Verification of Fall Experiences Identification Method of Healthy Elderly People Using Gate Parameters during Dual Task Walk

Abstract

This study verifies an evaluation index of fall experience using dual-task walk and concept of working memory model. Two kinds of recall problem were given to 70 healthy elderly people during level ground walking. Eighteen subjects experienced fall within past one year. Stride length of every step is estimated using tiptoe mounted inertial sensor. Relation between Stride length and difficulty of induced question is investigated. The experimental results show that an attention coefficient for walk of fall experienced subjects were significantly smaller than that of fall unexperienced one.
