EMG APPARATUS AND METHOD FOR DETECTING GAIT PHASE USING EMG SIGNAL GRAPH MATCHING ALGORITHM

摘要

Embodiments include a training EMG signal acquisition unit for obtaining an EMG signal from the EMG sensor attached to the lower body of the walking subject; A training pressure signal acquisition unit for obtaining a pressure signal from the pressure sensor attached to the subject's foot; Training EMG signal classification unit for classifying the EMG signal in each step of walking based on the obtained EMG signal and the pressure signal; And a training reference data processing unit storing the classified EMG signal for each walking step in a database as a reference EMG signal for each walking step, wherein the walking step includes initial contact, mid stance, and propulsion. A walking step detection apparatus using an EMG signal graph matching (ESGM) algorithm and a feature extraction method using the same are characterized in that each walking step includes a swing and is determined based on the pressure signal.
