The purpose of the research was to study the state of autonomic regulation in prepubertal children with mitral valve prolapse during an orthostatic test Materials and methods. The study involved 2 groups: the main – 26 children aged 10-11 years with mitral valve prolapse, and a control group – 22 relatively healthy children. The adaptive mechanisms were monitored by analyzing heart rate variability. All children participated in a cardiorhythmic examination at rest lying down and during an active orthostatic test. Results and discussion. Among the indicators that had significant differences, the indicators of regulatory process adequacy index and mode amplitude should be noted. In the group of children with mitral valve prolapse, an increase of the regulatory process adequacy index indicated the predominance of the functioning of the sinus node over the activity of the sympathetic division of the autonomic nervous system. An increase in the adequacy index and mode amplitude indicates the connection of the central structures of rhythm control (subcortical rhythms) during a change in body position. Stress index also increased. This index of tension of regulatory systems shows the activity of the mechanisms of sympathetic regulation, the state of central regulation. Children in the control group had a well-coordinated response of the sympathetic nervous system to the orthostatic test: the low frequency spectrum and very low frequency indicators increased. While in main group, the value of low frequency spectrum (the work of the sinus node) increased, the value of very low frequency (the reaction of the central structures of the nervous system) decreased. This indicates dysfunction of the most important reactions, which also affects the daily activities of children, increases the risk of mitral valve prolapse complications. Conclusion. In children with mitral valve prolapse, the absence of a pronounced typical reaction to an ortho test is a reflection of an adaptive-regulatory overstrain in conditions of morphological determinacy of connective tissue dysplasia, which are trying to ensure the adequacy of intracardiac hemodynamics. The data obtained will be useful for predicting the reaction of the body of children with mitral valve prolapse to physical activity of varying intensity

The purpose of the study was to substantiate theoretically the need in high-tech rehabilitation tools for children with cerebral palsy, to identify the shortcomings of their use and to determine the role of the equipment in correcting the pathological stereotype of movement. Materials and methods. Methodological approach was used: analysis of literature sources and resources of the Internet (foreign and domestic on the PubMed and Google Scholar platforms), method of system analysis, method of comparison. Results and discussion. One of the main goals in the process of rehabilitation of children with cerebral palsy is to improve motor control and, thus, increase independence, participation and overall quality of life. In the modern world, the use of new methods of exercise therapy using high-tech robotic devices («Lokomat», «Armeo»), as well as new methods of physiotherapy, in particular, translingual electrical stimulation of the brain (TESB) «Brain-port» is becoming relevant for the treatment of children with cerebral palsy. Features and some restrictions of use of the above-stated devices were defined. Exercises on the Lokomat device help to form a motor "stereotype" of physiological walking, as well as strengthen the muscles of the lower extremities, and with the help of biological feedback to increase the motivation to exercise in children. The therapeutic goals of Armeo are to improve or maintain reach, capture and transmission movements, active range of motion by attaching an exoskeleton to the patient's arm. Translingual neurostimulation plays an important role in modulating neuroplastic changes in the brain, provides electrical stimulation of trigeminal and facial cranial nerves that modulate sensorimotor and vestibular functions. The devices help to improve the static and dynamic function of the body, reduce muscle tone, improve joint mobility in children with cerebral palsy. Their use in the process of physical therapy emphasizes the need for individualization of rehabilitation programs. Conclusion. The analysis of literature sources testifies to the effectiveness of the use of high-tech tools in the process of rehabilitation of children with cerebral palsy in combination with traditional methods. It helps to improve motor and cognitive function in children with cerebral palsy by correcting the mechanism of musculoskeletal control. Robotic techniques allow to change the pathological stereotype of movement. The prospect is to study the psychophysiological parameters of children with cerebral palsy during rehabilitation using modern technologies
