title: [Electromyographic findings in children with dermatomyositis].
abstract: The author analysed electromyographic records in 14 children wit dermatomyositis. The findings included primary muscular changes of great intensity and presence of activity at rest in 50% of cases. The intensity of primary muscular changes resembled that observed in Duchenne's dystrophy and the distribution of changes was similar to that in non-progressive myopathies. Electromyographic changes occur in all cases of dermatomyositis and confirm the clinical diagnosis.
