BCI-assisted motor imagery training (BCI-MI, experimental intervention)
SPINAL CORD
An all-in-one BCI-supported MI training station (Fig. DiSCIoser BCI station. The Brain-Computer Interface training station developed for patients with Spinal Cord Injury to practice the kinaesthetic motor imagery of hand closing and opening in a close-loop condition. The system is equipped with a laptop, a commercial wireless EEG/EMG system and a screen for the ecological feedback to the participant. The ecological feedback is delivered by means of a custom software program that provides for (personalized) visual representation of the participant’s own hands. The screen for the feedback is adjustable in height and tilt to adapt to use in wheelchair or bed. The participant in the photo filled out the photo release consent formThe feedback that participants receive, i.e., their own hand opening or closing in the virtual environment, will be controlled by the BCI control features. They are those relevant, significant frequency/spatial changes of the EEG signals related to the MI task. The control features will be extracted through offline analysis of the MI-related EEG data collected at A semiautomatic, physiologically driven EEG feature selection method, GUIDER algorithm [
