大剂量体积已经被广泛研究，并且研究已经证明了对吞咽和吞咽障碍的各种生理影响。据我们所知，口服药丸量的感知尚未与正常的衰老过程相关。研究表明，随着年龄的增长，许多感觉变化，一些在口腔内，吞咽功能随着年龄的变化已经被定义。随着年龄的增长，知觉在口咽吞咽中的作用需要进一步研究。本研究的目的是建立液体量和口腔知觉之间的心理物理关系，并检查随年龄的变化。健康的年轻人和老年人进行了前瞻性评估，使用的幅度估计任务区分五个体积的水随机输送到口腔。结果表明，与年轻的健康成年人相比，老年参与者需要四倍的液体体积增加才能感知到体积感知的大约两倍增加。口腔中的感觉感受器提供了一个反馈回路，该反馈回路调节吞咽运动反应，使得其对于丸剂的大小和稠度是最佳的。随着年龄的变化，丸量的感知与其他感知的变化是一致的，并可能提供有价值的信息，在未来的感觉神经康复策略。
Bolus volume has been widely studied, and research has demonstrated a variety of physiological impacts on swallowing and swallowing disorders. Oral perception of bolus volume has not, to our knowledge, been investigated in association with normal ageing processes. Research suggests many sensory changes with age, some within the oral cavity, and changes in swallowing function with age have been defined. The role of perception in oropharyngeal deglutition with age requires further investigation. The purpose of this study was to establish the psychophysical relationship between liquid volume and oral perception and examine changes with age. Healthy young and older adults were prospectively assessed using a magnitude estimation task differentiating five volumes of water delivered randomly to the oral cavity. Results suggest a fourfold increase in liquid volume is required by older participants to perceive an approximate twofold increase in the perception of volume compared with younger healthy adults. Sensory receptors in the oral cavity provide a feedback loop that modulates the swallowing motor response so that it is optimal for the size and consistency of the bolus. Changes in perception of bolus volume with age are consistent with other perceptual changes and may provide valuable information regarding sensorineural rehabilitation strategies in the future.
