Walking function. Walking independence was achieved with the use of a reverse rolling walker at baseline (A, top panel). Walking independence remained relatively unchanged at 1 year after locomotor training (LT) (A, bottom panel) and 2 years after LT (Walking Index for Spinal Cord Injury–Version II [WISCI-II] scores; B). Fastest gait speed (dashed line) continued to increase over time, despite no changes in the WISCI-II score (B). The number of steps taken across the 24-hour period increased substantially from baseline to 1 year after LT and was sustained at 2 years after LT (C). This trend also was evident in the number of steps averaged from 2 days (D, black bar graphs) and the corresponding average number of total stepping bouts (D, dashed line). Error bars denote standard deviation.
