Effects of three techniques designed to improve maximum range of posterior movement of the base of tongue were investigated under videofluoroscopy in 20 subjects. Retraction of the tongue base during 3-ml pudding swallows, tongue pull-back, yawn, and gargle tasks was measured in millimeters, with the second cervical vertebra as a reference point and was judged subjectively as well. The gargle task was the most successful in eliciting most tongue base retraction for the group of subjects, although not in every subject. Gargle also resulted in greater tongue base movement than swallow more often than the other two voluntary tasks. Clinicians' subjective judgment of "most" retracted tongue base position was generally reliable in comparison with actual measurements. The number of repeat swallows on each bolus correlated significantly with the approximate percentage of residue in the valleculae as judged clinically.
在20名受试者中，通过电视荧光透视法研究了三种旨在改善舌根后移最大范围的技术的效果。在3毫升布丁吞咽、拉舌、打哈欠和漱口任务中，以第二颈椎为参考点，测量舌根后缩的毫米数，并进行主观判断。漱口任务在引起大多数受试者舌根后缩方面最为成功，尽管不是每个受试者都如此。与其他两项自主任务相比，漱口导致舌根运动比吞咽更频繁。与实际测量结果相比，临床医生对舌根“最”后缩位置的主观判断通常是可靠的。每次推注时重复吞咽的次数与临床上判断的梨状窝中残留的大致百分比显著相关。
