To obtain a series of objective criteria associated with pharyngeal swallowing function using dynamic swallow study in Chinese adults.
Dynamic videofluoroscopic swallow studies were performed on 80 normal adult volunteers. There were 40 males and 40 females aged from 20 to 60 years old. Measurement software Avidemux 2.5 and Image J were used to measure the objective parameters which were closely related to the pharyngeal swallowing function in the swallowing process, such as maximum displacement of the hyoid bone (HmaxD), pharyngeal transit time (PTT), pharyngeal constriction ratio(PCR), and maximum opening of the esophageal entrance (EEmax).
In the 80 adults, the HmaxD, PTT, PCR, and EEmax were (1.91 ± 0.48) cm (x(-) ± s), (0.82 ± 0.15) s, 94.9% ± 3.41%, and (0.91 ± 0.05) cm respectively. The HmaxD of the male (2.04 ± 0.46) cm was significantly larger than that of the female (1.78 ± 0.47) cm (t = 2.44, P = 0.017), but the PTT, PCR, and EEmax had no significant difference between different gender and age groups (P > 0.05).
Objective parameters of the HmaxD, PTT, PCR, and EEmax during swallowing are obtained in Chinese adults. These data are important for assessment of the swallow function and these data provide a foundation for further research on assessment of swallowing function in Chinese.
通过对中国成年人进行动态吞咽研究，获取一系列与咽吞咽功能相关的客观标准。
对80名正常成年志愿者进行动态视频荧光吞咽研究。其中男性40名，女性40名，年龄在20至60岁之间。使用测量软件Avidemux 2.5和Image J测量吞咽过程中与咽吞咽功能密切相关的客观参数，如舌骨最大位移（HmaxD）、咽传输时间（PTT）、咽收缩率（PCR）和食管入口最大开口度（EEmax）。
在80名成年人中，HmaxD、PTT、PCR和EEmax分别为（1.91±0.48）cm（x(-)±s）、（0.82±0.15）s、94.9%±3.41%和（0.91±0.05）cm。男性的HmaxD（2.04±0.46）cm显著大于女性（1.78±0.47）cm（t = 2.44，P = 0.017），但PTT、PCR和EEmax在不同性别和年龄组之间无显著差异（P>0.05）。
获取了中国成年人吞咽过程中HmaxD、PTT、PCR和EEmax的客观参数。这些数据对于吞咽功能评估具有重要意义，为进一步研究中国人吞咽功能评估提供了基础。
