Abstract

Lingual strength and swallowing pressures have been studied extensively in dysphagia rehabilitation literature; however, little research has considered how lingual pressure generation may relate to parameters of swallowing speed and endurance. Additionally, little is known about the ability of the tongue to generate pressure to a given target, known as lingual control. This project collected measures of lingual pressure and measures of swallowing speed and endurance in 10 healthy, young adults. Specifically it explored if lingual strength or control of the anterior and posterior tongue correlate with endurance or speed during saliva and water swallowing tasks. Significant relations among lingual pressures and water swallowing measures were found. Maximal isometric anterior lingual pressures (i.e., tongue strength) were positively correlated with swallowing speed and negatively correlated with endurance during water swallows; however, greater accuracy of lingual control by the anterior tongue to reach small pressure targets correlated with both greater speed and endurance during water swallowing. Results suggest that in healthy adults, both anterior tongue strength and control may contribute to swallowing performance. Therefore, both lingual strength and skill training have potential to advance swallowing rehabilitation, specifically when targeting factors of swallowing speed and endurance.
