足底圧力分布の標準分布に基づく健康状態評価手法の開発

Abstract

This paper proposes an evaluation method for autonomy walk by using sole pressure that measured mat type load distribution sensor. The sole pressure data is changed by posture and kicking force of walker. This study tries to find abnormal gait from footprint information. The footprints that maid from the sole pressure data is also reflected foot shape of walker. However, abnormal gait reduces area of footprint. For example, toe area is vanished from walker with floating toes. Our method makes template footprint from 256 subjects, and degree of normal gait is calculated from comparison results with obtained data and the template. In the experiment, we apply the method to the patient's data during rehabilitation and confirmed its effectiveness.
