Abstract:
Objective To explore the feature of electrical physiology and the key aspect of diagnosis in early stage of spinal muscular atrophy in infants.Method The back clinical data of the musle change of electrical physiology within 25 cases were analyzed.Results The children were ill in 1 year old,with the symptom that four limbs present symmetry and paralysing slowly,low limbs being more serious than upper limbs,the close and the distant of the four limbs.The levels of creatine kinase(CK) and lactate dehydrogenase(LDH) in serum were normal and the case unconcentrated was not seen rarely.The show of electromyogram(EMG) was that three limbs presenting wide-range losing nerve electric potential in peace state,when straingently the deadline was long and the motor unit potential(MUP) was high,when strain highly the eletric potential was decreased;the speed of nerve conduction was common.Muscle inspection was typical nervine myatrophy.Conclusion The clinical feature,the changes of muscle electrical physiology and the muscle inspection are valuable for diagnosis so as to afford reliable evidence for further gene diagnosis.J Appl Clin Pediatr,2006,21(3):167
