对9名年轻成年男性进行了吞咽过程中舌头和嘴唇对牙齿的作用力评估。放置应变计压力传感器，以便同时记录牙齿咬合时唇对上颌中切牙、舌对上颌中切牙和舌对上颌第一磨牙的情况。舌压在吞咽时，不可避免地出现在切牙和磨牙区域往往同时发生在两个区域。对于每个人来说，在吞咽过程中有一个相对一致的压力应用模式。个体之间，在压力模式和在每个区域施加的最大压力方面存在很大差异。在牙列相似的受试者中，最大唇和舌力的范围很广。用压力传感器评估异常肌肉功能可能存在解释问题。
Tongue and lip forces against the teeth during swallowing were evaluated in 9 young adult males. Strain gage pressure transducers were placed so as to allow simultaneous recording labial to the maxillary central incisors, lingual to the maxillary central incisors when the teeth were in occlusion and lingual to the maxillary first molar. Tongue pressure during swallowing which was invariably seen in incisor and molar regions tended to occur simultaneously in the 2 areas. For each individual, there was a relatively consistent pattern of pressure applications during swallowing. There were large differences between individuals, in pressure pattern and in maximum pressures exerted in each region. There is a wide range in maximum lip and tongue forces in subjects with similar denti- tions. Evaluation of abnormal muscle function with pressure transducers may present problems of interpretation.
