A specially-designed force transducer was used to measure lateral resting-tongue pressure in 23 subjects. Seventeen subjects had normal occlusion and six had dental open-bite conditions. Three sensing tips with different contact areas were used to study the relationship between sensor area and measured force. The average force of the resting tongue was 0.8 g when measured with a 4.9 mm diameter sensor (pressure = 0.039 g/mm2). When the size of the sensor tip was increased, the force of the tongue increased in a nonlinear manner. Controlled incremental lingual constrictions of 6 mm resulted in an average increase in lingual force of 230 percent. The mean rate of change, measured in deflection gradient, was 0.34 g/mm. The mean stiffness of the lingual musculature was 2.30 g/mm. A correlation of r = --0.4 was found between resting-tongue pressure and mandibular intercanine width.
使用一种特别设计的力传感器测量了23名受试者的静息舌侧压力。17名受试者咬合正常，6名受试者有牙开合情况。使用三个具有不同接触面积的传感头来研究传感器面积与测量力之间的关系。用直径4.9毫米的传感器测量时，静息舌的平均力为0.8克（压力=0.039克/平方毫米）。当传感头尺寸增大时，舌力以非线性方式增加。6毫米的受控渐进性舌收缩导致舌力平均增加230%。以偏转梯度测量的平均变化率为0.34克/毫米。舌肌组织的平均刚度为2.30克/毫米。静息舌压力与下颌尖牙间宽度之间的相关性为r = -0.4。
