Outline of Final Research Achievements |
Our study hypothesized that tongue function influences the hardness of the submental superficial layer. We examined 28 healthy adults, using a Myoton PRO to measure the submental layer's properties and their correlation with tongue pressure. Measurements were taken at rest and during water retention, revealing significant differences in the submental layer's hardness between the two states. Higher frequency and stiffness, along with lower decrement, relaxation, and creep, were noted during water retention. The study indicates that tongue movements affect the mechanical properties of the submental superficial layer, offering insights into non-invasive assessment methods for swallowing function and potential early detection of dysphagia in the elderly. Our findings highlight the complex interplay between tongue function and swallowing mechanics, contributing to better understanding and management of swallowing disorders.

Academic Significance and Societal Importance of the Research Achievements |
現在使われている舌圧測定装置は、利用者が指示に従えなかったり口を開けるのが難しい場合には正確な測定ができないことがあります。そこで、この研究では筋硬度計を用いる方法を開発しました。これにより、測定が困難な人でも舌の運動をしっかり評価できるようになりました。また、この装置は持ち運びやすく、口腔内に挿入する必要がないため、清潔で簡単に舌の機能を客観的に測定できる点も大きな利点です。
