Análise do labirinto elétrico como instrumento de avaliação de coordenação motora em crianças em idade escolar

Abstract

Introduction: The process of motor coordination gain occurs as an unique way in each child, so it is important to analyze, supervise and enrich their motor skills. Thus it is essential that motor assessments be done to identify difficulties or delays in motor development. We decided to study the use of the Buzz Wire (BW) as an instrument of evaluation in children. The BW requires dexterity to guide an aluminum ring in an iron labyrinth, trying not to touch the ring in the labyrinth. Methodology: In this study, 66 subjects aged 7 to 12 years, divided into 3 groups, according to their age group, participated. We used the MABC-2, the MABC-2, and for conducting the course in the BW, we selected rings of 8 and 6 cm in diameter and different speed controls (comfortable and faster). Three collections were made for each activity, and the best performing collection was considered for the number of errors made. Results: In the analysis of Anova Repeated Measures for the sample, with time and errors as dependent variables, and groups and tasks as independent variables, were obtained: for group F (4, 502) = 8.6155, p = 0.00 * , and for task F (6, 502) = 69,209, p = 0.00 *, both presenting significant difference. Considering a smaller sample of subjects (25), the interval correlation test with cronbach's alpha = 0.748 was performed, presenting moderate reliability. Discussion: In the analysis of the Anova Repeated Measurements of time and error data in the execution of the BW, there was a significant difference between the groups and tasks, already expected because it was 4 totally different activities. In addition, mean time was similar between groups, but G3 subjects had a standard deviation lower than G1 and G2. As it was expected the command change to tasks 3 and 4 provided an execution of the course in a shorter time, and consequently with a greater number of errors. Conclusion: We conclude that the BW is a moderate and effective reliability instrument to evaluate the motor coordination of upper limbs in children from 7 to 12 years, considering time and number of errors in performing the activity.
