Introduction: Electrodiagnostic evaluation provides an important extension to the neurological examination for the evaluation of pediatric neuromuscular disease. Many pediatric neuromuscular diseases are anologous to those seen in the adult, however, the relative frequency of these illnesses varies greatly when different age populations are compared. The purpose of the present study is to provide analysis of children referred to our electromyography (EMG)  laboratory for electrophysiological examinations.


Methods: We retrospectively reviewed electrodiagnostic records of patients aged between 0-15 years, between years January 2004 and June 2013. Patients were classified as having plexopathy, nerve root lesions, polyneuropathy, myopathy, mononeuropathy, anterior horn cell disease, neuromuscular transmission disorder, facial nerve palsy and other rare disorders.


Results: We reviewed 5563 pediatric records, which was 578 studies per year. It was about 14% of the all EMG examination perfomed in our laboratory. When we looked at the all procedures, 3271 of the records were including needle EMG, 170 of them were single fiber EMG, 100 of them were repetitive nerve stimuation, and 52 of them were evoked potentials. The results were normal in 55% of the cases. The common diagnosis were plexopathy (28.6%), polyneuropathy (7.4%), and myopathy (6.6%) in patients aged between 0-5 years (41.2% of all records). Between 6-10 years (28.2% of all records) the common diagnosis were myopathy (9.4%), PNP (8.5%), mononeuropathy (6.4%) and plexopathy (5.9%) and between 11-15 years (30.6%  of all records) the common diagnosis were PNP (11.3%), myopathy (6.6%), and mononeuropathy (5.6% ).


Conclusion: Infants and toddlers were mostly suffered from brachial plexopathy which can be prevented by proper obstetrical management. Nerve conduction studies and EMG yielded diagnostic importance for demyelinating neuropathy and myopathy in patients older than 6 years of age.
