- Abstract: Propriospinal myoclonus （PSM） is a rare movement disorder. Three types of PSM have been reported：symptomatic，idiopathic and functional PSM. PSM at sleep onset is a subtype of idiopathic PSM. The current study summarized the clinical and neurophysiological characteristics of different types PSM. Methods The current study included 2 cases of PSM at sleep onset，2 cases of functional PSM，1 case of symptomatic PSM. Results Two patients with PSM at sleep onset had chronic course. Abdominal jerk was the main complaint，occurring at sleepwake transition. Mental disorders were happened in two cases with functional PSM，one of whom had various patterns of jerk and propagation. Neurophysiological examination showed that functional PSM had longer duration of muscle burst and faster velocity of recruitment. Moreover，myoclonic status was observed in PSM at sleep onset and symptomatic PSM. Conclusion PSM showed specific clinical neurophysiological characteristics according to different types. Differential diagnosis is required in clinics.
