Gait Evaluation Method Based on Sole Pressure by Using Sock Type Wearable Sensor

Abstract

Evaluating our gait is extremely useful for estimating our health condition and physical abilities. Traditionally, gait has been evaluated mainly by visual inspection by experts or by camera images using a motion capture system. In this study, we focus on changes in sole pressure distribution during walking and propose a gait analysis method using data measured by a sock-type wearable sensor. This method is based on fuzzy inference and is evaluated by comparing the results with standard values measured by a fixed mat-type sensor. We evaluated the usefulness of this method by applying it to healthy male subjects.
