Figure 2. — Step length. (A) Paretic- and nonparetic-limb step length averaged across all participants (N=20). P=paretic leg, NP=nonparetic leg. (B) Step length asymmetry results across all speeds for all participants with step length asymmetry (n=14). (C) Step length asymmetry results across all speeds for participants with a longer paretic-leg step (n=7) at free speed. (D) Step length asymmetry results across all speeds for participants with a shorter paretic step (n=7) at free speed. FR1 and FR2 were intermediate speeds between free and fast speeds. Asterisk indicates significant difference among speeds. “Abs” refers to absolute value of the quantity in the parentheses.
