Age features of the functional state of the vestibular sensory system in the pupils of the middle classes with the visual impairments

Abstract

Disclosed the role of the functional state of the vestibular sensory system in the development of the children with the visual impairments. It was found that the vestibular analyzer is important in the management of the motor activity, development of the motor qualities, formation of the motor skills and abilities.
 Considered the indicators of the functional state of the vestibular sensory system in the pupils of the middle grades with the visual impairments, which were determined and evaluated according to the results of the stability of the vestibular analyzer before and after rotational loads in the Barani chair. The study was conducted on the basis of the municipal institution «Kharkiv special boarding school I–III degrees № 12». It was attended by 117 visually impaired pupils of 5th–10th grades, aged 10–16 years. To achieve the goal of the study, the following methods were used: theoretical analysis and generalization of scientific and methodological literature, physiological methods for the determining the resistance of the vestibular analyzer to rotational loads, methods of the mathematical statistics. A comparison of the results of the stability of the vestibular analyzer before and after rotational loads in the Barani chair in boys and girls of the middle school age with the visual impairments depending on age is presented. It is determined that the resistance of the vestibular analyzer to rotational loads in the Barani chair in the visually impaired pupils of the middle grades improve with age; after rotational loads – in boys they improve, in girls they change in waves.
 It is established that the best indicators of the stability of the vestibular analyzer before and after the rotational loads in the Barani chair observed in the pupils of the 10th grade, aged 15–16 years.
