本研究的目的是评估健康成人进行声门上吞咽（SS）和超声门上吞咽（SSS）时舌压产生的状态，并研究这些吞咽动作对吞咽口部阶段的影响。参与者为19名健康人。吞咽过程中舌压对硬腭的测量使用舌压传感器片系统与五个压力敏感点。任务包括通过正常湿吞咽、SS和SSS吞咽5 mL水，用于分析的参数为吞咽过程中舌压的持续时间、最大幅度和积分值。舌压力的持续时间显着较长的前中部分的硬腭在SS和SSS比正常湿吞咽。最大振幅在SS时仅在硬腭后部显著增加，但在SSS时在所有点均显著增加。积分值在SS期间仅在硬腭的后正中部分显著增加，但在SSS期间除了硬腭的中正中部分之外的所有点均显著增加。SSS期前正中和后环部的最大幅度和积分值也显著高于SS期。这些结果表明，这两个吞咽动作，这主要是已知的技术，以保护气道，也起到加强舌压力之间的接触产生的舌头和硬腭在吞咽过程中，这种效果是更明显的SSS。
The objectives of this study were to evaluate the state of tongue pressure production during supraglottic swallow (SS) and super-supraglottic swallow (SSS) performed by healthy adults, and to investigate the effects of these swallowing maneuvers on the oral stage of swallowing. The participants were 19 healthy individuals. Tongue pressure against the hard palate during swallowing was measured using a tongue pressure sensor sheet system with five pressure-sensitive points. The tasks comprised swallowing 5 mL of water by normal wet swallow, SS, and SSS, and the parameters for analysis were the duration, the maximal magnitude, and the integrated value of tongue pressure during swallowing. The duration of tongue pressure was significantly longer at the anterior-median part of the hard palate during both SS and SSS than with normal wet swallow. The maximal magnitude increased significantly only at the posterior part of the hard palate during SS, but at all points during SSS. The integrated value increased significantly only at the posterior-median part of the hard palate during SS, but at all points except the mid-median part of the hard palate during SSS. The maximal magnitude and integrated value were also significantly higher at the anterior-median and posterior circumferential parts during SSS than during SS. These results show that these two swallowing maneuvers, which are known primarily as techniques to protect the airway, also function to strengthen the tongue pressure produced by the contact between the tongue and the hard palate during swallowing and this effect is more pronounced during SSS.
