Swallows of 4 bolus volumes (1, 5, 10, 20 ml) were examined in three groups of subjects: 6 subjects 20-29 years of age, 12 subjects 30-59 years of age, and 6 subjects 60-79 years of age. A simultaneous manometric and videofluoroscopic data collection protocol permitted measurement of bolus transit, temporal aspects of the oropharyngeal swallow, and pharyngeal peristalsis. Statistically significant effects of increasing bolus volume were oral transit of the bolus head (decreased) and duration of cricopharyngeal opening (increased). Five measures were significantly changed with increasing age: duration of pharyngeal swallow delay (increased), duration of pharyngeal swallow response (decreased), duration of cricopharyngeal opening (decreased), peristaltic amplitude (decreased), and peristaltic velocity (decreased).
在三组受试者中检查了4种团块体积（1、5、10、20毫升）的吞咽情况：6名年龄在20 - 29岁的受试者、12名年龄在30 - 59岁的受试者和6名年龄在60 - 79岁的受试者。同步测压和视频荧光透视数据收集方案允许测量团块通过情况、口咽吞咽的时间方面以及咽部蠕动。团块体积增加具有统计学显著影响的方面为团块头部的口腔通过时间（减少）和环咽肌开放持续时间（增加）。随着年龄增长，有5项指标发生了显著变化：咽部吞咽延迟持续时间（增加）、咽部吞咽反应持续时间（减少）、环咽肌开放持续时间（减少）、蠕动幅度（减少）和蠕动速度（减少）。
