Changes in supported fraction of range and fraction of speed. Values are shown for the three preliminary evaluations (weeks 1, 2, and 3), three post-therapy evaluations (weeks 12, 13, and 14), and at the 6-month follow-up evaluation. Plots A and B (left column) show the improved FRS and FSS after the training period and sustained values at follow-up for participants in both free reaching and active-assist protocols. Plots C and D show the same results for subjects classified by impairment level. Error bars represent standard deviation across subjects. It should be noted that the statistics are designed to detect within-subject differences, while the figures show between-subject means and standard deviations for illustration of mean values.
