RESUMEN
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.
