About the study
The goal of this a clinical trial is to test the effect of a pharyngeal exerciser in rehabilitation of pharyngeal phase of swallowing in patients with dysphagia. The main question it aims to answer is:
•Does application of pharyngeal exerciser improve swallowing as evidenced by need for prescribed intervention for dysphagia (maneuvers, exercises or dietary modification to prevent aspiration).
Participants will:
* Perform barium swallows in lateral view fluoroscopy * Over a six-week period, perform thrice daily sessions of swallowing with an external, laryngeal restriction device covering the larynx * Return for another fluoroscopic barium swallow study
