尽管已知吞咽运动会随着年龄的增长而变化，但将食团从口腔推入咽部的舌头压力与年龄相关的差异尚未在生理条件下进行研究。我们假设吞咽过程中的舌头压力会随着年龄的增长而变化，并使用具有 5 个测量点的 0.1 毫米厚的传感器片，在年轻人和老年人有齿状个体吞咽 15 毫升水时测量舌头压力。两组在每个点上都表现出相似的舌头压力产生顺序。然而，与年轻组相比，老年组在每个点上表现出更长的持续时间，硬腭前正中部分的最大强度更低，硬腭圆周部分的最大强度更高。这些结果提供了自然吞咽过程中舌头运动与年龄相关的变化的第一个定量证据，这可能归因于口咽部的肌肉减弱和形态变化。
Although swallowing movement is known to change with aging, age-related differences in the tongue pressure for propelling a bolus from the oral cavity into the pharynx have yet to be investigated in a physiological condition. We hypothesized that tongue pressure during swallowing changed with aging and, using a 0.1-mm-thick sensor sheet with 5 measuring points, measured it while a 15-mL quantity of water was swallowed by young and elderly dentate individuals. Both groups showed a similar order of tongue pressure production at each point. However, the elderly group showed longer duration at each point, lower maximal magnitude in the anterio-median part of the hard palate, and higher magnitude in the circumferential parts of the hard palate than the young group. These results provide the first quantitative evidence of the age-related changes in tongue movement during natural swallowing, which could be attributed to muscle weakening and morphological changes in the oropharynx.
