A Study on Detection of Biased Gait by Using Acceleration Signal

Abstract:

This study was performed in order to detect biased gait being occurred due to vestibular abnormality by using a data of acceleration being generated at foot during gait. Characteristics of acceleration being generated during gait was observed by comparing movement analysis data that was collected in a process of performing biased gait and general gait through induction of galvanic vestibular stimulation with acceleration data and biased direction and degree could be inferred through cumulative value of acceleration data by integrating it. As a result, it could be inferred that detecting gait bias after analyzing gait trajectory by using acceleration of left, right direction would be a feasible method. A significance of this study could be found in that a new possibility of utilizing acceleration was presented in an analysis of gait utilizing acceleration data. It is expected that the result of this study would be utilized for detecting abnormal gait that may be taken place by malfunction or damage of sensory receptor such as vestibular organ.
