To compare immediate effects of stepping training with or without the utility of external feedback on functional ability relating to walking in ambulatory patients with iSCI (between-group comparison).~Secondary objective To compare immediate effects in a group of stepping training with or without the utility of external feedback on functional ability relating to walking in ambulatory patients with iSCI (within-group comparison).
Does stepping training with or without external feedback change functional ability of ambulatory patients with iSCI immediately after training?~Are there significant differences between the immediate effects of stepping training with or without external feedback in ambulatory patients with iSCI?
