摘要
目的:探讨基于压电式测力平台检测压力中心算法的精确性,为其推广应用研究提供客观依据。方法:以压力中心算法推导为基础,应用DLUT6040-1压电式测力平台分别从静态与动态模式进行2次测试,每次测试时,分别有2位操作者重复测试2次,并对静态与动态测试结果进行分析。结果:2次测试结果各指标高度相关,动态验证与静态验证相比,COP输出力值的计算误差基本没有显著差异。结论:压电式测力平台用于评定人体压力中心具有较高的精确性,适用于各群体人体步态研究及矫形康复行走机能评定,可进一步推广使用。
Objective To study the reliability and accuracy of center of pressure measured by piezoelectric force plate, and to provide a useful reference for further application. Methods Piezoelectric force plate was utilized to measure the center of pressure twice a week. All the testing was performed by two operators, respectively, with dynamic and static measurement at each assessment in the study. Results There were moderate to high correlations in all the parameters of COP between the two assessments. Conclusion The COP measured by piezoelectric force plate has high reliability and accuracy. It can be successfully used in evaluation of gait and rehabilitation.[Chinese Medical Equipment Journal,2010,31 （4）：21-23]
