Abstract

Background: Previous research suggests that children with or at risk of probable developmental coordination disorder (pDCD) activate different areas of the brain when performing certain motor skills compared with typically developing (TD) children. This study used functional near-infrared spectroscopy to compare prefrontal cortex (PFC) activity in TD and pDCD during the completion of manual (three-dimensional [3D]) and computerized versions (two-dimensional) of the Tower of Hanoi (ToH) puzzle. Method: A total of 12 children (TD and pDCD; one female/11 male, , SD ± 1.52 years) performed the two-dimensional and 3D conditions of the ToH disk tasks, with equivalent executive function but different motor requirements, with functional near-infrared spectroscopy to compare PFC activity. Results: Interestingly, brain oxygenation levels were more apparent in the 3D versus two-dimensional ToH. In the 3D, there were large differences between pairs of discordant sibling sets and this was located to the right medial PFC, with pDCD exhibiting less activation in this region. Conclusion: While only exploratory, we have identified potential differences in the right medial PFC region, which differs within sibling sets with different pDCD status. These results concur with previous studies and are an area that needs to be explored further with a larger cohort of TD and pDCD.

有或没有发育性协调障碍的兄弟姐妹的前额叶皮层活动:一项探索性研究

背景:先前的研究表明，与正常发育(TD)儿童相比，患有或有可能患有发育协调障碍(pDCD)的儿童在执行某些运动技能时激活的大脑区域不同。本研究使用功能性近红外光谱比较了在完成手工(三维[3D])和计算机版本(二维)的河内塔(ToH)拼图时，TD和pDCD的前额叶皮质(PFC)活动。方法:共12例患儿(TD和pDCD;1名女性/11名男性，SD±1.52岁)执行二维和三维条件下的ToH磁盘任务，执行功能相同，但运动要求不同，用功能近红外光谱比较PFC活动。结果:有趣的是，脑氧合水平在3D比二维ToH更明显。在3D中，不一致的兄弟姐妹组之间存在很大差异，这位于右侧内侧PFC, pDCD在该区域表现出较少的激活。结论:虽然只是探索性的，但我们已经确定了右侧内侧PFC区域的潜在差异，不同pDCD状态的兄弟姐妹之间存在差异。这些结果与先前的研究结果一致，这是一个需要在更大的TD和pDCD队列中进一步探索的领域。

期刊介绍： The Journal of Motor Learning and Development (JMLD) publishes peer-reviewed research that advances the understanding of movement skill acquisition and expression across the lifespan. JMLD aims to provide a platform for theoretical, translational, applied, and innovative research related to factors that influence the learning or re-learning of skills in individuals with various movement-relevant abilities and disabilities.
