背景：足弓结构与损伤之间的相关性可能与足部结构影响足部功能的事实有关。足部结构通常由足弓高度定义，尽管足弓灵活性对于形成更完整的描述可能同样重要。我们提出了一个足弓柔韧性分类系统，类似于足弓高度分类，然后使用分类系统来检查足弓柔韧性和足弓height.Methods之间的关系：足弓高度指数计算在1,124名即将入学的军校学员，其中1,056人有可用的数据。通过测量坐着和站立时的足弓高度，也可以计算足弓柔韧性的测量值。这些值用于创建五个足弓柔韧性类别：非常僵硬、僵硬、中性、柔韧和非常柔韧。结果：拟合优度检验显示，每种牙弓高度类别中每种牙弓柔性类型的数量不成比例（P < .01）。高弓足比例最大，非常僵硬，比例最小，非常灵活。相反，比例最大的平坦脚是非常灵活的，最小的比例是非常stiff.Conclusions：这项研究的结果支持共同的信念，cavus脚往往是非常僵硬和平坦脚往往是非常灵活的。
Background: The correlation between arch structure and injury may be related to the fact that foot structure influences foot function. Foot structure is often defined by arch height, although arch flexibility may be just as important to form a more complete description. We propose an arch flexibility classification system, analogous to arch height classification, and then use the classification system to examine the relationship between arch flexibility and arch height.Methods: Arch height index was calculated in 1,124 incoming military cadets, of whom 1,056 had usable data. By measuring arch height during both sitting and standing, a measurement of arch flexibility could also be calculated. These values were used to create five arch flexibility categories: very stiff, stiff, neutral, flexible, and very flexible. The distribution of arch flexibility types among arch height categories was statistically compared.Results: The goodness of fit test showed a disproportionate number of each arch flexibility type in each of the arch height categories (P < .01). The largest proportion of cavus feet was very stiff and the smallest proportion was very flexible. Conversely, the largest proportion of planus feet was very flexible and the smallest proportion was very stiff.Conclusions: The results of this research support the common belief that cavus feet tend to be very stiff and planus feet tend to be very flexible.
