We introduce REVIRE (REhabilitation in VIrtual REality), an immersive virtual reality platform for post-stroke upper limb rehabilitation with integrated EEG recording. REVIRE immerses users in a 3D virtual environment where they can practice motor tasks that reflect everyday activities while providing comprehensive performance data with synchronized hand trajectories and EEG signals. Our proof-of-concept study tested the application on four healthy individuals across multiple training sessions. We observed significant effects of training on performance, evidenced by reduced task completion times. Changes in performance coincided with a decrease in EEG sensorimotor activity, consistent with existing motor learning research. In addition, the low incidence of cybersickness reported by participants indicates a comfortable and user-friendly experience, making our setup suitable for patient use. Our preliminary f indings demonstrate the suitability of our virtual reality platform for BCI-based motor rehabilitation for clinical environments and beyond.
