Abstract

Objective: The aim of this study was to determine (a) whether submental electrical stimulation could induce hyolaryngeal movement in healthy adults, (b) the effect of submental surface electrical stimulation on hyolaryngeal movement during stimulated swallows in comparison to nonstimulated swallows, and (c) the effect of submental surface electrical stimulation on vestibular closing both during stimulated swallows and stimulation at rest. Methods: Seven healthy participants with a mean age was 51 ± 5.6 years were included in this study. Each participant received submental neuromuscular electrical stimulation and was given 5 mL of liquid barium to swallow both with and without stimulation. Six randomized trials were recorded—3 with submental surface stimulation and 3 without stimulation with at least one sham stimulation swallow trial at rest. Trials were recorded via videofluoroscopy. Results: A total of 82 trails were recorded. The results of this study indicated (a) there was a hyoid movement as a result of submental stimulation, (b) no laryngeal movement occurred as a result of stimulation, and (c) the vestibule opening size was larger during stimulated swallows as compared with nonstimulated swallows. Conclusion: This study shows that there is increased risk of aspiration with submental stimulation as a result of increased vestibular opening following submental neuromuscular electrical stimulation.

心理下表面神经肌肉刺激对健康志愿者在休息和吞咽时喉前庭开放的影响

目的：本研究的目的是确定（a）颏下电刺激是否能诱导健康成年人的舌喉运动；（b）与非刺激燕子相比，颏下表面电刺激对刺激燕子舌喉运动的影响，（c）颏下表面电刺激对受刺激吞咽和休息时前庭闭合的影响。方法：本研究包括7名平均年龄为51±5.6岁的健康参与者。每位参与者接受颏下神经肌肉电刺激，并给予5毫升液体钡，在有刺激和无刺激的情况下吞咽。记录了6项随机试验——3项进行了颏下表面刺激，3项未进行刺激，至少进行了一项休息时的假刺激吞咽试验。试验通过视频荧光镜记录。结果：共记录了82条轨迹。这项研究的结果表明：（a）颏下刺激导致舌骨运动，（b）刺激未导致喉部运动，（c）与未刺激的燕子相比，受刺激的燕子前庭开口较大。结论：这项研究表明，由于颏下神经肌肉电刺激后前庭开口增加，颏下刺激会增加误吸的风险。
