Purpose: To examine the speed of hyolaryngeal excursion in different age and gender groups during normal swallowing. Methods: Temporal and biomechanical measurements of hyolaryngeal excursion were calculated using videofluoroscopic swallowing examinations (VFSEs) of 37 healthy individuals. Statistical comparisons were made by two-way repeated analysis of variance (ANOVA) with between subject variables being age and gender, and within subject variable being bolus volume (5 mL and 10 mL thin liquids). Significance level was set as p<0.025. Results: The speed of hyoid excursion in older populations was significantly slower than in younger ones. There was no gender or bolus volume difference or interaction in the speed of hyoid excursion. Conclusions: Slower hyoid excursion may put older populations at higher risk for aspiration in case of illness or accident. The preventive approach is essential.
