5. Fig. 4
Percentage of patients with hemiplegia with an increase in (A) CBV or (B) COV at the end of each task. The percentage of patients who presented with increased CBV or COV differs significantly among 13 tasks (χ2 test). *n = 13; †n = 14; ‡n = 15; §n = 16; ∥n = 17; ¶n = 18; #n = 21; **n = 22; ††n = 24; ‡‡n = 25.

6. Fig. 5
Cerebral hemodynamics and oxygenation for each task in patients with hemiplegia. Changes in CBV and COV at the end of each task were plotted. The vertical and horizontal error bars indicate SEM.

7. Fig. 6
Changes in (top) CBV and (bottom) COV in patients with hemiplegia for 4 representative tasks: (A) HUT, (B) ergometer, (C) Romover, and (D) calculation. Open circles indicate mean levels, and vertical error bars indicate SDs. *p <.05, Wilcoxon sign test versus baseline. †p <.01, Wilcoxon sign test versus baseline.
