Design of an Insole using Force Sensing Resistors for Gait Analysis and Validation using Zebris FDM System

Abstract

In this study, we present an insole with three Force Sensing Resistors (FSR) one each for toe, hallux and heel which provides quantitative gait analysis outside the confinement of traditional lab at a low cost. The aim of the study was to explore the validity and reliability of the insole in a healthy individual. Gait data were collected from a healthy individual at three different paces of walking. Validation of the data was performed with zebris FDM system. Through a series of analytical tests we tested the accuracy and validated the performance of FSR insole. With the future scope being, developing an algorithm for a smartphone app that acquires the acceleration signal from the insole for users to assess the abnormality of gait.
