組立て椅子が身体位置認識および身体能力認識に与える影響─ハビリテーションチェアのデザインと事例検討─

The effect of a knockdown chair on the awareness of a body's position and physical strength: A case study on the design of a rehabilitation chair

要旨：本報告の目的は，組立て椅子をデザインし，在宅障害者の身体位置認識および身体能力認識に与える影響を検討することである．以下2つの手続きで構成した．手順1：予備調査からハビリテーションチェアという組立て椅子をデザインし，プロトタイプを制作した．手順2：脳梗塞後左片麻痺1症例に対し，ハビリテーションチェアが組立て可能かについてと，身体位置認識および身体能力認識に対する影響について，事例検討を行った．その結果，組立てには介助を要し，パーツや工程，動機づけを再考する必要性があった．身体位置認識，身体能力認識に対しては影響を与える可能性が示唆された．今後は椅子を改善し，妥当性の検討を行っていく予定である．

　The purpose of this study was to design a knockdown chair, and examine influence of the chair on a person with left hemiplegia due to cerebral arterial disease. A two-round study was conducted: (1) the construction of a prototype based on physical research, and (2) the verification that the subject could use the prototype to assist QOL. The process of building the chair revealed difficulties due to the difficulty of maintaining awareness of both the body's strength and its position. Thus, it is necessary to reconsider the parts of the chair, the construction process, and the motivation of the user. Recognition of the body's position and physical strength may have an effect on the success of the design. The design of the chair will be improved and its appropriateness reconfirmed.
