This Article contains errors. Figure Legends 2 and 3 were published as Figure Legends 3 and 2, the correct Figure Legends appear below: Figure 2: Group*obstacle variability for horizontal and vertical foot-obstacle distance before and after obstacle avoidance for leading and trailing limb. (a) Difference between low and high obstacle avoidance; (b) Difference between intermediate and high obstacle avoidance; (c) difference between low and intermediate obstacle. *Difference between people with PD and control group. Figure 3: Variability of kinects parameters for each group in each condition.
