Figure 6: Intrasession evolution of mean arterial pressure (MAP) and mean cerebral blood flow velocity (CBFV) in the MCA of the affected hemisphere during training session 1 (values are averaged in 3 min-time windows). (a) MAP shows an initial dip in control and ROBO-FES groups during the first 9 min of training and returned to baseline thereafter. (b) Similarly, mean CBFV only decreased in the first 6–9 min and then quickly returned to baseline. Error bars indicate SD.
