在行走模式之间切换的能力（即，运动转换）对于成功的社区导航至关重要，并且可能受到中风后损伤的影响。因此，这项工作的目的是研究运动转换和运动转换和流体认知之间的关系，在中风后的个人相比，神经典型的成年人。29名中风后> 6个月的个体和18名神经典型的成年人参加了为期两天的研究。在第1天，参与者在跑步机上学习一种新的步行模式，然后通过指导参与者在新的步行模式和他们通常的步行模式之间切换来评估运动切换。这两种模式之间的变化被计算为转换指数。在第2天，施用NIH认知测验-认知测验以获得反映流体认知的流体认知综合评分（FCCS）。使用ANCOVA比较各组之间的转换指数，并使用回归评估运动转换和流体认知之间的关系。中风后个体的转换指数显著低于神经型成人（p=0.03）。回归显示，群体与FCCS之间存在显着的相互作用（p=0.002），FCCS可以预测神经典型成年人的转换指数，但不能预测中风后个体的转换指数。中风后的个体似乎有缺陷的运动转换相比，神经典型的成年人。流体认知和运动转换之间的关系在神经典型的成年人中是显着的，但在中风后的个体中没有显着性。未来的工作，以了解特定的认知领域和运动转换之间的关系是必要的（见视频，补充数字内容1）。
The ability to switch between walking patterns (i.e., locomotor switching) is vital for successful community navigation and may be impacted by post-stroke impairments. Thus, the purpose of this work was to examine locomotor switching and the relationship between locomotor switching and fluid cognition in individuals after stroke compared to neurotypical adults. Twenty-nine individuals > 6-months post stroke and eighteen neurotypical adults participated in a two-day study. On day 1, participants were taught a new walking pattern on the treadmill and then locomotor switching was assessed by instructing participants to switch between the new walking pattern and their usual walking pattern. The change between these two patterns was calculated as the Switching Index. On day 2, the NIH Toolbox -Cognition Battery® was administered to obtain the Fluid Cognition Composite Score (FCCS), which reflected fluid cognition. Switching Index was compared between groups using an ANCOVA and the relationship between locomotor switching and fluid cognition was assessed with regression. Individuals after stroke had significantly lower Switching Indexes compared to neurotypical adults (p=0.03). The regression showed a significant interaction between group and FCCS (p=0.002), with FCCS predicting Switching Index in neurotypical adults but not in individuals after stroke. Individuals after stroke appear to have deficits in locomotor switching compared to neurotypical adults. The relationship between fluid cognition and locomotor switching was significant in neurotypical adults but not in individuals after stroke. Future work to understand the relationship between specific cognitive domains and locomotor switching is needed (See Video, Supplemental Digital Content 1).
