Electromyography plays a pivotal role in diagnosing neuromuscular disorders. The purpose of this study was to investigate the role of electromyography in infants. We performed a retrospective study of the infants who underwent electromyography from 2003 to 2017 and recorded demographic profile, indication, electrodiagnostic findings, and final diagnosis from the follow-up data. 179 studies were completed; electromyography was abnormal in 109 (60.9%) patients. The most common referral indication was hypotonia followed by birth trauma related injuries and rule out neuromuscular disorders. The most common electrodiagnostic diagnosis was localized to muscles followed by plexus and motor neurons. Among the patients with normal electromyography, the most common diagnosis was due to myopathies. Electromyography plays an important role in the workup of neuromuscular disorders in infants though with increased utilization of genetic testing we observed a declining trend in the number of electromyography performed in the latter half the study.
肌电图在诊断神经肌肉疾病中起着关键作用。本研究旨在探讨肌电图在婴儿中的作用。我们对 2003 年至 2017 年间接受肌电图检查的婴儿进行了回顾性研究，并从随访数据中记录了人口统计学特征、适应证、电诊断结果和最终诊断。共完成 179 项研究，109 项（60.9%）患者的肌电图异常。最常见的转诊指征是张力减退，其次是与出生创伤相关的损伤和排除神经肌肉疾病。最常见的电诊断诊断是肌肉局限性疾病，其次是神经丛和运动神经元疾病。在肌电图正常的患者中，最常见的诊断是肌病。肌电图在婴儿神经肌肉疾病的检查中起着重要作用，但随着基因检测的广泛应用，我们观察到在后一半研究中肌电图的数量呈下降趋势。
