| Outline of Final Research Achievements |
The purpose of this study was to evaluate the movement of the lips in swallowing objectively using simple and less-invasive method, Motion capture system.
9 healthy males were instructed to swallow a mouthful of 5 mL and 20 mL water samples at a self-decided time. Reflective markers were attached to the right and left corners of the mouth to measure the distance between them and tongue pressure was simultaneously recorded. The maximum tongue pressure, the maximum change of distance between the corners of mouth, and the interval between lip action and tongue action (lip-tongue interval) were calculated. Maximum tongue pressure did not differ significantly between volumes. The change of distance between the corners of mouth was larger, and lip-tongue interval was significantly shorter, with the larger volume of a mouthful.These results indicate that the lip movement during swallowing was able to be evaluated quantitatively.
