目的：在进食和说话过程中，舌的运动与颌骨和舌骨的运动是时空协调的。因此，我们评估了：(1)进食和说话时舌骨和舌骨运动的相关性，以及(2)颌骨和舌骨对舌骨运动的相对影响。设计：在16名健康受试者吃固体食物或阅读标准段落的情况下，记录侧向投影视频透视。以上尖牙为笛卡尔坐标的原点(0，0)，量化舌标(ATM和PTM)、颌骨和舌骨相对于上(牙合)平面的位置。结果：在垂直方向上，ATM和PTM位置与进食时的颌骨和舌骨高度相关(中位数r=0.87)。对于atm位，颌骨的相对影响大于舌骨(P<；0.001)，而对PTM位的相对影响较小(P=0.04)。在水平方向上，舌标位置与进食时的颌骨和舌骨有中等程度的相关性(r=0.47)，更多的是由于舌骨位置而不是颌骨位置。总体而言，在说话过程中的相关性低于在饮食过程中的相关性。结论：本研究证实了颌骨、舌骨的运动与舌前部和舌后部标记之间存在明显的运动学联系，以及颌骨和舌骨在决定饮食和言语过程中舌头运动的不同影响。(C)2010爱思唯尔有限公司。保留所有权利。
Objective: Tongue movement is temporo-spatially coordinated with jaw and hyoid movements during eating and speech. As such, we evaluated: (1) the correlation between the tongue with jaw and hyoid movements during eating and speech and (2) the relative influence of the jaw and hyoid on determining tongue movement.Design: Lateral projection videofluorography was recorded while 16 healthy subjects ate solid foods or read a standard passage. The position of anterior and posterior tongue markers (ATM and PTM, respectively), the jaw, and the hyoid relative to the upper occlusal plane was quantified with the upper canine as the origin (0,0) point for Cartesian coordinates. For vertical and horizontal dimensions, separate multiple linear regression analyses were performed with ATM or PTM position as a function of jaw and hyoid positions.Results: Vertically, both ATM and PTM positions were highly correlated with the jaw and hyoid during eating (median r = 0.87). The relative influence was higher for the jaw than the hyoid for ATM position (P < 0.001), but lower for PTM position (P = 0.04). Horizontally, tongue marker positions had moderate correlation with the jaw and hyoid during eating (r = 0.47), due more to hyoid position than to jaw position. Overall, correlations were lower during speech than eating.Conclusion: This study demonstrated distinct kinematic linkages between the movements of the jaw, the hyoid and the anterior and posterior tongue markers, as well as differing impact of the jaw and the hyoid in determining tongue movement during eating and speech.
