Oropharyngeal pressure during swallowing was studied in a total of 40 healthy adult males and females in two age groups (21-27 yr and 62-75 yr). Effects of bolus volume, bolus viscosity, age, and gender were analyzed, and dry and bolus swallows were compared. The duration of the intrabolus pressure, reflecting the pressure exerted by the tongue on the bolus and preceding the generation of the pharyngeal pressure, was significantly affected by bolus volume. The duration of oropharyngeal pressure was affected by age, gender, and bolus type (bolus vs. dry swallow). Peak oropharyngeal pressure was not affected by any of the test factors, although there was a tendency for older subjects to have higher pressures than young subjects.
对总共40名健康成年男性和女性进行了吞咽过程中口咽压力的研究，这些受试者分为两个年龄组（21 - 27岁和62 - 75岁）。分析了食团体积、食团粘度、年龄和性别的影响，并比较了干性吞咽和食团吞咽。反映舌头对食团施加压力并先于咽压力产生的食团内压力持续时间，受食团体积的显著影响。口咽压力持续时间受年龄、性别和食团类型（食团吞咽与干性吞咽）的影响。尽管老年受试者的压力有高于年轻受试者的趋势，但口咽压力峰值不受任何测试因素的影响。
