Motor imagery (MI) based on brain computer interfaces (BCIs) have been widely applied for upper limb motor rehabilitation. Due to the fact that a large number of disabled people need to restore or improve walking ability, it is also important to investigate the use of MI-based BCIs for lower limb motor rehabilitation. The brain activity of lower limb MI is more difficult to detect because of low reliability...
This work presents an electroencephalography (EEG)-based Brain-computer Interface (BCI) that decodes cerebral activities to control a lower-limb gait training exoskeleton. Motor imagery (MI) of flexion and extension of both legs was distinguished from the EEG correlates. We executed experiments with 5 able-bodied individuals under a realistic rehabilitation scenario. The Power Spectral Density (PSD)...
In this paper, a functional interface between brain and central pattern generator (CPG) is designed in an engineering perspective, which may serve in a human-machine system. Steady-state visual evoked potential (SSVEP) based brain-computer interface (BCI) is used to recognize five types of intention related to human walking. After feature extraction, classification and command translation on electroencephalography...
