The aim of this pilot study was to investigate the possibility to find a correlation between the output from a portable pedobarography system and the walking intensity expressed as walking speed. The system uses shoe insoles with force sensing resistors and wireless transmission of the data via Bluetooth. The force-time integral, at the toe-off phase of the step, for the force sensors in the forward part of the right foot was used to measure impulse data for 10 subjects performing walks in three different walking speeds. This data was then corrected by multiplication with the step frequency. This pilot study indicates that the portable pedobarography system output shows a linear relationship with the walking intensity expressed as walking speed on an individual level.
这项初步研究的目的是调查能否找到便携式足底压力测量系统的输出与以步行速度表示的步行强度之间的相关性。该系统使用带有力敏电阻的鞋垫，并通过蓝牙进行数据无线传输。在10名受试者以三种不同步行速度行走时，利用右脚前部力传感器在步幅蹬离阶段的力-时间积分来测量冲量数据。然后，通过乘以步频对该数据进行校正。这项初步研究表明，便携式足底压力测量系统的输出在个体水平上与以步行速度表示的步行强度呈线性关系。
