted rectus femoris thigh and on the uninjured thigh.

Conclusion

Ober's, Modified Thomas', and Ely's tests are three potential means of assessing FL extensibility. A lateral patellar tilt may be triggered by the FL's reaction force to stretching. Stretch tolerance seems to be limited by the FL, the fascia profundis of the thigh.

股四头肌拉伸涉及哪些机械和本体感觉结构？为什么髌骨行程很重要？

客观易利氏试验、奥伯氏试验和改良托马斯试验被广泛使用。大腿前侧的拉伸涉及到两层组织：股直肌及其覆盖的筋膜（FL）。然而，据我们所知，还没有生物力学研究对这些测试进行过分析。因此，本研究试图确定大腿前侧拉伸过程中受影响的结构。记录了反作用力的方向和强度。利用髌骨行程确定被拉伸结构在臀部水平面的平均坐标。参与者标出拉伸区域。结果大腿的反作用力方向为 33°（标准偏差 [SD]：6°），反作用力强度为 60 牛米（标准偏差：19 牛米）。所有拉伸结构的中心坐标都很稳定。记录的平均外部旋转力矩为 6 牛米（标准差：3.7 牛米），只能由 FL 介导。参与者所指的拉伸区域可能在 FL 的任何位置。在股直肌脱位的大腿和未受伤的大腿上，可承受的反作用力以相同的方式增加。FL对拉伸的反作用力可能会引发髌骨外侧倾斜。拉伸耐受性似乎受到 FL 和大腿深筋膜的限制。
