比较典型发育（TD）儿童和偏瘫脑瘫（HCP）儿童在单任务和双任务条件下的前额皮质（PFC）激活和任务表现。前瞻性的比较设计。研究实验室。参与者 (N=21) 包括 12 名 TD 儿童（年龄，6.0±1.1 岁）和 9 名 HCP 儿童（年龄，7.2±3.1 岁）。不适用。通过测量氧合血红蛋白的浓度来评估 PFC 的激活情况，同时孩子们坐在稳定的表面（单一任务）与动态表面（双重任务）上用受影响较大的手臂执行形状匹配任务。任务绩效通过匹配的形状总数、双任务成本和反应时间（RT）来评估。对于这两种情况，患有 HCP 的儿童比 TD 儿童表现出更大的 PFC 激活、匹配的形状更少、RT 更慢。这些差异在双任务条件下更加突出，并且双任务成本更大。在 HCP 儿童中，双任务条件下 PFC 激活的增加与较高的双任务成本密切相关 (r=0.77，P=.01)。患有 HCP 的儿童在执行双重任务时似乎有大量的 PFC 活动。更大的皮层活动可能是任务的运动和认知需求之间共享的有限注意力资源的结果。患有 HCP 的儿童的认知运动干扰可能会加剧，因为发育中的大脑受到损害，导致大脑结构和功能发生变化。
To compare the prefrontal cortex (PFC) activation and task performance during single- and dual-task conditions between typically developing (TD) children and children with hemiplegic cerebral palsy (HCP). A prospective, comparative design. Research laboratory. Participants (N=21) included 12 TD children (age, 6.0±1.1y) and 9 children with HCP (age, 7.2±3.1). Not applicable. PFC activation was assessed by measuring the concentration of oxygenated hemoglobin while the children performed a shape-matching task with their more affected arm while sitting on a stable (single task) vs dynamic surface (dual task). The task performance was assessed with the total number of shapes matched, dual-task cost, and reaction time (RT). For both conditions, the children with HCP exhibited greater PFC activation, matched a fewer shapes, and had slower RT than the TD children. These differences were accentuated during the dual-task condition and the dual-task cost was greater. An increase in the PFC activation during the dual-task condition was tightly correlated with a higher dual-task cost in children with HCP (r=0.77, P=.01). Children with HCP appear to have a heightened amount of PFC activity while performing a dual task. The greater cortical activity may be a result of the finite attentional resources that are shared between both the motor as well as cognitive demands of the task. The cognitive-motor interference is likely exacerbated in children with HCP because of the structural and functional brain changes as a result of an insult to the developing brain.
