Stroke Rehabilitation BCIs represent one of the most clinically impactful applications of brain-computer interface technology. These systems enable patients with motor impairments to engage in motor imagery-based rehabilitation, promoting neuroplasticity and functional recovery through closed-loop feedback systems that bridge the gap between brain intention and motor output[@dobkin2011].
Technology Overview
Motor Imagery-Based Rehabilitation
Stroke BCIs typically employ motor imagery (MI) paradigms where patients mentally rehearse movements without physical execution. The BCI detects motor intention from EEG signals and translates this into control signals that drive:
Visual feedback: Virtual reality environments showing avatar movement
Robotic assistance: Exoskeletons that facilitate actual movement
Electrical stimulation: FES to activate paralyzed muscles
Auditory feedback: Sound cues reflecting movement intention
Signal Acquisition Modalities
Scalp EEG: Non-invasive, suitable for home rehabilitation
Intracranial EEG: Higher resolution for research applications
