Correction system effectiveness of the children physical development of early and younger preschool age with psychomotor disorders (on the example of posture)

Purpose: to reveal the reliability of the effectiveness of the developed author's system for correcting the physical development of young and preschool children with psychomotor disorders. 
Material and methods. A total of 208 children of early (2-3 years) and younger preschool (3-4 years) age with psychomotor disorders took part in the study. Specially organized studies of the effectiveness of the system of corrective physical education for children of early and younger preschool age with psychomotor disorders were conducted during 2019 - 2021. They took place in specialized preschool education institutions, as well as kindergartens of the combined type in the city of Odesa, Odesa region, as well as in the cities of Kramatorsk, Kharkiv, Mykolaiv, Balaklia (Kharkiv region). I also summarized my own long-term (over 25 years) experience of individual rehabilitation activities with the specified contingent of children in the Odessa Movement Rehabilitation Center. All children were divided into two groups: 108 from experimental groups and 100 from control groups. 
Results. Summarizing the analysis of the results of the dynamics of physical development indicators of children with psychomotor disorders (on the example of the study of their posture), we should conclude that almost all the indicators of children from the experimental groups had a marked improvement in results, which in the absolute majority of cases was confirmed statistically (P<0,01‒0,05). Children from control groups also demonstrated some improvement of physical development indicators, but it was by no means confirmed by the methods of mathematical statistics (P>0,05). 
Conclusions: the conducted formative pedagogical experiment confirmed the reliability of the effectiveness of the developed author's system of correction of physical development of children of early and early preschool age with psychomotor disorders in comparison with the traditional system of their education.
