Nobel Tongue Function Diagnosis Based on Age-specific Maximum Tongue Pressure Standard Value

本研究的目的是建立一种新的基于年龄相关的最大自主舌压标准值(MVTP)的便捷式舌功能诊断方法。在组装了带有一次性口腔探头和便携式设备的实用系统后，在广岛大学牙科伦理委员会的许可下，我们测量了1229名志愿者的MVTP(年龄范围：受试者18-39岁：311，40-59岁：99，60-79岁：429，80岁及以上：390)。除测量MVTP外，对无吞咽障碍体征和症状的受试者进行口腔状态和咀嚼/吞咽功能的检查和访谈，包括重复唾液吞咽试验(RSST)，MVTP各年龄段的平均值为：18~39岁：42±11 kPa，40~59岁：39±12 kpa，60.79岁：32±11 kpa，80岁及以上：23±11 kpa。年龄与MVI‘P呈负相关。对于年龄超过10岁的受试者，在RSST中能吞咽3次及以上者的MVTP(29±12kPa)比能吞咽3次者(21±12kPa)的MVTP更强。综上所述，尽管从有限的角度来看，我们可以方便、安全地诊断与吞咽功能有关的某些定量方面的舌功能

The purpose of this study was to establish a novel handy tongue function diagnosis based on age-specific standard value of maximum voluntary tongue pressure (MVTP). After assembling utility system with disposable intra-oral probe and portable devices that enables us to measure tongue pressure in diversified environments supposed in such as epidemiologic study situation, we measured MVTP of 1,229 volunteers (age range : number of subjects 18-39 yr : 311, 40-59 yr : 99, 60-79 yr : 429, 80 yr and over : 390) under the permission of Hiroshima University School of Dentistry Ethical Committee. Besides MVTP measurement, subjects were inspected and interviewed about oral status and chewing/swallowing function including Repetitive Saliva Swallowing Test (RSST)For subjects w ho had no signs and symptoms of swallowing dysfunction, MVTP's mean±S.D. for each age brackets were as follows 18-39 yr : 42±11 kPa, 40-59 yr : 39±12 kPa, 60.79 yr : 32±11 kPa, 80 yr and over : 23±11 kPa. There was negative correlation between age and MV'I'P. For subjects over GO years of age, those who could swallow 3 and more times in RSST could exert stronger MVTP (29 ± 12 kPa) than those who could swallow less than 3 times could (21±12 kPa)In conclusion, based on age specific standard value acquired from the largest sample ever in this field of study, although from the limited aspect, we could diagnose some quantitative aspects of tongue function concerning swallowing function conveniently and safely
