Figure 3.

Changes in EEG discriminant rate in two groups before and after intervention. Significant increase in the discriminant rate based on the ipsilesional EEG signals was found after training compared to the baseline in Robot_{EEG_AO} group. No significant change was found in Robot_{non−EEG_Text} group in either the ipsilesional or the contralesional discriminant rate. The color bars indicate the average discriminant rate values across the subjects in each group. DR stands for discriminant rate. Error bars stand for the standard deviation. Asterisk (*) indicates that significant difference between pre- and post-training was observed at p < 0.05.
