Abstract

Purpose: In the present study, the authors investigated lingual propulsive pressures generated in the normal swallow by the anterior and posterior lingual segments for various consistencies and maximum isometric tasks. Method: Lingual pressures for saliva, thin, and honey-thick liquid boluses were measured via the Iowa Oral Performance Instrument (IOPI Medical, Carnation, WA) at both anteromedian and posteromedian lingual segments of 62 healthy participants, ages 18-34 years (30 men, 32 women).Results: A repeated-measures analysis of variance revealed that all lingual swallowing pressures were significantly greater at the anteromedian segment than at the posteromedian segment. Gender was not a significant factor; however, women exhibited greater swallowing pressures across all conditions. Lingual pressures increased as bolus viscosity increased. No significant interactions existed. Analysis of a subset of 30 participants revealed that men exhibited greater maximal isometric pressure at the anteromedian segment than women, with no significant gender difference at the posteromedian segment. A significantly higher percentage of maximum isometric tongue pressure was exerted by the posteromedian tongue than by the anteromedian tongue. Conclusion: Findings suggest that greater amplitudes of lingual pressures are generated during normal swallowing at the anteromedian lingual segment; however, a greater percentage of maximum isometric tongue pressure was exerted by the posteromedian lingual segment, suggesting increased effort by the posterior tongue during bolus propulsion.
