To analyze the nature and propagation of muscle bursts in patients presenting with intensified hypnic jerks and sleep onset insomnia.
We obtained polymyographic recordings from cranially and spinally innervated muscles during polysomnographic study in 10 subjects presenting with repeated jerking movements at sleep onset, anxiety and sleep onset insomnia. One subject also had daytime polymyography during relaxed wakefulness and drowsiness as well as back-averaging of the EEG preceding the muscle bursts.
We observed 4 patterns of muscle propagation: synchronous and symmetrical patterned muscle bursts between the two sides and agonist-antagonist muscles similar to those noted in audiogenic startle reflex, reticular reflex myoclonus, dystonic myoclonus, and pyramidal myoclonus with rostrocaudal propagation of muscle bursts.
Hypnic jerks are physiological phenomena which may be accentuated and repeated and may be of several physiological subtypes.
分析伴有睡眠起始性肌阵挛和睡眠起始性失眠的患者中肌肉突发的性质和传播方式。
我们对 10 名在睡眠起始时出现反复抽搐运动、焦虑和睡眠起始性失眠的患者进行了多导睡眠图研究，获得了颅神经和脊神经支配肌肉的肌电图记录。其中 1 名患者还在放松清醒和困倦时进行了日间肌电图记录，以及在肌肉突发前对脑电图进行回溯平均处理。
我们观察到 4 种肌肉传播模式：两侧同步对称的肌肉突发模式，以及类似于听觉惊吓反射、网状反射肌阵挛、肌张力障碍性肌阵挛和金字塔式肌阵挛中所观察到的，肌肉突发呈前后向传播的作用肌和拮抗肌。
睡眠起始性肌阵挛是一种生理现象，可能会被放大和重复，并且可能有几种生理亚型。
