PSM at sleep onset is a subtype of PSM that occurs during the sleep–awake transition and causes severe sleep-onset insomnia.1 Previous case reports have focused on the etiology and mechanism of PSM, but have not evaluated tre...
متن کاملPropriospinal myoclonus: report of a case.
Propriospinal myoclonus is an unusual movement disorder. Here we reported a patient with electrophysiological data. The 32-year-old man had spontaneous, intermittent and brief jerks over the trunk, hip and lower limbs muscles for 4 years. The jerks were not sensitive to external stimuli and usually exacerbated whenever the patient felt relaxed, particularly preceding the onset of sleep. Electro...
