OBJECTIVE
To present the results of scintigraphic evaluation, using the Gaussian curve fitting method, via 3 parameters of oropharyngeal swallow: (1) pharyngeal transit time, (2) premature pharyngeal entry, and (3) postswallow pharyngeal stasis while ingesting liquid.
DESIGN
A descriptive study.
SETTING
A rehabilitation hospital affiliated with a medical university.
PARTICIPANTS
Eighteen healthy subjects.
INTERVENTION
All 18 subjects received scintigraphic swallow examination to evaluate dynamic swallow process of 5 mL of liquid.
MAIN OUTCOME MEASURES
The Gaussian curve fitting method was used to calculate the pharyngeal transit time, premature pharyngeal entry, and postswallow pharyngeal stasis.
RESULTS
The mean pharyngeal transit time was .71 seconds. The maximal percentage of premature pharyngeal entry was 3%. The maximal percentage of postswallow pharyngeal stasis was 9%.
CONCLUSIONS
The Gaussian curve fitting can be used as an objective and time-saving method to calculate the parameters in scintigraphic swallowing examination. Our results approximate other researchers' reports.
目的
通过口咽吞咽的3个参数，即（1）咽通过时间、（2）咽部过早进入和（3）吞咽后咽部滞留，使用高斯曲线拟合方法呈现闪烁扫描评估结果，同时摄入液体。
设计
描述性研究。
地点
一所医科大学附属康复医院。
参与者
18名健康受试者。
干预措施
所有18名受试者均接受闪烁扫描吞咽检查，以评估5毫升液体的动态吞咽过程。
主要观察指标
采用高斯曲线拟合方法计算咽通过时间、咽部过早进入和吞咽后咽部滞留情况。
结果
平均咽通过时间为0.71秒。咽部过早进入的最大百分比为3%。吞咽后咽部滞留的最大百分比为9%。
结论
高斯曲线拟合可作为一种客观且省时的方法来计算闪烁扫描吞咽检查中的参数。我们的结果与其他研究人员的报告相近。
