目的：本研究的目的是检查冷冻和混合浓度的丸剂对年轻人和老年人吞咽生理的影响。我们还旨在量化导致吞咽结果变异性增加的因素（即年龄、性别、丸剂类型）。方法：41 名健康成年人（18-85 岁）吞咽了 5 块 5 种不同的丸剂：10 毫升超薄液体、一茶匙冰钡、一茶匙室温布丁、一茶匙冷冻布丁和加巧克力片的超薄钡。所有数据均通过视频透视记录，并进行详细的定时运动学测量。结果：钡冰和冷冻布丁都不会加速吞咽反应。许多健康成年人开始吞咽食团时，其深达梨状窦。超稀液体稠度的吞咽时间运动学与所有其他测试的最大不同，与其他测试的丸剂类型相比，要求年轻和年长的健康个体具有最佳的生理吞咽性能（即更快的反应时间、更长的持续时间）。在每项测量中，老年人的持续时间明显长于年轻人。随着年龄和喉前庭运动学的变化，吞咽运动学的变异性更大。结论：这项研究通过阐明各种吞咽行为的正常变异性并提供用于比较紊乱人群的规范数据，为文献做出了重要贡献。
Purpose: The aim of this study was to examine the effects of frozen and mixed-consistency boluses on the swallowing physiology of younger and older adults. We also aimed to quantify factors that lead to increased variability in swallowing outcomes (i.e., age, sex, bolus type).Method: Forty-one healthy adults (18-85 years old) swallowed 5 blocks of 5 different boluses: 10-ml ultrathin liquid, a teaspoon of iced barium, a teaspoon of room-temperature pudding, a teaspoon of frozen pudding, and ultrathin barium with chocolate chips. All data were recorded with videofluoroscopy and underwent detailed timing kinematic measurements.Results: Neither barium ice nor frozen pudding sped up swallow responses. Many healthy adults initiated swallowing with the bolus as deep as the pyriform sinuses. Swallowing temporal kinematics for ultrathin liquid consistencies are most different from all others tested, requiring the best possible physiological swallowing performance in younger and older healthy individuals (i.e., faster reaction times, longer durations) compared with other bolus types tested. In each measure, older adults had significantly longer durations compared with the younger adults. More variability in swallowing kinematics were seen with age and laryngeal vestibule kinematics.Conclusion: This study provides important contributions to the literature by clarifying normal variability within a wide range of swallowing behaviors and by providing normative data from which to compare disordered populations.
