There is controversy over the usefulness of electromyography (EMG) in the examination of hypotonic infants with suspected neuromuscular disease. We compared the initial EMG findings of 51 such children under 1 year of age with their final clinical diagnoses determined by independent means. The EMG predicted the final diagnosis in 82% of infants less than 4 months of age and 85% of those over 4 months of age. Botulism was correctly identified by EMG in nine of 11 cases. The EMG diagnosis was identical to that obtained by muscle biopsy in 64% of cases in which biopsy was done, and diagnosis obtained by the two methods were inconsistent in only 14%. Electromyography is a sensitive and noninvasive diagnostic tool for the diagnosis of neuromuscular disease in infantile hypotonia.
对于肌电图（EMG）在疑似神经肌肉疾病的低张力婴儿检查中的作用存在争议。我们将51名1岁以下此类儿童的初始肌电图检查结果与其通过独立方法确定的最终临床诊断进行了比较。肌电图对4个月以下婴儿的最终诊断准确率为82%，对4个月以上婴儿的诊断准确率为85%。11例肉毒中毒病例中有9例通过肌电图得到正确诊断。在进行肌肉活检的病例中，64%的肌电图诊断与肌肉活检结果一致，两种方法诊断不一致的仅占14%。肌电图是诊断婴儿低张力神经肌肉疾病的一种敏感且无创的诊断工具。
