| 摘要
目的：探讨6—7岁儿童扁平足的发生概率，并进一步调查扁平足的生物力学特征。
方法：利用MIMICS软件测量210足在负重位时足弓高度和足跟外翻度数，并通过Footscan数据测量比较正常足和扁平足的足底压力区域和接触面积的不同，进行统计学分析。
结果：此年龄段内扁平足的生物力学特征即为足弓高度低于22.93mm，足弓塌陷发生率为31.43%；足跟外翻角度大于7.66°，发生概率为87.62%。两者同时发生的概率约为27.61%。与正常足足底压力和接触面积相比，扁平足足底压力主要集中在前足的第二跖区、第三跖区和足跟内侧区域，中足接触面积增加41.9%。
结论：6—7岁儿童中扁平足约占三分之一，本研究为儿童足部健康调查及鞋类设计提供了一些参数。 |

| Abstract
Objective：Exploring the occurrence and biomechanical behavior of 6—7 years children flatfoot.
Method：The arch height and heel valgus degree of 210 feet during weight bearing were taken with SHANGHE and MIMICS. And then, the plantar pressure and contact area were measured with Footscan.
Result：The biomechanical characters of flatfoot in this age group was that the incidence of arch collapse lower than 22.93mm is 31.43%；Probability of heel valgus angle greater than 7.66° is 87.62%. The incidence of both was about 27.61%. Compared with the normal foot， the plantar pressure of flatfoot mainly concentrated on regions of the second metatarsal， the third metatarsal and the medial heel； the contact area of the midfoot increased by 41.9%.
Conclusion：About a third of 6—7y children is flatfoot. This will provide the refference data for the children's foot health and shoe design. |
