Dual-Task Walking in Challenging Environments in People with Stroke: Cognitive-Motor Interference and Task Prioritization

Figure 1

Schematic representations of the three walking environments. (a) Plain walking environment. (b) Challenging walking environment with stationary physical context (challenging-physical; comprising three stepping targets, a 2-m tandem-walking path, and three obstacles). (c) Challenging walking environment with suddenly appearing projector-augmented context (challenging-projected; comprising position-dependent and gait-dependent obstacles).
