外骨骼增强步态策略的个体差异可能源于认知因素的差异，例如，对刺激的快速反应能力或在分散注意力下完成任务的能力。步态策略被定义为实现步态优先级的不同方法（例如，行走不摔倒），并通过标准化步幅或宽度等步态特征的变化来观察。变化表明优先级的变化，比如增加稳定性或与外骨骼的协调性。评估认知因素与外骨骼步态特征之间的关系。认知因素通过一个改进的Simon任务和一个在自定节奏跑步机上的速度成就任务来量化，有或没有第二个去/不去的任务。反应时间较快、维持既定速度能力下降的个体往往优先考虑外骨骼的协调性，而不是步态稳定性。这些相关性表明认知因素与个体外骨骼增强步态策略之间的关系，应该进一步研究以了解外骨骼使用的变化。
Individual variation in exoskeleton-augmented gait strategy may arise from differences in cognitive factors, e.g., ability to respond quickly to stimuli or complete tasks under divided attention. Gait strategy is defined as different approaches to achieving gait priorities (e.g., walking without falling) and is observed via changes in gait characteristics like normalized stride length or width. Changes indicate shifting priorities like increasing stability or coordination with an exoskeleton. Relationships between cognitive factors and exoskeleton gait characteristics were assessed. Cognitive factors were quantified using a modified Simon task and a speed achievement task on a self-paced treadmill with and without a secondary go/no-go task. Individuals with faster reaction times and decreased ability to maintain a given speed tended to prioritize coordination with an exoskeleton over gait stability. These correlations indicate relationships between cognitive factors and individual exoskeleton-augmented gait strategy that should be further investigated to understand variation in exoskeleton use.
