Outline of Final Research Achievements

The purpose of the study was to develop a "Smile Utilization Reading Model" for the prevention of aspiration in the elderly. A crossover study design was used with 13 elderly residents in the community.
The results showed that both "Telling Old Tales" and " Reading Aloud " were associated with movements of facial muscles, including feeding and swallowing-related muscle groups, and with swallowing function. In addition, "Telling Old Tales" showed higher activity of the three facial expression muscles of the ingestion- and swallowing-related muscle groups than "Reading Aloud," and "Reading Aloud" was associated with activity of many ingestion- and swallowing-related muscle groups and swallowing function. In order to develop a " Smile Utilization Reading Model", it is necessary to examine the specific content of "Reading Alound" that significantly moves each facial muscle and improves the mood, and to verify the effectiveness of this model.

Academic Significance and Societal Importance of the Research Achievements

本研究は、「発話」と嚥下が関与する抹消効果器官の多くが互いに重複していることから、非日常となる訓練ではなく、高齢者の日常にある「発話」に着目して、誤嚥性肺炎を予防するケア方法を探索している。
今回は、『昔語り』と『朗読」の各発話の利点を活かし、ケア提供者に依存することなく継続的に援助ができ、摂食嚥下関連筋である表情筋の活動に結びつく感情に変化をもたらす高齢者の誤嚥予防のための『笑顔活用朗読モデル』の開発を行う。
