Fig. 1 Measurements obtained from video over (A) high obstacles and (B) wide obstacles. Solid line represents the lead limb. Abbreviations: TCl, toe clearance, distance between lead limb toe and the obstacle's top; PrD, preobstacle distance, distance between heel of the trail limb and the obstacle's edge; PoD, postobstacle distance, distance between heel of the lead limb and the obstacle's edge; Step Length, distance between heel of the trail limb and heel of the lead limb.

Fig. 2 Notched boxplots representing toe clearance, postobstacle distance, and preobstacle distance over high and wide obstacles for subjects with stroke and healthy subjects. The notch in the boxplot represents the median; upper and lower edges of the box represent the 25th and 75th percentiles, respectively; whiskers represent the 90th percentile; dots represent the outliers. * Significant difference between stroke and healthy subjects.

Fig. 3 Notched boxplots representing step time and the proportion of step time preobstacle over high and wide obstacles for subjects with stroke and healthy subjects. The notch in the boxplot represents the median; upper and lower edges of the box represent the 25th and 75th percentiles, respectively; whiskers represent the 90th percentile; dots represent the outliers. * Significant difference between stroke and healthy subjects.
