Abstract

The purpose of this study was to establish parameters regarding the total distance and duration of hyoid bone displacement during water and sour boluses of regular and nectar-thick consistencies among young and older adults. Distance and duration parameters for hyoid bone displacement in adults will assist in safe and accurate diagnoses of dysphagia. Thirty-two young adults and five older adults were assessed via an ultrasonic procedure. Following the capture of a swallow, hyoid bone measurements and durations were obtained through frame-by-frame analysis. Results indicated that aging did not significantly affect the distance of hyoid bone movement when participants were presented with water, nectar-thick water, cranberry juice, and nectar thick-cranberry juice. Further analysis indicated that mean hyoid bone movement for the water condition was longer than the mean movement of all other conditions. Any change observed in duration of hyoid bone displacement was determined to be insignificant across all conditions.
