The establishment of a new swallowing analysis method

那么，似乎可以期待精度更高的测量仪器的应用。从迄今为止的研究结果来看，PPT波形的频率是了解吞振动声合成的波纹的事实。但波动分量与吞咽功能不可能有明确的对应关系。在吞咽反射的吞咽咽阶段，时间延长的传输时间的营养丸从舌根到会厌，比例的硬度的主题食物的营养丸。然而，它表明，从会厌到食道的传输时间保持固定的速度，目标食物的硬度。看来这样的新知识也应用到了燕食的研制上。同时，PPT作为一种吞咽生理学评价手段，也具有广泛的应用前景。

Then, it seems to be able to expect the application which does the measuring instrument of which the accuracy is higher.From until now research result, the frequency of a PPT wave type is understand the fact swallow vibration sound synthesis rippled. However, it was not possible that the wave component and swallowing function corresponded clearly.In the meantime, this equipment was applied in food physical property. In deglutition reflex in the swallow pharynx stage, the time stretched on transit time of a alimentary bolus from base of tongue to the epiglottis in, proportion to the hardness of the subject food in a alimentary bolus.' However, it be shown by that the transit time from the epiglottis to the gullet keeps the fixed speed the hardness of the subject food. It seems that such new knowledge is also applied to the development of the swallow eclipse. In the meantime, it is regarded as also applying in versatile as a physiological evaluation of the swallow using PPT the future.
