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

Figure 2

Boxplots of cognitive-motor interference scores for the plain walking environment and the two challenging walking environments with either stationary physical context (challenging-physical) or suddenly appearing projector-augmented context (challenging-projected). Negative values indicate poorer dual-task than single-task performance (i.e., cognitive-motor interference). One extreme outlier (223% in challenging-projected) was omitted from the figure. Significant effects () are represented by solid lines and tendencies () are represented by dashed lines.
