Overview of the control scheme. sEMG signals recorded from the surface electrodes were processed through some acquisition steps such as amplification and band pass filtering in order to improve the signal quality. Then, RMS values of the processed sEMG signals were compared with the customized threshold. The Arduino board classified whether to operate the orthosis according to the magnitude of the RMS value
