A variety of spontaneous movements can occur during sleep. Most are unassociated with identifiable CNS pathology and are presumed to be caused by sleep-related modulation of CNS motor control systems. Individual dyskinesias occurring during sleep can be characterized not only by their frequency, rhythmicity, and anatomic predilections, but also by the stage of sleep in which they characteristically occur. Wake-pattern movement disorders improve during sleep but, contrary to common belief, they do not entirely disappear. Instead, these disorders reemerge in attenuated form, often during nonrapid eye movement sleep. The identification and proper characterization of the various sleep-related dyskinesias are greatly aided by careful polysomnographic study.
睡眠期间可出现多种自发运动。大多数与可识别的中枢神经系统病变无关，推测是由中枢神经系统运动控制系统的睡眠相关调节引起的。睡眠期间出现的个体运动障碍不仅可以根据其频率、节律和解剖学偏好来表征，还可以根据其典型出现的睡眠阶段来表征。觉醒模式的运动障碍在睡眠期间会改善，但与普遍看法相反，它们并不会完全消失。相反，这些障碍会以减弱的形式再次出现，通常在非快速眼动睡眠期间。仔细的多导睡眠图研究极大地有助于识别和正确表征各种与睡眠相关的运动障碍。
