Figure 3: Overall participant performance on parameters at Level 1. Row A: solid black data line (thick) represents control participant data distribution and dashed line represents stroke participant data distribution. Shaded grey areas represent 95% of control performance. Row B: hand speed is presented in the first plot for both affected/non-dominant side for stroke (black dashed) and control (solid black) and for the unaffected/dominant side (red dashed and solid lines respectively). The number of speed peaks is shown in the next two plots in row B, separated into male (black) and female (red) groups. For both plots (as well as bar length changes in row C), significant effects of sex were found at Level 1, therefore comparisons were made with the groups split. Row D: Significant age effects were found for RT diff and Diff in path length; these parameters are plotted against age with age-corrected control percentiles (RT diff was one-tailed; 95th percentile was used, Diff path length was two-tailed; 2.5 and 97.5 percentiles were used; negative values reflect greater path length with unaffected (or dominant for control) side). No data are shown for number of drops or drops/hit at Level 1 because drops are not possible at this level.
