Electromyographic silent periods from jaw closing muscles were elicited during a clench by tapping on the chin and on selected teeth both in asymptomatic subjects and in subjects reporting symptoms of temporomandibular joint dysfunction. The mean duration in response to a chin tap was significantly shorter in the asymptomatic group than in the dysfunction group. No significant differences in mean duration elicited by tooth taps were found between groups. Other comparisons of mean durations such as among muscles, among teeth, or between chin taps and tooth taps failed to achieve statistical significance.
在无症状受试者和报告有颞下颌关节功能障碍症状的受试者中，通过轻敲下巴和特定牙齿来引发紧咬时咬肌的肌电图静息期。无症状组对下巴轻敲的平均反应持续时间明显短于功能障碍组。两组之间由牙齿轻敲引发的平均持续时间没有显著差异。其他关于平均持续时间的比较，如不同肌肉之间、不同牙齿之间或下巴轻敲与牙齿轻敲之间的比较，均未达到统计学显著性。
