项目摘要

Dysphagia with frequent aspiration is associated with an increased risk for subsequent pneumonia. Aspiration pneumonia in the elderly may be caused by a decrease in the swallowing function. The aim of this study was to discuss the influence of body position on swallowing function.Following informed consent, 10 healthy, fully dentate males (average age : 29.5 3.6 years old) were selected as subjects. Tongue movements and swallowing sounds were observed and recorded using general-purpose ultra-sound diagnostic system. Tongue movement and swallowing sounds were analyzed by plotting five inflection points (T1, T2, T3, T4 and T5) of the tongue movement curve and two beginning points of swallowing sounds (S1 and S2) using a digitizer. The test food was made by dissolving Mousse Up (Food Care Ltd. Japan) of 6 g into 30 ml water. Subjects were directed to swallow a test food under 3 body positions ; sitting position, 30^o lying position, lying position. Statistical analysis was performed by one-way analysis of variance (ANOVA) and the Duncan test.The times from the beginning point of the swallowing to T3, T4, S1 and S2 were significant extended (p < 0.05). The time from S1 to T4 was significant extended (p < 0.005). There was a significant correlation between T4 and S1, T4 and S2 statistically (p < 0.05).In the "lingual stage", the lingual edges appose the hard plate anteriorly and laterally as tongue contact. In our study, we judged T4 to be the end of this stage and the bolus would be squeezed toward the oropharynx. In the "pharyngeal stage", the tongue approximates the posterior pharyngeal wall resulting in a tight velopharyngeal seal. The epiglottis will be shut in anticipation of the bolus. In our study, we judged S1 to be the beginning of this sound.From this study, it was suggested that the body positions influence on swallowing function, and also suggested that our analyzing method could be useful for evaluation of the swallowing function.

频繁误吸导致的吞咽困难会增加随后患肺炎的风险。老年人吸入性肺炎可能是由于吞咽功能下降引起的。本研究的目的是探讨体位对吞咽功能的影响。经知情同意后，选择10名健康、完全有齿状的男性（平均年龄：29.5±3.6岁）作为研究对象。使用通用超声诊断系统观察并记录舌头运动和吞咽声音。通过使用数字化仪绘制舌头运动曲线的五个拐点（T1、T2、T3、T4和T5）和吞咽声音的两个起点（S1和S2）来分析舌头运动和吞咽声音。测试食品是将6克Mousse Up（日本Food Care Ltd.）溶解到30毫升水中制成的。受试者被指示以 3 种身体姿势吞咽测试食物；坐姿、30^o 卧姿、卧姿。采用单因素方差分析(ANOVA)和邓肯检验进行统计分析。从吞咽开始点到T3、T4、S1和S2的时间显着延长(p < 0.05)。从 S1 到 T4 的时间显着延长 (p < 0.005)。 T4与S1、T4与S2之间在统计学上有显着相关性(p < 0.05)。在“舌期”，舌缘向前和侧向贴合硬板作为舌接触。在我们的研究中，我们判断 T4 是该阶段的结束，丸剂将被挤向口咽部。在“咽阶段”，舌头接近咽后壁，导致腭咽部紧密密封。会厌将因预期推注而关闭。在我们的研究中，我们判断S1是这个声音的开始。从这项研究中，表明身体姿势对吞咽功能的影响，也表明我们的分析方法可用于评估吞咽功能。
