Here, we apply a discrete approach to the same problem of decoding the human gait. By reducing the gait process to a mere succession of Stance and Swing phases for each foot, the average decoding accuracy reached 93.71%. This is sufficient to design a gait descriptor that relies only on this classification of two possible states for each foot over time as input, which could complement the model-based continuous decoding method that lacks in some aspects (foot placement at landing, weight acceptance, etc.). A final implementation of this method could be used in a powered exoskeleton to help impaired people regain walking capability.Brain-Computer Interface in RehabilitationNeural Prostheses in RehabilitationNeuro-Robotics in Rehabilitationtext::conference output::conference proceedings::conference paper
