Secondary outcome measures on a subset of participants (n = 8).

Outcome measure	Description
Step length	The average step length for each gait cycle was computed as the forward linear displacement between foot contact of the ipsilateral leg to foot contact of the contralateral leg during each gait cycle.
Temporal measures	Total time was computed as the time between foot contact of one leg to the subsequent foot contact of the same leg. The average total time was computed for each gait cycle. Further, average swing time for each subject during each condition was computed as the time between the foot off the floor of one leg to foot contact of the same leg during the gait cycle. The stance time was computed as time between foot contact of one leg to foot off of the same leg.
Temporal-spatial symmetry (Holden et al., 1984)	The swing and stance time of each foot during each gait cycle was computed, and the following ratios were used to compute the temporal asymmetry: $$\begin{array}{r}Temporalswingstancesymmetry=(swingtime)/(stancetime)\end{array}$$ (1) Equation (2) was computed for both affected and unaffected limbs $$\begin{array}{r}Overalltemporalsymmetry=(\frac{affectedswingstancesymmetry}{unaffectedswingstancesymmetry})\end{array}$$ (2) The step length of each foot was computed for each gait cycle, and the spatial symmetry ratio was calculated as follows: $$\begin{array}{r}Spatialsymmetry=(\frac{unaffectedsteplength}{affectedsteplength})\end{array}$$ (3)
