越来越多的证据表明，基于或有电刺激(CES)的反馈技术对闭口肌的肌电活动具有抑制作用，因此可能有助于睡眠磨牙症的治疗。这项多导睡眠图(PSG)研究旨在调查CES对自述磨牙症受试者PSG参数的影响。14名受试者按随机顺序连续三晚在实验室接受了完整的PSG检查--一晚是适应组，一晚是无CES组，一晚是CES组。在所有治疗过程中，使用便携式的颞肌反馈装置记录肌电活动。在CES治疗期间，如果检测到颌骨肌肉活动，则对受试者施加电脉冲，并将其调整为适度但不痛苦的强度。总睡眠时间、每小时微觉醒次数、处于睡眠阶段3、4和快速眼动睡眠(REM)的时间以及周期性肢体运动次数不受CES的影响。在有和没有CES的夜晚，每小时睡眠的肌电发作次数没有显著差异。目前的研究表明，在本研究中评估的任何睡眠参数中，非疼痛强度的CES都不会引起主要的唤醒反应。
There is emerging evidence that feedback techniques based on contingent electrical stimulation (CES) have an inhibitory effect on the electromyogram (EMG) activity of jaw-closing muscles and therefore could be useful in the management of sleep bruxism. This polysomnographic (PSG) study was designed to investigate the effect of CES on PSG parameters in subjects with self-reported bruxism. Fourteen subjects underwent a full PSG investigation in the laboratory for three consecutive nights - one night of adaptation, one night without CES, and one night with CES - in a randomized order. During all sessions the EMG activity was recorded by a portable feedback device from the temporalis muscle. An electrical pulse, which was adjusted to a moderate, but non-painful, intensity, was applied to subjects during the session with CES, if jaw-muscle activity was detected. The total sleep time, the number of micro-arousals per hour of sleep, the time spent in sleep stages 3 and 4 and in rapid eye movement (REM) sleep, and the number of periodic limb movements, were not influenced by CES. The number of EMG episodes per hour of sleep during the nights with and without CES was not significantly different. The present study suggests that CES at non-painful intensities does not cause major arousal responses in any of the sleep parameters assessed in this study.
