肌电生物反馈(BF)训练是一种潜在的调节磨牙症的有效认知行为方法。目的采用单通道听觉EMG生物反馈(BF)仪对睡眠磨牙症患者进行昼间咬合控制。方法17例男性患者，平均年龄(24.4±63.1)岁，平均年龄(±3.10)岁，随机分为BF组(n=10)和对照组(n=10.7)。所有受试者在白天和睡眠超过3周的时间里都接受了四次肌电记录。在白天，在第二周，当受试者进行常规日常活动时，当检测到特定持续时间的过多肌电活动时，BF组收到反馈警报信号。CO组接受了肌电记录，但没有收到任何功能旁活动的警报。结果基础状态下，BF组和CO组的时相EMG事件数无显著差异，但在随访期间(第3周)，BF组的时相事件数明显少于CO组(P=0.006，Tukey‘s HSD)。由于白天BF训练的目的是为了提高对清醒磨牙症的认识，因此它不会中断睡眠顺序或涉及相关的副作用。结论本研究结果提示，针对白天强直的EMG事件的EMG BF可以有效地调节睡眠中的相性EMG事件。
BackgroundElectromyography (EMG) biofeedback (BF) training is potentially an effective cognitive‐behavioural approach to regulate bruxism.ObjectiveThis study examined sleep bruxism regulation by daytime clenching control using a single‐channel auditory EMG BF device.MethodsSeventeen male subjects (mean age, 24.4 ± 3.1 years; mean ± SD) with self‐reported awake/sleep bruxism were recruited and divided into a BF (n = 10) and a control (CO) group (n = 7). All subjects underwent four EMG recording sessions during both daytime and sleep over 3 weeks. During the daytime, in week 2, the BF group received feedback alert signals when excessive EMG activity with certain burst duration was detected while the subjects performed regular daily activities. The CO group underwent EMG recording sessions without receiving any alerts of parafunctional activity. The number of phasic burst events during sleep was compared between the BF and CO groups.ResultsWhile the number of phasic EMG events was not significantly different between the BF and CO groups at baseline, significantly smaller phasic events were observed in the BF compared to the CO group at the follow‐up session (week 3) (P= .006, Tukey's HSD). Since daytime BF training is aimed at raising awareness of awake bruxism, it does not interrupt the sleep sequence or involve associated side effects.ConclusionThe present results suggest that EMG BF targeting for tonic EMG events during the daytime can be an effective method to regulate phasic EMG events during sleep.
