尽管有理论推测和强烈的临床信念，最近的研究使用实验室多导睡眠图（PSG）记录提供了新的证据，睡眠磨牙症（SB）咬肌事件的频率，包括在睡眠中磨牙或咬牙，并没有增加慢性肌筋膜颞下颌关节紊乱病（TMD）的女性。目前的病例对照研究比较了一个大样本的妇女患有慢性肌筋膜TMD（n=124）与人口统计学匹配的对照组无TMD（n=46）的睡眠背景肌电图（EMG）在实验室PSG研究。背景EMG活动测量为熄灯后右咬肌的EMG均方根（RMS）。睡眠背景EMG活动定义为去除归因于SB、其他口面活动、其他口腔活动和运动伪影的活动后剩余的EMG RMS。结果表明，在这些非SB事件期间，背景EMG的中位数显著高于（P
Despite theoretical speculation and strong clinical belief, recent research using laboratory polysomnographic (PSG) recording has provided new evidence that frequency of sleep bruxism (SB) masseter muscle events, including grinding or clenching of the teeth during sleep, is not increased for women with chronic myofascial temporomandibular disorder (TMD). The current case-control study compares a large sample of women suffering from chronic myofascial TMD (n=124) with a demographically matched control group without TMD (n=46) on sleep background electromyography (EMG) during a laboratory PSG study. Background EMG activity was measured as EMG root mean square (RMS) from the right masseter muscle after lights out. Sleep background EMG activity was defined as EMG RMS remaining after activity attributable to SB, other orofacial activity, other oromotor activity and movement artefacts were removed. Results indicated that median background EMG during these non-SB event periods was significantly higher (P
