用途：基于视觉检查，先前的研究记录了健康志愿者在保持吞咽时咽后壁的运动增加。本测压研究调查了在健康志愿者中，保持舌头动作对咽部峰值压力产生、压力产生持续时间和压力斜率测量的即时影响。（平均年龄= 25.8岁，性别平均分布）在3个地点记录：口咽、下咽和食管上括约肌（UES）。峰值振幅，持续时间和压力产生的斜率的措施进行了统计analysis.Results：舌举行吞咽产生较低的咽部峰值压力和较短的咽部压力持续时间相比，控制吞咽。此外，舌头举行吞咽产生较低的UES松弛压力。在传感器之间，与口咽部相比，下咽部的峰值压力较低，压力斜率较陡。几个性别特异性差异被发现咽部峰值压力，压力持续时间，和压力slopes.Conclusions：咽部峰值压力的振幅和持续时间减少可能是由于减少的基础上的舌头收缩在舌头举行吞咽。本文讨论了中心的临床考虑和未来的研究方向。
Purpose: Based on visual inspection, prior research documented increased movement of the posterior pharyngeal wall in healthy volunteers during tongue-hold swallows. This manometric study investigated the immediate effects of the tongue-hold maneuver on pharyngeal peak pressure generation, duration of pressure generation, and pressure slope measurements in healthy volunteers.Method: Pharyngeal pressures from 40 young, healthy individuals (mean age = 25.8 years, gender equally distributed) were recorded at 3 locations: oropharynx, hypopharynx, and upper esophageal sphincter (UES), during normal control and tongue-hold swallows. Measures of peak amplitude, duration, and slope of pressure generation were subjected to statistical analysis.Results: Tongue-hold swallows produced lower pharyngeal peak pressure and shorter pharyngeal pressure durations compared to control swallows. Further, tongue-hold swallows produced lower UES relaxation pressures. Between sensors, peak pressure was lower and pressure slopes were steeper in the hypopharynx compared to the oropharynx. Several gender-specific differences were found for pharyngeal peak pressure, pressure duration, and pressure slopes.Conclusions: Reduced amplitude and duration of pharyngeal peak pressure is likely a result of decreased base of tongue retraction during tongue-hold swallows. Central clinical considerations and future research directions are discussed in this article.
