ELECTROPHYSIOLOGICAL SUPPORT IN CHILDREN STATUS EVALUATION WITH SPEECH DISORDERS

Speech is one of the most complex higher mental functions. Practically none of the forms of higher nervous activity is formed and implemented without direct or indirect involvement of speech. Currently, speech dysfunctions in children frequently occur, and the mechanisms of their origin have been insufficient studied. All above-mentioned reasons indicate the needs for evaluation of children’s’ status with speech disorders by complex electrophysiological examination to contribute to appropriate corrective measures aimed at speech restoration.

Electroencephalograph EEGA-21/26 "Encephalan-131-03" allows registering various physiological signals including EEG by means of four polygraph channels. The study design might contain electroencephalography in various modifications: electromyography, in particular, the orbicular muscle of mouth (involved in sounds pronunciation, available for study); pneumography (emphasis on respiration frequency and amplitude) as the second polygraph channel; and I routine electrocardiography as the fourth polygraph channel.

The study is conducted in a sitting position, at rest, and in mental activity state involving speech apparatus (repeating simple quatrains loudly and in whisper). The results are undergone the visual and automated processing.
Revealed features of bioelectric brain activity, speech muscles, and vegetative functions at rest and during mental activity involving speech apparatus help to reveal the mechanisms of speech disorders in children.

Thus, electrophysiological support in children status evaluation with speech disorders is reasonable for disorders genesis clarification and for further selection of drug and non-drug corrective measures to stimulate normal speech formation and other higher mental functions of the brain.
