Primary outcomePrimary: Change in Swallow Response Time for 5 cc Thin Liquid Swallows — 2; 2; 4; 3 participants
Summary
People with swallowing impairment experience particular difficulty swallowing thin liquids safely; the fast flow of liquids makes them difficult to control. The tongue plays a critical role in containing liquids in the mouth, channeling the direction of their flow towards the pharynx (throat) and controlling their flow along that channel. The investigators are engaged in a program of research to better understand tongue function in swallowing, particularly with respect to controlling the flow of liquids. In this study the investigators will compare two different tongue-pressure resistance training protocols, to determine whether a protocol that emphasizes strength-and-accuracy or one that emphasizes pressure timing work better for improving liquid flow control in swallowing.

Eligibility Criteria
Inclusion Criteria
- Individuals with dysphagia characterized by prolonged swallow response duration for 5 cc boluses of thin liquid (i.e., > 350 ms, confirmed in videofluoroscopy).
Exclusion Criteria
- premorbid reported history of swallowing, motor speech, gastro-esophageal or neurological difficulties.
- prior history of surgery to the speech apparatus (other than routine tonsillectomy or adenoidectomy).
