本研究比较了颅面疼痛患者 (n = 63) 或无疼痛症状 (n = 52) 以及紧张型头痛患者 (TTH: n = 30) 和健康对照个体 (n = 30) 睡眠期间的颌肌肌电图 (EMG) 活动。所有参与者都使用便携式单通道肌电图设备 (Medotech A/S) 四晚。颅面疼痛（24.5 ± 17.9 事件/小时）和无疼痛情况（19.7 ± 14.5）之间，或 TTH（20.8 ± 15.0）和健康对照个体（15.2 ± 11.6，p > 0.050）之间，肌电图活动没有显着差异。肌电图活动与疼痛肌肉数量（r = 0.188；p = 0.044）、特征疼痛强度（r = 0.187；p = 0.046）、麦吉尔疼痛问卷（r = 0.251；p = 0.008）和抑郁评分（r = 0.291；p = 0.002）之间存在正相关。与无痛个体相比，有疼痛症状的患者夜间变异性显着更高 (p < 0.050)。这项短期观察性研究表明，在睡眠期间用单通道肌电图设备记录的下颌肌肉肌电图活动方面，不同颅面疼痛状况的患者与无痛个体之间没有重大差异。然而，肌电图活动水平和颅面疼痛的各种参数之间可能存在一些关联。有必要进行纵向研究以进一步探讨睡眠磨牙症与颅面疼痛之间的关系。
This study compared the jaw-muscle electromyographic (EMG) activity during sleep in patients with craniofacial pain (n = 63) or no painful conditions (n = 52) and between patients with tension-type headache (TTH: n = 30) and healthy control individuals (n = 30). All participants used a portable single-channel EMG device (Medotech A/S) for four nights. There was no significant difference in EMG activity between craniofacial pain (24.5 ± 17.9 events/hr) and no painful conditions (19.7 ± 14.5), or between TTH (20.8 ± 15.0) and healthy control individuals (15.2 ± 11.6, p >.050). There were positive correlations between EMG activity and number of painful muscles (r = 0.188; p = 0.044), characteristic pain intensity (r = 0.187; p = 0.046), McGill Pain Questionnaire (r = 0.251; p = 0.008), and depression scores (r = 0.291; p = 0.002). Patients with painful conditions had significantly higher night-to-night variability compared with pain-free individuals (p < 0.050). This short-term observational study suggests that there are no major differences between patients with different craniofacial pain conditions and pain-free individuals in terms of jaw-muscle EMG activity recorded with a single-channel EMG device during sleep. However, some associations may exist between the level of EMG activity and various parameters of craniofacial pain. Longitudinal studies are warranted to further explore the relationship between sleep bruxism and craniofacial pain.
