青年人快速行走足底压力变化的研究

目的研究足底各区域压力分布的变化及其规律，为案件现场足迹分析提供理论基础与科学依据，促进足迹标准化与定量化检验。方法利用Footscan足底压力步态分析系统，采集15名青年人快速行走和常速行走时足底压力的数据，运用SPSS软件对两种步速下足底主要承重区域压力的分布特点作相关性分析和比较研究。结果足底各区域压力分布相关性不大，反映出压力有不同程度的改变。结论现场足迹分析时，应结合具体案情及犯罪嫌疑人的活动情况，准确把握足迹特征的变化以获得理想的分析结果。

Research on change of foot pressure in young people during fast walking

Objective To provide theoretical and scientific basis for standardized and quantitative analysis of footprint. Methods 15 young people were selected to walk normally and fast on the Footscan plate and then their foot pressure data were collected, Pearson correlation analysis and t-test were conducted with SPSS. Results Pearson correlation was low for the main bearing regions under the foot to various change in foot pressure. Conclusion Details of cases and the activities of the suspects should be considered in footprint analysis.
