This study examined the ability of children with hemiplegia to perform motor imagery of their unaffected hand. Children (8-12 years) formed three groups--R-HEMI: right-sided hemiplegia, n = 21; L-HEMI: left-sided hemiplegia, n = 19; and Comparisons, n = 21. We expected no group differences on a simple imagined grasping task, but the hemiplegia groups to perform atypically on an imagined pointing task. Results showed no group differences on the grasping task, while only the L-HEMI group performed atypically on the pointing task-- the functional level of the children played a likely role in this finding. Children with hemiplegia can engage in motor imagery, although task complexity and functional level may have an impact.
本研究考察了偏瘫儿童对其未受影响的手进行运动想象的能力。儿童（8至12岁）分为三组——右偏瘫组（R-HEMI）：右侧偏瘫，n = 21；左偏瘫组（L-HEMI）：左侧偏瘫，n = 19；以及对照组，n = 21。我们预计在简单的想象抓握任务上各组之间没有差异，但偏瘫组在想象指向任务上的表现会异常。结果显示在抓握任务上各组之间没有差异，而只有左偏瘫组在指向任务上表现异常——儿童的功能水平可能在这一结果中起到了作用。偏瘫儿童能够进行运动想象，尽管任务复杂性和功能水平可能会产生影响。
