Correlação entre coordenação motora e desempenho funcional em atividades com bola em crianças com e sem Transtorno do Desenvolvimento da Coordenação

Abstract

Introduction: Developmental Coordination Disorder (DCD) is a condition difficult to diagnose that interferes with the performance of daily activities requiring motor coordination skills. Several tests are used in research and clinical practice to evaluate the motor components related to difficulties experienced by these children. However, their results are not sufficient to predict the functional performance of daily life of children with DCD. Objective: To investigate the relationship between motor components, particularly bilateral motor coordination and balance, and functional performance in the area of activities with the ball. Methods: Secondary analysis of the database project in progress, with a sample of 27 children (seven and eight years of age) identified with DCD and their peers without motor problems. We examined the relationship between the test results Movement Assessment Battery for Children - MABC-2 and the observations of parents and teachers about the child's motor skills at home and at school, through Developmental Coordination Disorder Questionnaire (DCDQ-Brazil) and questionnaires from parents and teachers of the Assessment Coordination and Motor Skills (ACOORDEM). Results: Mann Whitney test indicated that children with DCD had significantly lower results than the typical children of the same age in all evaluated items. The Spearman coefficient indicated significant associations between the variables representing sensorimotor components (motor coordination and balance) and the variables of functional performance, but low to moderate magnitude. Discussion: The results of this study are in line with previous research highlighting the poor motor performance of children with DCD. The magnitude of the association shows that, for carrying out activities with balls, sensorimotor components are important and influence the functional performance, as noted by the parents. However, the results do not fully explain the function of the child and suggest the existence of other factors that may influence performance in everyday activities with balls. Conclusion: It is essential that professionals working with children with DCD broaden his view of the functional performance, in addition to sensorimotor deficits, and start to analyze the motor disorder in different focus Parents and teachers play a fundamental role in the therapeutic process, to contribute with information about the activity and participation of children, helping the decision-making in treatment. Future studies should investigate other variables such as the environmental context and motivation of the child, which may facilitate or restrict the individual's functional performance.
