声学咽道学（Acoustic pharynometry, APh）是一种利用声波反射来量化口咽道结构的方法，常用于睡眠呼吸暂停的诊断和研究。最小横截面积（APh）的标准预设输出是可靠的。然而，通过对特定呼吸任务进行后处理措施，APh数据还可以揭示口腔长度、口腔容积、咽长和咽容积。考虑到这些措施可能在吞咽困难的研究中有用，这些措施的可靠性是未知的，是当前研究的重点。10名年轻健康女性志愿者每隔一周完成两次口腔长度、口腔体积、咽部长度和咽部体积的APh数据收集。计算双向混合类内相关系数，建立组内信度、组间信度和重测信度。结果显示，所有口咽道参数的评分者内部和评分者之间的一致性非常好。口腔长度和口腔体积的复测一致水平表明，这些参数适用于监测个体的变化。在组水平分析中，所有参数被认为具有可接受的重测值。
Acoustic Pharyngometry (APh) is a method for quantifying oropharyngeal tract configuration using sound wave reflection and is commonly used in diagnostics and research of sleep apnea. The standard preset output of APh (minimal cross-sectional area) has been established as reliable. However, by conducting post-processing measures on specific breathing tasks, APh data can also reveal oral length, oral volume, pharyngeal length and pharyngeal volume. Given that these measures may have utility in dysphagia research, the reliability of these measures is unknown and is the focus of the current study. 10 young healthy female volunteers completed two sessions of APh data collection to obtain measures of oral length, oral volume, pharyngeal length and pharyngeal volume one week apart. Two-way mixed intra-class correlation coefficients were calculated to establish intra-rater reliability, inter-rater reliability and test-retest reliability. Results revealed excellent levels of agreement within and across raters for all oropharyngeal tract parameters. Levels of test-retest agreement for oral length and oral volume indicated these parameters are appropriate for monitoring change within an individual. All parameters were deemed to have acceptable test-retest values as outcome measures in group-level analysis.
