VARIABLES THAT MAY EXPLAIN MOTOR PERFORMANCE CHANGES IN CHILDREN WITH Development Coordination Disorder AND TYPICAL DEVELOPMENT

ABSTRACT The aim this study is investigate the relations among important factors regarding to motor development, body mass index and daily activities of children with Developmental Coordination Disorder, at risk of DCD and typically developing children before and after an motor intervention. Participants were 48 children (5 to 7 year-old) designed in intervention group (n=24) and control group (n=24) assessed using the MABC-2, MABC-2 Checklist, body mass index (BMI) and abdominal circumference. At pre test were found significant and positive correlation between motor development and BMI for all participants and for children with DCD. At the post test, for all children and for children in risk of DCD, significant and positive correlations were found between motor development and section B of check list. Intervention programs contribute to minimize the influence of risk factors in the achievement of motor proficiency of children with and without motor delays.

摘要 本研究旨在探究运动干预前后，发育性协调障碍（Developmental Coordination Disorder, DCD）患儿、DCD风险儿童与典型发育儿童的运动发育、体质指数（body mass index, BMI）及日常活动相关重要因素间的关联。本研究共纳入48名5至7岁儿童，按随机分组原则分配至干预组（n=24）与对照组（n=24），采用儿童运动协调能力评估量表第二版（MABC-2）、MABC-2检查表、体质指数（BMI）及腹围开展评估。干预前测评阶段，所有受试儿童及DCD患儿的运动发育与BMI均呈显著正相关。干预后测评阶段，所有受试儿童及DCD风险儿童的运动发育与检查表B部分均呈显著正相关。运动干预方案有助于削弱风险因素对存在运动发育迟缓与无运动发育迟缓儿童运动能力发展的负面影响。
