| Outline of Final Research Achievements |
Stroke is a typical disease that causes gait disability due to hemiplegia and sensory disorder. Using ankle-foot orthosis (AFO) is an effective treatment for post stroke gait disability. Although adjustment of AFO stiffness magnitude improve abnormal kinematics, there are no clear criteria for selecting appropriate AFO stiffness in individuals with stroke. We propose the AFO stiffness selection support system using only single RGB camera and 2D knee kinematics analysis. Healthy adults and individuals with stroke were recorded various gait conditions by a RGB camera. The system may have a great potential to support appropriate AFO stiffness selection for individuals with stroke as a simple and easy to use measurement system.

| Academic Significance and Societal Importance of the Research Achievements |
脳卒中を発症した者は歩行能力が大きく低下し，歩行困難となるものも多い．下肢装具は歩行能力の改善に有効ではあるものの，アシスト量が装具の種類によって異なるため，個人にあわせた設計を行うことが難しい．
本研究により簡易かつ正確に，使用する装具のアシスト量を提案することが可能となることで，医療従事者の負担軽減や効率的な医療のための治療計画支援が期待できる．その他にも新たな治療用装具やアシストデバイスの評価や開発につながる可能性もあり，その学術的意義や社会的意義は高いと考えられる．
