We used elliptical Fourier analysis (EFA) to examine potential differences in the complexity and variability of gait of children with (N=10) and without (N=10) Developmental Coordination Disorder (DCD). Children with DCD generated movement patters with larger variability and complexity than typically developing (TD) children. In addition, children with DCD exhibited greater asymmetry in their movement patterns compared to TD children. Our results suggest that children with DCD have significantly greater difficulty producing consistent movement patterns both across their left and right legs and over repeated strides. EFA techniques show promise for distinguishing between different groups of individuals.

我们使用椭圆傅立叶分析 (EFA) 来检查有 (N = 10) 和没有 (N = 10) 发育协调障碍 (DCD) 的儿童步态复杂性和变异性的潜在差异。与典型的发育 (TD) 儿童相比,患有DCD的儿童产生的运动模式具有更大的变异性和复杂性。此外,与TD儿童相比,DCD儿童的运动方式表现出更大的不对称性。我们的结果表明,患有DCD的儿童在左腿和右腿以及反复跨步时产生一致的运动模式的难度明显更大。全民教育技术显示出区分不同群体的希望。
