[영문]The purpose of this study was investigating the accuracy of electromyography(EMG) compared to muscle biopsy in young myopathic patients. Cases were included if the patient was 18 years and less, and the data of muscle biopsy, EMG, and final clinical diagnosis were available. EMG results were classified into 3 groups: myopathic, neurogenic, and nonspecific group. 62 patients were identified using both EMG and biopsy. EMG showed myopathic findings in 55, and microscopy revealed myopathy in 50 and nonspecific findings in 5. 28 out of 33 showed myogenic EMG findings with a conventional EMG, and the histology revealed myopathy in 24. In comparison, turns/amplitude analysis(TAA) with a conventional EMG detected myogenic findings in 27 of 29. 26 of these 27 showed myogenic findings in biopsy. We concluded that EMG is useful for the detection of myopathy in young patients. In addition, TAA may be effective when conventional EMG shows nonspecific findings.
