The aim of this study was to examine differences in underlying adaptations of dynamic balance in children with and without Developmental Coordination Disorder (DCD) during a Wii Fit game and to measure changes over time and after intervention. Twenty-eight children with DCD and 21 typically developing (TD) children participated in the study. Analyses of force plate variables showed that the TD group initially used a longer path length for the ski slope descent and tended toward more variation in Center of Pressure (CoP) displacement in lateral direction than the children with DCD. In contrast, the TD group showed a trend of fewer reversals per cm in both AP and lateral direction. After the nonintervention period, the TD group improved performance by decreasing the path length, while the DCD group improved by increasing the path length and by decreasing the number of reversals. After intervention, no changes were found in sway characteristics. Individual analyses within the DCD group showed that the path length per run fell more often within the 95% confidence Interval of the faultless runs. In conclusion both TD and DCD children modify the underlying kinetics of dynamic balance control, but in different ways and both lead to better performance.
本研究的目的是检验患有和未患有发育性协调障碍（DCD）的儿童在玩Wii Fit游戏期间动态平衡的潜在适应性差异，并测量随时间以及干预后的变化。28名患有DCD的儿童和21名发育正常（TD）的儿童参与了该研究。测力板变量分析表明，与患有DCD的儿童相比，TD组在滑雪道下降时最初使用的路径长度更长，并且在横向方向上压力中心（CoP）位移的变化更大。相比之下，TD组在前后方向和横向方向上每厘米的反转次数均呈减少趋势。在非干预期后，TD组通过缩短路径长度提高了表现，而DCD组则通过增加路径长度和减少反转次数提高了表现。干预后，摇摆特征未发现变化。DCD组内的个体分析表明，每次运行的路径长度更常落在无失误运行的95%置信区间内。总之，TD儿童和DCD儿童都会改变动态平衡控制的潜在动力学，但方式不同，且两者都能带来更好的表现。
