[EEG in patients with infantile cerebral palsy before and after the treatment by the method of functional biofeedback].
The paper is concerned with a study into the mechanisms of central restructures in formation of a new motor stereotype using functional biomonitoring (FBM) after different pharmacological exposures. There were 117 patients aged 5 to 14 years with spastic forms of infantile cerebral paralysis. Biomonitoring sessions were carried out with the aid of portable indicators. Pharmacological correction was performed by midocalm or galanthamine or by combining the latter one with ganglerone++. The treatment course consisted of 15 training sessions. To study the EEG structure, use was made of the method of computing conditional probabilities of one wave of the EEG, provided it was preceded by any other one. Analysis of the dynamics of the biorhythmical structure of the EEG revealed the common mechanism of restructuring the central components of movements regulation for all the patients' groups using FBM. That mechanism lay in a highly significant increase of interrelated correlations of the main components of the EEG to the alpha-component together with formation or gain of the "alpha-nucleus". The patients' group who underwent biomonitoring sessions after galanthamine and gangleron administration manifested, as compared to the other groups, a highly significant transformation of teta- and delta-components to the alpha-frequency range and enhancement of interrelation of teta-components in the "working" hemisphere. This was coupled with the most beneficial data on the patients' status.
