Relationship Between Changes in Somesthetic Evoked Responses and Electroencephalographic Findings in the Child with Hemiplegia

Abstract
The somesthetic evoked response (SER) and EEG records in 43 children with hemiplegic cerebral palsy were compared. In all children there was a positive correlation between the SER changes and the affected side of the body. In 12 children the SER of the damaged hemisphere disappeared; in 31 children it was less than the response of the healthy hemisphere. A positive correlation between the EEG changes and the affected side was found in only 16 of the patients, and there was a dubious correlation in 3 cases. SER data are apparently more accurate and reliable than EEG results. SER findings allowed cerebral damage to be suspected earlier than the EEG results and are of greater prognostic value.
