Evaluation of tongue pressure and laryngeal movement during swallowing

本研究的目的是探讨吞咽水时舌接触腭和舌骨运动之间的顺序协调。我们在硬腭上应用了一个传感器片来测量舌接触压力，在额颈上应用了一个弯曲传感器来监测喉部运动，以评估吞咽过程中两个动作之间的协调性。舌压和舌骨-喉位移的顺序是：舌压在舌骨轻微运动后产生，并接近舌骨抬高，然后在舌骨稳定在最前上方位置时达到最大值，并在舌骨下降开始时停止。

This study was aimed to investigate the sequential coordination between tongue contact against palate and hyoid movement during swallowing water. We applied a sensor sheet on the hard palate to measure tongue contacting pressure and a bend sensor on the frontal neck to monitor the laryngeal movement for assessing the coordination between both actions during swallowing. The sequential order of tongue pressure and hyoid-laryngeal excursion was successfully displayed: tongue pressure was produced after the hyoid slight movement and closely to the hyoid elevation, then reached maximal value when the hyoid began stable in the most anterior-superior position, and ceased concurrently with the onset of hyoid descending.
