目的：本研究的目的是探讨睡眠磨牙症（SB）患者咀嚼肌节律性活动（RMMA）发生的时间关系，并阐明其运动过程（平均年龄：23.4 ± 1.6岁）和10名匹配的正常对照（CTL）（平均年龄：24.4 ± 3.2岁）。RMMA和非特异性咬肌活动（NSMA）与腿部的身体运动相关。手臂，头部和躯干使用肌电图和视频记录。在睡眠阶段分布和时间关系方面，评估了睡眠发作和身体运动之间的关系。在N2阶段的orrhythmia发作前的心脏变化assessed.Results：大约80%的RMMA和NSMA与运动在一个或多个身体部位。RMMA和NSMA与腿部（70-75%）和手臂（40-55%）运动的相关性高于头部（17-22%）和躯干（5-25%）运动。在不同的睡眠阶段，睡眠发作和身体运动之间的关系没有显着差异。在SB和CTL组中，口腔运动发作和身体运动没有显示出一致的时间模式。不管癫痫发作和身体运动之间的时间关系。结论：RMMA与身体运动之间没有发现特异性的时间运动模式。RMMA和NSMA代表了睡眠期间觉醒相关的自主运动反应的一个库。
Purpose: The aims of the present study were to investigate the temporal relationships between jaw and bodily movements and clarify motor processes in the genesis of rhythmic masticatory muscle activity (RMMA) in sleep bruxism (SB).Methods: Video-polysomnography recordings were obtained from ten subjects with SB (mean age: 23.4 +/- 1.6 years) and ten matched normal controls (CTL) (mean age: 24.4 +/- 3.2 years). RMMA and nonspecific masseter activity (NSMA) were scored in association with bodily movements in the leg. arm, head, and trunk using electromyography and video recordings. The relationship between oromotor episodes and bodily movements was assessed in terms of sleep stage distributions and temporal relationships. Cardiac changes preceding oromotor episodes in stage N2 were assessed.Results: Approximately 80% of RMMA and NSMA were associated with movements in one or more body sites. RMMA and NSMA were more frequently associated with movements of the leg (70-75%) and arm (40-55%) than movements of the head (17-22%) and trunk (5-25%). The relationship between oromotor episodes and bodily movements did not significantly differ among sleep stages. Oromotor episodes and bodily movements did not show a consistent temporal pattern in the SB and CTL groups. Regardless of the temporal relationship between oromotor episodes and bodily movements. the mean heart rate significantly increased by 5 beats before the onset of oromotor episodes.Conclusions: No specific temporal motor patterns were found between RMMA and bodily movements. RMMA and NSMA represent a repertoire of arousalrelated autonomic motor responses during sleep.
