The importance of the plantar tensile systems of the foot are studied by the means of photoelasticity. In a plastic (VP 1527) model of the sagittal section of a foot skeleton the distribution of stressing under load has been visualized in photographs of the isochromes as seen in the polarized light. This examination has been carried out with and without tension in the long plantar tensile systems of the model. It has clearly been shown that by the influence of the tensile systems the resultant force for the forefoot runs approximately in the axis of the bony elements of the metatarsus. In absence of these plantar tensions on the contrary the metatarsal elements undergo considerable bending stresses.
通过光弹性方法研究了足部足底拉伸系统的重要性。在足部骨骼矢状面的塑料（VP 1527）模型中，在偏振光下拍摄的等色线照片中可以看到负载下应力的分布情况。该检查在模型的长足底拉伸系统有张力和无张力的情况下都进行了。结果清楚地表明，由于拉伸系统的影响，前足的合力大致沿跖骨骨元件的轴线方向。相反，在没有这些足底张力的情况下，跖骨元件会承受相当大的弯曲应力。
