Post-training change scores from baseline attained by sub-acute and chronic participants post-stroke after robot therapy (R, white circles) and control intervention (C, gray circles). Circles and whiskers represent, respectively, mean change score and 95% confidence interval adjusted for baseline score through ANCOVA procedure. * p < 0.05 (R versus C, ANCOVA test).
