到目前为止，在体检、放射学检查、测压和宫颈听诊中对吞咽进行了评估。放射摄影术主要显示口腔和咽部功能的定性方面，而定量方面主要通过测压来记录。为了在不使用侵入性方法或辐射的情况下定量评估吞咽，我们应用了一种饮用水的联合测试，即重复口腔吸咽试验(ROSS)。这项测试提供了可靠的吸气压力、推进量、口腔和咽部吞咽重要事件的时间以及呼吸的测量。描述了这项测试，并介绍了292名健康的、非吞咽困难的受试者的结果。我们发现，在单次吞咽时，平均团注容量为25.6±-8.5毫升，而在应激(强迫、重复吞咽)时，平均团注容量为21.1±-8.2毫升。在强迫重复吞咽时，吸气时间(r(2)=0.55)比最大吸气压力(r(2)=0.04)与吸气时间的相关性更强，说明吸气时间比吸气压力更重要。口咽通过时间缩短：单次吞咽0.56±0.36秒，强迫重复吞咽0.23±0.11秒，变异系数降低(分别为48%和%)，提示强迫反复吞咽的咽部功能有更自动化的神经过程。在10%的受试者中，吞咽后的呼吸开始于吸气，但与测试中其他变量的偏差无关。因此，吞咽后的灵感必须被认为是正常的。罗斯试验提供了一种快速、简便的吞咽定量评估方法。
Swallowing has hitherto been evaluated during physical examination, radiologic barium studies, manometry, and cervical auscultation. Radiography principally demonstrates qualitative aspects of oral and pharyngeal function, whereas quantitative aspects have primarily been documented by manometry. To evaluate swallowing quantitatively, without using invasive methods or radiation, we have applied a combined test of water drinking, i.e., the Repetitive Oral Suction Swallow test (ROSS). The test provides reliable measurements of suction pressure, bolus volume, timing of important events in oral and pharyngeal swallow, and respiration. The test is described and results from 292 healthy, non-dysphagic subjects are presented. We found a mean bolus volume of 25.6 +/- 8.5 mi during single swallow and 21.1 +/- 8.2 mi during stress (forced, repetitive swallow). During forced, repetitive swallow, the bolus volume was more strongly associated with suction time (r(2) = 0.55) than with peak suction pressure (r(2) = 0.04), indicating that suction time is more important than suction pressure in determining the bolus volume. The oral-pharyngeal transit time decreased: single swallow 0.56 +/- 0.36 sec, forced repetitive swallow 0.23 +/- 0.11 sec, as did the coefficient of variation (48% and 64%, respectively) indicating a more automatic neural process for pharyngeal function in forced, repetitive swallow. The postswallow respiration started with inspiration in 10% of studied individuals, but did not correlate with deviations in other variables in the test. Thus, postswallow inspiration must be considered as normal. The ROSS test offers a rapid and easy quantitative assessment of swallowing.
