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

本研究的目的是建立一种基于年龄特异性最大自愿舌压标准值（MVTP）的新型简便舌功能诊断方法。我们在广岛大学牙科学院伦理委员会的许可下，装配了一次性口腔内探针和便携式装置的实用系统，使我们能够在诸如流行病学研究情况等多种环境中测量舌压，我们测量了1229名志愿者（年龄范围：18-39岁：311,40-59岁：99,60-79岁：429,80岁及以上：390）的MVTP。除测量MVTP外，还对被试进行口腔状况和咀嚼/吞咽功能的检查和访谈，包括重复性唾液吞咽试验（RSST）。对于没有吞咽功能障碍体征和症状的被试，MVTP均值±sd18-39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MV'I'P呈负相关。在年龄超过60岁的受试者中，吞咽3次及以上的受试者比吞咽3次以下的受试者（21±12 kPa）能产生更强的MVTP（29±12 kPa）。综上所述，基于本研究领域迄今为止最大样本的年龄特定标准值，虽然从有限的角度来看，我们可以方便、安全地诊断出吞咽功能方面的舌头功能的一些定量方面

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
