An EEG Tool for Monitoring Patient Engagement during Stroke Rehabilitation: A Feasibility Study

Figure 5

Comparison of the temporary functional change between the sessions in which the BEI was higher for each patient and the sessions in which the BEI was lower for each patient. As each patient participated in two sessions, one of them had by definition higher BEI than the other and the data in the figure aggregates all sessions with higher BEI and all sessions with lower BEI over patients. For some patients the session with higher BEI was the feedback session, while for other patients the session with higher BEI was the no-feedback session. The -axis shows the percentage of patients with a session temporary functional change index above thresholds, which are presented in the -axis. This BEI-based comparison revealed a significant difference in temporary functional change ().
