Abstract: Objective To analyze the electromyogram (EMG) changes of patients with acute flaccid paralysis (AFP) in Hetian Xinjiang.Methods Twenty-six patients with acute poliogmyelitis,admitted to our hospital from July 2011 to September 2012,were chosen in our study; their clinical data were analyzed,and they all underwent EMG examination.Results Most patients had contact with respiratory virus or digestive virus prior to illness onset.Most of patients had flaccid paralysis,muscle strength between 0 and 2 grades,tendon reflex being abated and no sensory disturbance.Fourteen patients had positive blood stool.Motor nerve conduction velocity (MCV) was abnormal,H-reflex was decreased or not educed and sensory nerve conduction velocity was normal in lower limbs of the 26 patients; EMG showed myogenic abnormality.Nerve conduction velocity was normal or low and Fwave was normal or decreased in upper limbs; EMG showed neurogenic abnormality in five of the 26 patients.Poor prognosis was concluded in all the patients.Conclusion EMG has important diagnosis value in AFP induced by polio wild-type I.
