It is known that EEG findings reveal various abnormalities in patients with involuntary movement. But these findings are not specific. It has been reported to be related to myoclonus and spike. The other involuntary movement is unknown to the relation to EEG findings. The involuntary movement usually disappears during sleep, but a certain involuntary movement appears only during sleep. In the patient with Huntington's chorea and dystonia musculorum deformans, PSG reveals an increase in interspersed wakefulness, decrease of deep sleep and prolongation of REM latency. Periodic limb movement and nocturnal paroxysmal dystonia appear only during sleep. Nocturnal sleep studies are important for exploring the pathophysiology in involuntary movement.
众所周知，脑电图检查结果显示不自主运动患者存在各种异常。但这些结果并不具有特异性。据报道，其与肌阵挛和棘波有关。另一种不自主运动与脑电图检查结果的关系尚不清楚。不自主运动通常在睡眠期间消失，但某些不自主运动仅在睡眠期间出现。在患有亨廷顿舞蹈病和变形性肌张力障碍的患者中，多导睡眠图显示穿插觉醒增加、深度睡眠减少以及快速眼动潜伏期延长。周期性肢体运动和夜间阵发性肌张力障碍仅在睡眠期间出现。夜间睡眠研究对于探索不自主运动的病理生理学很重要。
