The video-polysomnographic criteria of REM sleep behavior disorder (RBD) have not been well described. We evaluated the between-night reproducibility of phasic and tonic enhanced muscle activity during REM sleep as well as the associated behaviors and vocalizations of the patients.
Fifteen patients with clinical RBD underwent two consecutive video-polysomnographies. The amount of excessive phasic and tonic chin muscle activity during REM sleep was measured in 15 patients in 3-sec mini-epochs. The time spent with motor (minor, major, complex, and scenic) or vocal (sounds, mumblings, and comprehensible speeches) events was measured in 7 patients during REM sleep.
There was a good between-night agreement for tonic (Spearman rho = 0.55, p = 0.03; Kendall tau = 0.48, p = 0.01) but not for phasic (rho = 0.47, p = 0.1; tau = 0.31, p = 0.1) excessive chin muscle activity. On the video and audio recordings, the minor RBD behaviors tended to occur more frequently during the second night than the first, whereas the patients spoke longer during the first than the second night.
The excessive tonic activity during REM sleep is a reliable marker of RBD. It could represent the extent of dysfunction in the permissive atonia systems. In contrast, the more variable phasic activity and motor/vocal events could be more dependent on dream content (executive systems).
快速眼动睡眠行为障碍（RBD）的视频多导睡眠图标准尚未得到很好的描述。我们评估了 REM 睡眠期间相位和紧张性增强肌肉活动的夜间重现性，以及患者的相关行为和发声。
15 例临床 RBD 患者连续进行了两次视频多导睡眠描记术。在 15 例患者中，通过 3 秒迷你时程测量 REM 睡眠期间过度的颏肌相位和紧张性活动量。在 7 例 REM 睡眠期间，通过测量运动（小、大、复杂和风景）或发声（声音、嘟囔和可理解的言语）事件的时间来测量。
在 REM 睡眠期间，紧张性肌肉活动的夜间一致性较好（Spearman rho = 0.55，p = 0.03；Kendall tau = 0.48，p = 0.01），但相位肌肉活动一致性较差（rho = 0.47，p = 0.1；tau = 0.31，p = 0.1）。在视频和音频记录中，小的 RBD 行为在第二夜比第一夜更频繁地发生，而患者在第一夜比第二夜说话时间更长。
REM 睡眠期间过度的紧张性活动是 RBD 的可靠标志物。它可能代表了允许性弛缓系统功能障碍的程度。相比之下，更具变异性的相位活动和运动/发声事件可能更依赖于梦境内容（执行系统）。
