Abstract
Aim: This study investigated the effect of tongue strengthening exercise (TSE) on oropharyngeal muscle associated with swallowing of elder people living in nursing home.
Methods: In this study, 40 elderly adults living in the community were recruited and assigned to two groups. The experimental group received a TSE with a resistance level of 70% of 1-repetition maximum. Exercise was divided into isometric and isotonic exercises. The control group, on the other hand, did not receive any exercise. We measured the muscle strength and thickness of tongue and suprahyoid muscles using an Iowa oral performance instrument and ultrasonography.
Results: The experimental group showed a statistically significant increase in tongue muscle strength and thickness in the oral phase than in the control group (p = 0.001 and < 0.001). In the pharyngeal phase, the experimental group showed a significant increase in suprahyoid muscles (mylohyoid and digastric muscles) than the control group (p = 0.045 and 0.019).
Conclusion: This study suggests that TSE is an effective exercise for increasing the strength and thickness of the oropharyngeal muscle of the elderly and is recommended for the elderly who are vulnerable to swallowing
