四川地区3～11岁儿童足底压力分布的调查和研究

Survey and Study on Foot Loading Patterns of 3-11 Year-old Children in Sichuan Area

使用Footscanl米板压力测试系统，采集分析895位四川地区3～11岁儿童的足底压力参数，进而分析比较足底压力随年龄增长的变化趋势。结果表明，随着年龄的增长，腰窝区域的峰值压力、相对作用面积和相对冲量降低；除腰窝区域，其他四个区域的峰值压力和相对冲量，随年龄增长而逐渐增大。

The Footscan pressure measurement system was used in a protocol involving a dynamic test of 895 3-11 year-old children from Sichuan area, in order to explore age-related differences in toot pressure patterns. The result shows that, with the growth of the age, the mid foot recorded a lower PP, CArel and PTrel value; except the mid foot, PP and PTIrel were increasing gradually under other plantar regions.
