Objective To explore the relationships among tongue pressure, hyoid composite movement and pharynx phase activity among stroke survivors with dysphagia. Methods Videofluoroscopy was used to observe the swallowing performance of 13 stroke survivors with dysphagia. Their tongue pressure was also measured. Correlations were sought among the tongue pressure, hyoid motion, the pharynx contraction ratio and the duration of upper oesophageal sphincter opening. Results Tongue pressure was found to be significantly positively correlated with the duration of upper oesophageal sphincter opening. The distance of forward movement of the hyoid and the pharynx contraction ratio were also significantly positively correlated. Conclusion The tongue muscle and hyoid activity can affect the activity in the pharyngeal phase of swallowing. Key words: Stroke; Dysphagia; Tongue pressure; Videofluoroscopy; Hyoid motion
