背景：吞咽时舌的功能是根据食团体积进行调节，然而，相关的舌动力学尚不清楚。目的我们的目的是阐明吞咽过程中舌头运动和舌压如何随着丸剂体积而变化。方法16名健康志愿者（年龄29.5 ± 3.8岁;男12名，女4名）。两个电磁关节造影标记，分别在舌头的前部和后部，以测量运动。将具有五个压力敏感点的传感器片附接到硬腭以测量舌头压力。参与者被要求吞咽3毫升和10毫升水。分析舌压的运动轨迹、最大速度、舌压与硬腭接触前的垂直位移、舌压的最大值和持续时间。结果舌旋转在矢状面上的出现率在吞咽3 ml水时明显高于吞咽10 ml水时，舌后部旋转的出现率明显高于前部。吞咽10 ml水时的最大速度和垂直位移显著大于吞咽3 ml水时的最大速度和垂直位移。3 ml和10 ml之间的舌压最大值和舌压最大持续时间均无显著差异。结论单次剂量影响舌运动模式，但舌压无差异。
Background The tongue functions by modulating according to bolus volume when swallowing; however, associated tongue dynamics are unclear. Objective We aimed to clarify how tongue motion and tongue pressure change with bolus volume during swallowing. Methods Sixteen healthy volunteers (age 29.5 +/- 3.8 years; 12 males, 4 females) were recruited. Two electromagnetic articulography markers were attached, one each on the anterior and posterior parts of the tongue, to measure motion. A sensor sheet, with five pressure-sensitive points, was attached to the hard palate to measure tongue pressure. Participants were asked to swallow 3 ml and 10 ml of water. Motion trajectory, maximum velocity, vertical displacement just before contact with the hard palate, and maximum magnitude and duration of tongue pressure were analysed. Results Tongue rotation was observed in the sagittal plane; its rate of appearance was significantly higher when swallowing 3 ml of water than when swallowing 10 ml, and the rate of rotation at posterior part was significantly higher than at the anterior part. The maximum velocity and vertical displacement were significantly greater when swallowing 10 ml of water than those when swallowing 3 ml of water. There was no significant difference in either the maximum magnitude of tongue pressure or maximum duration of tongue pressure between 3 ml and 10 ml. Conclusion Bolus volume influenced the pattern of tongue motion; however, there was no difference in tongue pressure.
