BCI With Virtual Reality for Stroke Rehabilitation: A Crossover Study
Sponsor: Technical University of Lisbon
Summary
The goal of this clinical trial is to investigate if training sessions of motor imagery associated with brain-computer interface and motor observation through virtual reality (MI-VR-BCI) can help to improve arm and hand recovery after a stroke. The main questions to answer are: * Can adding MI-BCI-VR sessions improve upper limb movement? * Can it help stroke survivors perform daily activities more easily? * Does this type of training improve brain activity and connections related to movement? Researchers will compare this type of intervention with motor imagery associated with a standard brain-computer interface intervention (MI-BCI) to see if there are added effects to upper limb function, activity and brain connections. Participants will : * Perform two intervention periods in a random order: one with MI-VR-BCI training sessions and other with MI-BCI training sessions. Each period will involve 3 weekly sessions of training, during 6 weeks, with the intervention periods being separated by 3 weeks. * Complete four assessment sessions: one at the beginning and another at the end of each intervention period.

Interventions
Motor Imagery-based Brain-Computer Interface coupled with Virtual Reality (MI-BCI-VR)
The training paradigm will involve motor imagery coupled with EEG-based BCI control and immersive virtual reality (VR) feedback. VR feedback will consist of NeuRow, a first-person perspective training paradigm that allows multimodal visual, auditory and haptic feedback through the use of immersive virtual reality headset and haptic controllers. Sessions will have a frequency of 3 times per week, during 6 weeks.
Motor Imagery-based Brain-Computer Interface (MI-BCI)
The training paradigm will involve motor imagery combined with EEG-based BCI control using a cue-based visual paradigm. Sessions will be conducted three times per week over a period of six weeks.
