在REM睡眠行为障碍（RBD）中，一些研究集中在运动活动的肌电图表征上，而视频分析仍然更普遍。本研究的目的是进行详细和系统的视频分析。分析了5例帕金森病RBD患者的9个多导睡眠图记录，并与性别和年龄匹配的对照组进行了比较。在REM睡眠期间视频中的每个运动事件根据持续时间、运动类型和地形分布进行分类。在RBD中，识别并视觉分析了平均54 +/- 23.2次事件/10分钟REM睡眠（总计1392次）。75%的运动事件持续时间< 2秒。在这些事件中，1,155例（83.0%）被归类为基本行为，188例（13.5%）为复杂行为，50例（3.6%）为暴力行为，146例（10.5%）为发声。在对照组中，确定了3.6 +/- 1-2.3起事件/ 10分钟（共264起），主要是基本简单字符（n = 240，90.9%）。运动事件的发生次数和类型在两组间差异有统计学意义（P < 0.05）。这项研究表明，在有症状的RBD患者的REM睡眠期间，运动事件的数量非常多，种类繁多。然而，大多数运动事件都是轻微的，暴力事件只占一小部分。(c)2007年，《社会运动》创刊。
In REM sleep behavior disorder (RBD), several studies focused on electromyographic characterization of motor activity, whereas video analysis has remained more general. The aim of this study was to undertake a detailed and systematic video analysis. Nine polysomnographic records from 5 Parkinson patients with RBD were analyzed and compared with sex- and age-matched controls. Each motor event in the video during REM sleep was classified according to duration, type of movement, and topographical distribution. In RBD, a mean of 54 +/- 23.2 events/10 minutes of REM sleep (total 1392) were identified and visually analyzed. Seventy-five percent of all motor events lasted < 2 seconds. Of these events, 1,155 (83.0%) were classified as elementary, 188 (13.5%) as complex behaviors, 50 (3.6%) as violent, and 146 (10.5%) as vocalizations. In the control group, 3.6 +/- 1-2.3 events/ 10 minutes (total 264) of predominantly elementary simple character (n = 240, 90.9%) were identified. Number and types of motor events differed significantly between patients and controls (P < 0.05). This study shows a very high number and great variety of motor events during REM sleep in symptomatic RBD. However, most motor events are minor, and violent episodes represent only a small fraction.
