Autopercepção corporal e o desempenho em funções motoras de crianças com Síndrome de Down

Abstract

The relation between body self-perception and movement is essential for the psychomotor structuring of the individual. It is known that children with Down Syndrome (SD) present a delay in development and a impairment in their sensorial integration that can limit some functions, such as reach and fit. The objective of this research was, therefore, to verify the association between body self-perception, performance in range and fit functions, and kinematic parameters in SD children. The research was divided into two phases, called "Evaluation of the level of self-perception and performance in the functions of reaching and fitting in children with Down syndrome when offered or not, visual feedback" (Phase 1) and " Kinematic evaluation of the level of self-perception and performance in the functions of reaching and fitting in children with Down syndrome" (Phase 2). In Phase 1, 12 children with Down Syndrome, aged between 7 and 10 years, of both sexes were evaluated. We used (1) the 'Body Notion Factor' of the 'Psychomotor Battery' and the (2) 'Performance Evaluation Protocol in the functions of reach and fit', applied in two situations: with and without visual performance feedback In real time, to the participant. The quantitative data provided by the instruments were submitted to non-parametric statistical analysis (Wilcoxon t test and Kruskal-Wallis test). A specific qualitative analysis was performed with the data provided by the 'Body Design' (item of the 'Body Notion' factor of the instrument.) In Phase 2, (2) Kinematic evaluation protocol with motion sensor system The two instruments were applied concomitantly with visual feedback through the interface of a motion sensor system presented on the screen The results of Phase 1 suggest a significant difference between body selfperception and performance in reach and fit functions with and without visual feedback. Of 6 the body indicated an influence of the visual feedback provided to the child and the characteristics of the drawings. If 2 indicate an inversely proportional relationship between body self-perception and range of motion in motor tasks and that the range of motion in motor tasks can change according to the task in children with DS.
