Table 1. Demographics.
Data for age, chronicity, and gait speeds are Mean ± SD. Data for LE Fugl-Meyer Synergy, Berg Balance Score, and Dynamic Gait Index are Median (Min, Max). Abbreviations: Symmetrical: paretic and nonparetic step lengths are equivalent; Pshort: paretic step length shorter than nonparetic; NPshort: nonparetic step length shorter than paretic; yr: years; m/f: male/female; r/l: right/left; mo: months; m/s: meters per second GuidanceNP: fastest comfortable walking speed, with 30% BWS, and nonparetic limb guidance; LE: lower extremity.
