Outline of Final Research Achievements

In this study, we aimed to develop a visual feedback program that visualizes muscle tension and relaxation and a system that evaluates the effectiveness of relaxation methods by measuring the activity of autonomic nervous responses (sympathetic and parasympathetic nervous responses) to effectively provide stress management education. As a result, we have completed a program that provides visual feedback on the degree of muscle tension in the form of a graph using electromyogram signals. We also completed a program to measure autonomic nervous system activity using a simple, easy-to-wear photoplethysmography.

Academic Significance and Societal Importance of the Research Achievements

感覚-運動処理に問題をもつ発達性協調運動児・者を対象に、リラクセーション法（漸新的筋弛緩法）を導入するための、視覚的なフィードバックシステムは、その技法の習得を支援ができるだろう。また、リラクセーション法の習得とその効果を自律神経（特に副交感神経）の活動を指標とするシステムを準備することで、今後の二次障害の予防に向けたストレスマネジメント教育を客観的に進めることが可能となる。
