Abstract
BACKGROUND: Dry mouth, masticatory discomfort, and swallowing in older individuals are important factors affecting overall health. To improve their quality of life, efforts are required to improve their oral function. Therefore, this study implemented a training program evaluating oral function to confirm improvements in swallowing. METHODS: The study was conducted for approximately 4 months, from Jul to Oct 2023. Participants aged 65 yr or older were selected from welfare facilities in the metropolitan region, with 24 participants in both the intervention and control groups. RESULTS: As a result of a study conducted on oral function training program, the intervention group exhibited significant improvements in the simulated swallowing flow rate (P <0.05), bite force (P <0.001), and tongue pressure (P <0.001). CONCLUSION: The oral function training program effectively improved simulated swallowing flow rate, bite force, and tongue pressure. Consequently, there is an opportunity to implement oral function training programs at accessible welfare centers for older individuals in the community.
