虽然努力吞咽和Mendelsohn动作通常用于吞咽障碍康复，但对它们对舌腭压力产生的影响知之甚少。本研究旨在探讨用力吞咽和门德尔松动作对舌压产生的影响。14名健康志愿者（10名男性，4名女性;年龄范围= 21-41岁）参加了研究。舌压力在干吞咽，水吞咽，用力吞咽，和门德尔松动作进行了测量，使用传感器片系统上的硬腭上的五个测量点。比较四种任务的顺序、持续时间、最大值和各测量点的舌压积分值。舌压的起始在后圆周部分首先发生在门德尔松动作，在前正中部分是早于其他部分的努力吞咽。在所有测量点，舌压持续时间显着长于门德尔松动作比其他任务。用力吞咽对增加舌压最有效。舌压积分值在门德尔松动作时的后环部和用力吞咽时的正中部有增加的趋势。这些结果表明，舌压力增加沿着广泛的一部分，在努力吞咽，因为锚的舌运动强调在前面的一部分，硬腭。门德尔松动作提供了延长和加强舌腭接触的后圆周部分，这可能是重要的舌骨喉提升吞咽。
Although effortful swallow and the Mendelsohn maneuver are commonly used in dysphagia rehabilitation, little is known about their effects on tongue-palate pressure production. The purpose of this study was to investigate the effects of effortful swallow and the Mendelsohn maneuver on tongue pressure production. Fourteen healthy volunteers (10 men, 4 women; age range = 21-41 years) participated. Tongue pressures during dry swallow, water swallow, effortful swallow, and the Mendelsohn maneuver were measured using a sensor sheet system with five measurement points on the hard palate. Sequential order, duration, maximal magnitude, and the integrated value of tongue pressure at each measurement point were compared among the four tasks. Onset of tongue pressure at the posterior-circumferential parts occurred first in the Mendelsohn maneuver; that at the anterior-median part was earlier than at other parts in the effortful swallow. At all measurement points, tongue pressure duration was significantly longer in the Mendelsohn maneuver than in other tasks. Effortful swallow was most effective in increasing tongue pressure. The integrated value of tongue pressure at the posterior-circumferential parts in the Mendelsohn maneuver and at the median parts in the effortful swallow showed a tendency to increase. These results suggest that tongue pressure increases along a wide part of the hard palate in effortful swallow because the anchor of tongue movement is emphasized at the anterior part of the hard palate. The Mendelsohn maneuver provides prolonged and accentuated tongue-palate contact at the posterior-circumferential parts, which might be important for hyoid-laryngeal elevation during swallowing.
