Table 3. Outcomes per task of each group.

Median ±indicates standard deviation across participants. Total Learning: average reaching angle for the last 40 trials of perturbation minus the first 40 trials of the baseline, End Perturbation: average reaching angle for the last 40 trials of perturbation, Early Retention: first 40 trials of the retention block. Subgroup analysis: participants from both stroke groups with matched Baseline performance.
