Curve figures of the distance between feet. The wave crests represent the SL of each step. (A) Three types of kinematic features from the subjects. (B) and (C) Characteristic trajectories of the serious, moderate, and mild conditions in the stroke and PD group. (D) The most serious patient in the stroke group; the wave crests of the affected side (indicated by the red arrow) are significantly lower than those of the normal side. (E) A moderate patient in the stroke group; the difference between the affected and normal sides is less than in the most serious stroke patient (D)
