Abstract

Research has shown that children with developmental coordination disorder rely more heavily on vision to perform movement skills than their typically developing (TD) peers. The current study purpose was to investigate the contribution of visual information during walking between TD and children at risk of having developmental coordination disorder (DCDR). Thirty-two children (age: 8.9 ± 0.9 years) were asked to walk along a 10-metre walkway at a self-selected speed under four visual conditions: full-vision, receiving vision for 150-ms and 100-ms within each 2 sec, and non-vision. The results showed that TD children walked faster and with longer steps and strides than DCDR, regardless the visual condition. Besides, the speed of walking and the step and stride length decreased significantly while the occlusion time increased, regardless the level of motor competence. The study suggests that withdrawing and limiting the visual information affect differently the gait cycle in DCDR and TD children.
