Brief Summary

Twenty-three healthy volunteers (9 men and 14 women; mean age, 27.6 years) participated in this study. A new device was developed that could evaluate the up-down movement of the posterior part of the tongue in a non-invasive manner. The experimental tasks were as follows: (i) /a/ pronunciation for 1 s followed by /ka/ pronunciation (a-ka task), (ii) /a/ pronunciation for 1 s followed by /ga/ pronunciation (a-ga task) and (iii) /a/ pronunciation for 1 s followed by a voluntary push-up movement of the posterior part of the tongue (a-lift task). Maximum upward velocity in the a-ga task was larger than that in the a-ka task (P < 0.05). The a-lift task showed the highest tongue lift range among the three tasks, and the a-ga task showed a higher range than that of the a-ka task (P < 0.05). This study revealed that precise quantification of the motility of the posterior part of the tongue, which would be useful in rehabilitation of articulation and/or swallowing, could be achieved using this new device in a non-invasive manner.
