Abstract: The relevance of the study is determined by the increasing number of younger schoolchildren with difficulties in mastering reading and writing. In recent decades, the hypothesis has been confirmed that one of the causes of difficulties in mastering reading and writing in elementary school may be reduced sensory reactivity of the vestibular system. The article presents the results of an experimental study of dynamic visual acuity in children with learning difficulties. Dynamic visual acuity reflects the quality of interaction between the visual and vestibular systems. Its violations can complicate the development of reading and writing.
The study involved 35 primary school students with learning difficulties. The study was conducted on the basis of a pediatric neurological clinic, instrumental studies and vestibular training were conducted as prescribed by a neurologist. At the first stage, functional diagnostics of vestibular function was carried out. The functions of the otolith part of the vestibular apparatus were evaluated by the method of cervical vestibular evoked potentials. The functions of the horizontal semicircular channels of the vestibular apparatus were evaluated by measuring the duration of post-rotational nystagmus. The experimental group included children whose learning difficulties were combined with sensory hyperactivity of the vestibular system or asymmetry of sensory reactivity of the vestibular system.
Then the children underwent vestibular training on a riding simulator with visual biofeedback. The duration of the training is 14 days. The assessment of dynamic visual acuity was carried out by the standard method in sitting and standing positions before and after the training.
Dynamic visual acuity depends on the quality of the vestibulocular reflex. It is shown that vestibular training on a riding simulator with visual biofeedback significantly improves dynamic visual acuity in a group of children with hyperactivity, symptoms of astheno-neurotic syndrome, asymmetry of sensory reactivity of the vestibular apparatus. Further research is needed to assess the impact of the training results on the success of children in learning.

Abstract: The results of an experimental study aimed at assessing the dynamics of electroencephalographic parameters of children with epilepsy and/or epileptic changes and concomitant developmental disorders during audio training using the A. Tomatis method are presented. The study involved 820 children aged 2.5 to 6.5 years with autism spectrum disorder and severe language development disorders. The audio training was part of a fifteen-day rehabilitation course, which was conducted according to the appointment of a neurologist. The trainings were aimed at modulating the work of the auditory and vestibular systems in order to normalize the ability to learn and improve the quality of life. For the first time, the effectiveness and safety of audio training using the Tomatis method was evaluated for children with epilepsy and/or epileptic changes and concomitant developmental disorders. This is the first study of the effectiveness of the Alfred Tomatis method, conducted on a large sample with the control of electroencephalographic parameters. Encephalographic indicators were recorded during the use of frequency filters, as well as before and after the training.
For the first time, encephalographic indicators were monitored using portable equipment directly while listening to music.
It was found that 80.3% of the subjects had stable EEG indicators before, during and after audio training using the A.Tomatis method. 8.2% of children had a tendency to deterioration of EEG indicators. 11.5% of children had a decrease in the index of representation of epileptiform changes. Audio training by the method of A.Tomatis does not significantly aggravate the electroencephalographic picture in most children and can be used in rehabilitation in children with epileptiform disorders and epilepsy under the supervision of an epileptologist and after a preliminary functional diagnosis. Taking into account the capabilities of modern electroencephalographs, for greater safety of children with concomitant epileptiform disorders, it is recommended to conduct audio training using the A.Tomatis method under EEG control.
