Rehabilitation for dysfunctions of eating and swallowing should be considered in terms of not only motor but also sensory function. Sensory information from a bolus in the mouth plays an important role in eating and swallowing. Therefore, this study investigated oral stereognosis in 184 healthy adults with normal eating and swallowing function in order to obtain normative data. Oral stereognosis was assessed by using 20 intra-oral test pieces with different shapes. The subjects manipulated the test pieces in the mouth and identified their shapes. At this time, the test scores and response times for answering were recorded. The results revealed differences in oral stereognosis depending on the age of the subjects and the test pieces employed. The younger group had higher test scores and shorter response times than the older group, except for comparisons between the 20s and 30s age groups. In addition, response time was negative correlated with test scores (r = -0.956, P < 0.001). These results indicate that oral stereognosis decreases with age.
对于进食和吞咽功能障碍的康复，不仅应从运动功能方面考虑，还应从感觉功能方面考虑。口腔内食团的感觉信息在进食和吞咽中起着重要作用。因此，本研究对184名具有正常进食和吞咽功能的健康成年人进行了口腔立体感觉测试，以获取规范性数据。通过使用20个不同形状的口腔内测试片来评估口腔立体感觉。受试者在口腔内操作测试片并识别其形状。此时，记录测试分数和回答的反应时间。结果显示，根据受试者的年龄和所使用的测试片不同，口腔立体感觉存在差异。除了20多岁和30多岁年龄组之间的比较外，较年轻组的测试分数更高，反应时间更短。此外，反应时间与测试分数呈负相关（r = -0.956，P < 0.001）。这些结果表明，口腔立体感觉会随着年龄的增长而下降。
