Lower-extremity Independence Levels during Standing. (A) Percent of total Standing time across all sessions with left knee (gray), right knee (blue) or bilateral (pink) independence. Each line is a participant during their initial standing intervention (80 sessions). (B) Percent of total Standing time across all sessions with left knee (gray), right knee (blue) or bilateral (pink) independence. Each line is a participant during their second standing intervention (Groups 3 and 4). (C) EMG features in time and frequency domains collected during standing pre and post intervention. EMG features values were averaged among participants and among all assessed muscles. Values are expressed as median + mean absolute deviation. Differences were tested by Wilcoxon test * p < 0.05. (D) EMG features in time and frequency domains collected during standing post intervention 1 and post intervention 2 for groups 3 and 4. EMG features values were averaged among participants and among all assessed muscles. Values are expressed as median + mean absolute deviation. (E) Color map (top) shows the bilateral independence time during each training session (rows) across participants (columns) for the two-hour intervention during their initial standing intervention (80 sessions). Top row indicates the first session. Box plot (bottom) representing bilateral independence time for each participant. Median is represented in red. (F) Color map (top) shows the bilateral independence time during each training session (rows) across participants (columns) for the two-hour intervention during their second standing intervention (Groups 3 and 4). Top row indicates the first session of the second standing intervention. Box plot (bottom) representing bilateral independence time for each participant. Median is represented in red
