REINVENT: A low-cost, virtual reality brain-computer interface for severe stroke upper limb motor recovery

摘要

There are few effective treatments for rehabilitation of severe motor impairment after stroke. We developed a novel closed-loop neurofeedback system called REINVENT to promote motor recovery in this population. REINVENT (Rehabilitation Environment using the Integration of Neuromuscular-based Virtual Enhancements for Neural Training) harnesses recent advances in neuroscience, wearable sensors, and virtual technology and integrates low-cost electroencephalography (EEG) and electromyography (EMG) sensors with feedback in a head-mounted virtual reality display (VR) to provide neurofeedback when an individual's neuromuscular signals indicate movement attempt, even in the absence of actual movement. Here we describe the REINVENT prototype and provide evidence of the feasibility and safety of using REINVENT with older adults.
