New method to analyze the load propagation on the plantar foot surface during a walk/run using the smart sock system

Abstract

A new version of DAid® Pressure Sock System (DPSS) for gate monitoring and new method of data processing and analysis are presented. Proposed DPSS has 6 sensing elements, electronic device with sampling rate up to 200 Hz and is able to monitor walking/running gates in outdoor conditions. According to a new method the process of plantar loading during the gate is considered similar to seismic wave propagation and sensors assumed as the reference points. As a result, harvested data after being processed, are represented in the form of loading wave plots (WPs). Obtained WPs show load propagation across the sensors during the stance/gate. Primary tests of developed system and method were made for different types of walk/run and correspondence of conclusions from WPs analysis and diagnoses made by sport medicine doctor during walk/run tests confirms system efficacy and validity of results.
