| Outline of Final Research Achievements |
It contributed to establishing epidemiological surveys, establishment of diagnostic criteria, and criteria of severity evaluation in the course of accumulating voice function and clinical diagnosis in cases of spasmodic dysphonia whose etiology/pathology was not clear. In addition, it contributed to the doctor-led clinical trial in the case study, and the laryngeal musucle intramuscular injection treatment of botulinum toxin type A became the insurance coverage of spasmodic dysphonia. We were able to construct data that could lead the examined cases to brain imaging evaluation by functional MRI.

| Academic Significance and Societal Importance of the Research Achievements |
痙攣性発声障害症例の音声機能評価、喉頭所見などの評価を蓄積することで、病態・病因の解明に近づけた。また、「原因不明」「心理的要因」「精神的疾患」などと判断され、臨床的診断や治療が困難であった痙攣性発声障害が、診断基準に基づいて正しい診断、治療へとむすびつける一助になった。
