The purpose of this project was to examine swallowing patterns using ultrasound technology. Ultrasound research in the realm of swallowing is sparse, yet has potential clinical application. In using ultrasound, this study outlines a protocol for utilization of a hand-held probe and reinforces a particular protocol described in the literature. Real-time ultrasound recordings of swallows for 21 adult subjects were made. Baseline swallow patterns were compared to swallows after implementation of one therapeutic intervention common in both feeding and myofunctional therapy, and one intervention more commonly associated with myofunctional therapy. Changes in swallowing patterns are described, and similarities of interventions across the two professions are discussed. Participants with oromyofunctional disorder are compared to a group with typical swallowing and differences in ultrasound patterns are described. Analysis includes relative duration of swallowing stages compared to the total duration of the swallow, measurements of tongue height after implementation of the interventions, and the number of swallows required for the bolus to be cleared from the oral cavity.
Learner Outcomes: At the completion of this presentation, participants will be able to identify oral structures on an ultrasound display.
