Motor system funkcional disorders in children with the absence of a selected phase of motor development

Abstract

The aim of this ontribution is to find out the incidence of motor sytem functional disorders in children who have missed crawling on all fours and to compare them with children who have not missed this phase. The research sample was formed by first grade elementary school pupils (n = 38) with a decimal age (6,59 ± 0,09). 19 of the probands formed a set with the missing motor development phase of crawling on all fours ( E1) and 19 did not omit this phase (E2.) We evaluated the muscle imbalance using standardised tests. There were some significant differences recorded related to m. iliopsoas and lower fixators of spatulas in muscke imbalance tests. Other muscle tests with a tendency to shorten were not statistically significant, although we found differences in favour of crawling on all four probands. Although there were significant differences in only two of the tests, in all of the muscle shortening tests, in one of the muscle weakness tests and in two of the impaired movement patterns tests, there was a higher incidence muscle imbalance of non-crawling children (NCC) on all fours compared to crawling children on all fours (CC).Acknowledgements: The contribution is a part of the grant project: ME SRS SR KEGA 020UKF-4/2021 Health, related behavior of adolescents and prevention options for diseases of civilization.
