Remote Assessment of Gait Deterioration Due to Memory Impairment in Elderly Adults Using Micro-Doppler Radar

Abstract

This paper presents a technique to remotely assess gait deterioration due to memory impairment using micro-Doppler radar for elderly adults, aged 75 years and over. We introduce a micro-Doppler radar system to extract gait velocity parameters and investigate the relationship between the extracted parameters and the scores of a memory test using a scenery picture. The experimental results show significant differences between the low-and high-memory ability groups in the extracted parameters, and verifies the effectiveness of not only the gait speed but also the leg speed parameters for the screening of memory impairment.
