Child’s motor development is not an isolated process but it rather involves numerous other developmental aspects, such as cognitive and conative. The research is focused on defining the developmental principles of motor abilities and skills in children with prominent motor deficits who were diagnosed with cerebral palsy (CP). The research compares the motor maturity between two groups of children with CP; the younger group (up to 10 years of age) and the older group (10 – 16 years of age). The research included 78 primary school children with different forms of CP (diplegia, hemiplegia, mixed forms), aged between 6 and 16. The discriminant analysis used in the research showed that there is a statistically significant relationship between age and motor maturity in children with CP. The structural matrix confirmed the different hierarchical representation of the motor components (strength, coordination, precision and graphomotor skills) for the selected motor model, in relation to children’s age. The function of explosive strength showed significant differences between younger and older children as regards their motor maturity. We can conclude that there is a significant developmental difference between the groups of younger and older children with CP, in relation to their motor maturity (different hierarchical representation), with the most obvious difference in motor ability of explosive strength.
