Referral and diagnostic trends in pediatric electromyography in the molecular era

Abstract

EMG continues to play a cardinal role in the diagnosis of pediatric neuromuscular disorders, although its practice paradigm is evolving.

Electrophysiologic features of fibular neuropathy in childhood and adolescence

“…Most studies were performed without sedation. General features of this cohort were previously published, but did not include details of the patients with CFN . Those patients who met criteria for CFN were subjected to further data extraction and analysis for this study.…”

“…General features of this cohort were previously published, but did not include details of the patients with Abbreviations: EMG, electromyography; CFN, common fibular neuropathy; DFN, deep fibular neuropathy; EDB, extensor digitorum brevis; TA, tibialis anterior; CMAP, compound muscle action potential; SNAP, sensory nerve action potential; NCS, nerve conduction studies; SFN, superficial fibular nerve Key words: clinical neurophysiology; common fibular nerve; common fibular neuropathy; electrodiagnosis; electromyography (EMG); common peroneal neuropathy; pediatric EMG CFN. 1 Those patients who met criteria for CFN were subjected to further data extraction and analysis for this study. Clinical data collected from the EMG reports included age, gender, disease duration, symptoms, and signs.…”

“…Common fibular mononeuropathy (also known as common peroneal neuropathy) is the most common focal neuropathy of the lower extremities in all age ranges. In a series of 2100 pediatric electromyography (EMG) studies performed over 11 years, common fibular (24%) and ulnar (22%) neuropathies constituted nearly half of all diagnosed mononeuropathies . In adults, common fibular mononeuropathies rank third in frequency, behind median and ulnar mononeuropathies…”

Electrophysiologic Features of Radial Neuropathy in Childhood and Adolescence

“…Radial neuropathy is the third most common upper extremity mononeuropathy in children and adolescents (behind ulnar and median neuropathy), constituting approximately 8% of all mononeuropathies in a recent study of 2100 pediatric electromyography (EMG) evaluations performed over 11 years. 1 The clinical and electrophysiologic features of radial neuropathy have been extensively studied in adults, [2][3][4] and several comprehensive reviews have been published on this topic. [5][6][7][8] In one large series with 91 consecutive adult patients with a mean age of 44 years, the main trunk at the spiral groove of the humerus was the most frequent lesion site (47%) and traumatic injury was the most likely mechanism (70%).…”
