Figure 2.

Proportions of “less impaired” and “more impaired” participants in each training group who achieved a minimally important difference in walking speed. Dark gray bars represent participants classified as more strength impaired. Light gray bars represent participants classified as less strength impaired. Values represent the proportion of participants in a category whose walking speed had improved by at least 0.05 m/s after training. LR=treadmill-based training with robotic assistance, OG=overground training with electrical stimulation, TM=treadmill-based training with manual assistance, TS=treadmill-based training with electrical stimulation.
