Stroke or physical injuries resulting from accidents are leading causes of motor impairment. To restore motor functionality, active patient participation and involvement of neural processes are key factors. Brain-computer interface (BCI) rehabilitation systems pair the imagination of the movements with visual feedback in real-time to encourage and assess the patient’s willingness. Visual feedback through a virtual avatar can encourage the patient to correctly imagine the movements of the upper/lower extremities. The simultaneous activation of sensory and motor functions is a key factor for brain plasticity, which enables effective recovery from neurological impairments. Virtual reality (VR) can enhance brain plasticity and therapeutic outcomes by providing feedback through the visualization of motor imagery (MI) on a screen.
