对28名有TMJ音的受试者(没有其他症状)的下颌运动进行了评估，并与28名没有TM障碍的体征或症状(包括临床上可检测到的TMJ音)的对照组进行了比较。使用与个人计算机连接的下颌运动记录仪记录下颌运动。关节的声音是用接触式麦克风记录的。用于测量下颌运动的变量在两组之间没有统计学差异，但研究组的额面平均偏移量(3.2 mm)大于对照组(2.2 mm)。所有下颌运动的组合都与关节音有关，没有明显的模式。研究对象和对照对象的差异很大，再加上在正常对象中经常发现关节音，这表明在解释电子记录的下颌运动和TMJ声音的特征时应该谨慎行事。
Mandibular movements in 28 subjects with TMJ sounds (who were otherwise asymptomatic) were evaluated and compared to those of 28 control subjects with no signs or symptoms of TM disorders (including the absence of clinically detectable TMJ sounds). Mandibular movements were recorded using the Sirognathograph interfaced with a personal computer. The joint sounds were recorded with contact microphones. The variables used to measure mandibular movements were not statistically different between the two groups except for mean mandibular deviation in the frontal plane, which was greater in the study group (3.2 mm) than the control group (2.2 mm). All combinations of mandibular movements were found to occur in relation to joint sounds with no obvious pattern. The large variability in both the study and control subjects, combined with the frequent finding of joint sounds in normal subjects, indicates that caution should be exercised in interpreting the characteristics of electronically recorded mandibular movements and TMJ sounds.
