定义
入睡期脊髓性肌阵挛包括躯干、臀部和膝盖突然发生固定模式的肌阵挛抽搐，这种抽搐发生在从清醒到睡眠的过渡期间，很少发生在夜间醒来或早晨醒来时。抽搐主要发生在受脊髓神经支配的肌肉中，然后以低速传播到头-尾端肌肉，这是典型的固有脊髓通路。临床上这些运动导致明显的睡眠启动或维持困难。
Propriospinal myoclonus at sleep onset consists of sudden myoclonic jerks of the trunk, hips, and knees in a fixed pattern that occur during the transition from wakefulness to sleep and, more rarely, during nighttime awakenings or upon awakening in the morning. The jerks arise mainly in spinally innervated muscles and thereafter propagate to rostral and caudal muscles at a low speed, typical of propriospinal pathways. The movements result in clinically significant difficulty with sleep initiation or maintenance.
