Influence of Aging on Movement of the Hyoid Bone and Epiglottis during Normal Swallowing: A Motion Analysis

The age-related effects on various aspects of swallowing have been reported in studies on the temporal relationship between hyolaryngeal movement and bolus location, as well as the extent of hyolaryngeal movement. However, few studies have described the temporal and spatial relationships concurrently.The main purpose of this study was to define the kinematics of the hyoid bone and epiglottis, during swallowing, on the temporal and spatial...
