目的：比较持舌吞咽法对健康青年和老年研究志愿者咽压产生的影响。方法：68名健康的研究志愿者（年轻，n = 34，平均年龄= 26.8岁，SD = 5.5；老年，n = 34，平均年龄= 72.6岁，SD = 4.8；性别平等）每人进行5次不费力的唾液吞咽和5次舌抓吞咽。在两种吞咽状态下，使用口咽、下咽和食管上括约肌（UES）水平的固体咽压测量法研究咽压的振幅和持续时间。结果：在两个咽部水平，与唾液吞咽相比，舌吞产生更低的峰值压力。在持舌吞咽过程中，老年人的UES松弛压力增加，而年轻人的UES松弛压力则呈下降趋势。老年个体在控制吞咽口咽和下咽时产生的压力比年轻个体长。结论：持舌手法对青年和老年人口咽压和下咽压的影响相似，而对UES峰松弛压的影响在不同年龄组之间存在差异。咽部峰值压力降低和UES松弛压力增加强调了这样一种观念，即当丸剂存在时，不应进行舌握吞咽。长期训练的效果仍有待研究。
Purpose: To compare the effects of the tongue-hold swallowing maneuver on pharyngeal pressure generation in healthy young and elderly research volunteers.Method: Sixty-eight healthy research volunteers (young, n = 34, mean age = 26.8 years, SD = 5.5; elderly, n = 34, mean age = 72.6 years, SD = 4.8; sex equally represented) performed 5 noneffortful saliva swallows and 5 tongue-hold swallows each. Amplitude and duration of pharyngeal pressure were investigated during both swallowing conditions with solid-state pharyngeal manometry at the level of the oropharynx, hypopharynx, and upper esophageal sphincter (UES).Results: At both pharyngeal levels, tongue-hold swallows produced lower peak pressure compared with saliva swallows. During tongue-hold swallows, UES relaxation pressure was increased in the elders, whereas the younger group displayed a trend toward reduced relaxation pressure. Elderly individuals produced pressure longer during control swallows in the oropharynx and hypopharynx than young individuals.Conclusions: The tongue-hold maneuver affects oropharyngeal and hypopharyngeal pressure in the young and elders in similar ways, whereas effects on UES peak relaxation pressure differ between age groups. Reduced pharyngeal peak pressure and increased UES relaxation pressure underscore the notion that tongue-hold swallows should not be performed when bolus is present. Long-term training effects remain to be investigated.
