Sleep decreases considerably the abnormal movements seen during waking in the degenerative extra-pyramidal diseases. However, the electrophysiologic recordings reveal that muscular contractions are not completely abolished. This decrease parallels the reduction of the waking system which act likely as a non-specific system of amplification. One can notice that sleep modifies the characteristics of the parkinsonian tremor and that some palatal myoclonias persist during sleep.
睡眠能显著减少锥体外系退行性疾病患者清醒时出现的异常运动。然而，电生理记录显示肌肉收缩并未完全消失。这种减少与清醒系统的减弱平行，清醒系统可能起到非特异性放大系统的作用。可以注意到，睡眠会改变帕金森震颤的特征，并且一些腭肌阵挛在睡眠期间持续存在。
