Abstract: Propriospinal myoclonus(PSM)is a rare painless movement disorder characterized by recurrent axial myoclonus during the wake and sleep transition periods.The recurrent muscle twitches during the hypnotic period severely affect the patient's sleep.In this paper,we reported a case of typical PSM.The patient was treated for involuntary limb shaking before sleep for more than 1 year,and no significant positive signs were found after physical examination in hospital.After perfecting video polysomnography and polymyography,he was diagnosed as having idiopathic PSM,and he responded well to 1/3 of clonazepam tablets,suggesting the necessity of video polysomnography and polymyography in the diagnosis of PSM.
