Outline of Research at the Start

本研究では,高齢者の身体バランス異常による転倒を未然に検出し,重心位置を正常へ誘導することにより転倒を未然に防ぐことが可能な装着型歩行支援靴の開発を行う.近年,高齢化がますます深刻化する我が国において,高齢者の転倒は医療及びリハビリテーション分野において喫緊の課題とされている.本研究では,体重心位置と支持基底面の関係性に着目し,全身バランスが崩れた際に体重心位置を水平面において支持基底面内に誘導可能な靴底機構を有する装着型歩行支援靴の開発を行う.本研究により,高齢者が転倒を怖がらずに自身の脚で歩行を続けることが可能となり,高齢者のQOL(生活の質)向上が見込まれ,健康寿命の延伸が期待される.

Outline of Final Research Achievements

In this study, we developed a walking support shoe that can prevent falls due to abnormalities in the balance of elderly people by detecting falls before they occur and guiding the user's center of gravity to a normal position. In particular, we aimed to develop a walking support shoe that can prevent falls by maximizing human functions, rather than a power-assist device with a high-output driving system. Specifically, we focused on the relationship between the center of body weight and the base support surface, and developed a walking support shoe with a sole mechanism that can guide the center of body weight to the base support surface in the horizontal plane when the balance of the whole body is off.

Academic Significance and Societal Importance of the Research Achievements

現在3千万人以上とされる下肢機能障害者や,若年層を含む歩行中に痛みを抱える人々が機器の装着に対する不安感や違和感を取り除くことが可能となり,また正常な筋骨格アライメントへ誘導することにより,歩行中の痛みの低減,さらには人間らしい歩容の実現が期待される.この人間らしい歩容の実現は,下肢機能障害者の精神的ストレスの減少につながり,下肢機能障害者と健常者の差を縮めることを可能とし将来的なQOL向上にもつながりうる.また軟部組織への影響を考慮した歩行支援靴の実現は,医学的見地に基づいた筋力リハビリを可能にすることが明白である.
