[Electromyography in children with obstetrical paralysis].

The author for the first time conducted a EMG study of 75 children with obstetrical paralysis of the hands during the neonatal period and in children of an older age. In the majority of the cases there were certain changes of the EMG, characteristic of lesions of the spinal segmentary structures and not of the plexi as it was considered previously. During treatment directed to the area of intumescence, there was not only a clinical, but a EMG improvement as well.
