| Outline of Final Research Achievements |
Spasmodic dysphonia is considered to be dystonia confined to the larynx, but it is difficult to distinguish it from similar diseases, and a standard evaluation method of severity and treatment effect has not been established. In this research project, we developed an evaluation algorithm based on auditory impression evaluation and acoustic analysis using the newly developed Visual Analog Scale. As a result of calculating sensitivity and specificity, it was shown that this evaluation algorithm is useful as an evaluation method that complements excluded diagnosis and definitive diagnosis.

| Academic Significance and Societal Importance of the Research Achievements |
話しことばの要素のうちで声帯を音源とする「こえ」の異常は、近年「発声障害」として社会的に注目され病院を訪れる患者数が爆発的に増加している。なかでも喉頭の局所性ジストニアとされる痙攣性発声障害は類似疾患との鑑別が専門家の間でも難しい。本研究課題は、聴覚印象評価と音響分析を組み合わせた痙攣性発声障害における評価アルゴリズムを開発し、本評価アルゴリズムが除外診断および確定診断を補う評価法として有用であることを示した。
