BACKGROUND
Chin-up posture is frequently used to manage oral dysphagia after head and neck cancer. This prospective study investigates the effects of chin-ups on the sequence of pharyngeal swallowing events.
METHODS
Twelve healthy young adults performed 45 consecutive swallows of 5 mL water across 3 phases on videofluoroscopy: 5 swallows in the neutral head position; 30 swallows during chin-up posture; and 10 swallows in the neutral head position. Swallowing kinematic and bolus flow measures for 9 swallowing events were recorded. Linear trends were analyzed across 30 chin-up swallows; pairwise comparison was used to compare the 3 phases.
RESULTS
Time to hyoid peak and laryngeal vestibule closure changed abruptly during chin-up swallowing compared to the initial neutral position. No measure changed across 30 chin-up swallows. Time of hyoid burst decreased upon returning to the neutral position.
CONCLUSION
Our findings indicate that chin-up posture challenges the pharyngeal sequence of events for both swallowing kinematics and bolus flow. © 2017 Wiley Periodicals, Inc. Head Neck 39: 947-959, 2017.
背景
引体向上姿势常用于头颈癌后口腔吞咽困难的管理。这项前瞻性研究调查了引体向上对咽部吞咽事件顺序的影响。
方法
12名健康的年轻成年人在视频荧光透视下分三个阶段连续吞咽45次5毫升水：头部中立位吞咽5次；引体向上姿势下吞咽30次；头部中立位吞咽10次。记录9次吞咽事件的吞咽运动学和食团流动测量值。分析30次引体向上吞咽过程中的线性趋势；采用两两比较法比较三个阶段。
结果
与初始中立位相比，引体向上吞咽过程中舌骨峰值和喉前庭关闭时间突然改变。30次引体向上吞咽过程中各项测量值均无变化。恢复到中立位时舌骨爆发时间缩短。
结论
我们的研究结果表明，引体向上姿势对吞咽运动学和食团流动的咽部事件顺序构成挑战。©2017威利期刊公司。《头颈》39: 947 - 959, 2017。
