在液体的口腔处理过程中的感觉功能被认为在告知吞咽运动行为对丸剂的流动特性的定制方面起关键作用。除了味觉感受器之外，口腔和舌头还容纳三叉神经感受器，其支持对食团大小、形状（立体感）、质量、温度和运动的感觉检测。最近的研究表明，健康的成年人随着年龄的增长而失去舌头的力量。然而，人们对舌头感觉功能的变化知之甚少，这些变化可归因于年龄，或与强度下降有关。在这项研究中，我们探讨了健康的年轻人和老年人的舌触觉敏锐度，并测量触觉敏锐度和舌强度的措施之间的关系。结果表明，与年龄相关的舌触觉敏锐度的下降，不能解释的变化，在tongue strength.Practical ApplicationsSensory运动的相互作用是一个感兴趣的主题，在理解的处理活动，发生在口腔进食和吞咽。在本文中，我们探讨了一个测试的感觉敏锐度在口腔中，舌头是用来“阅读”特氟龙条上的浮雕字母。我们的问题是确定这项任务的感觉敏锐度是否会随着年龄的增长而下降，或者与年龄相关的舌头强度下降。我们确定，老年人执行这项任务的准确性较低，这表明随着年龄的增长，口腔感觉功能发生了一些变化。然而，这些变化与舌强度无关。研究结果表明，在这项研究中测试的感觉辨别任务中，力量并不起主要作用。
Sensory function during the oral processing of liquids is thought to play a key role in informing the tailoring of swallowing motor behaviors to the flow characteristics of the bolus. In addition to taste receptors, the mouth and tongue house trigeminal nerve receptors that support the sensory detection of bolus size, shape (stereognosis), mass, temperature and movement. Recent studies suggest that healthy adults lose tongue strength with advancing age. However, little is known about changes in the sensory function of the tongue attributable to age, or associated with reductions in strength. In this study, we explored lingual tactile acuity in healthy young and older adults, and measured the relationship between tactile acuity and measures of tongue strength. The results showed an age‐related reduction in lingual tactile acuity that was not explained by variations in tongue strength.Practical ApplicationsSensory motor interactions are a topic of interest in understanding the processing activities that take place in the mouth during eating and swallowing. In this paper, we explore a test of sensory acuity in the mouth, in which the tongue is used to “read” embossed letters on Teflon strips. Our questions were to determine whether sensory acuity for this task declines with age, or with age‐related reductions in tongue strength. We determined that older people perform this task with less accuracy, suggesting some changes in oral sensory function with age. However, these changes were not related to tongue strength. The findings suggest that strength does not play a major role in the kind of sensory discrimination task tested in this study.
