Abstract：There are various surface electromyography（sEMG） analysis methods，as time domain，frequency domain，parameters model，time-frequency domain，nonlinear dynamics domain and so on. Aiming at choosing method to analysis sEMG， after analyzing various analysis methods，the features，advantages and disadvantages，use case of those methods were compared. The results indicate that every method has its own characteristics and should be selected according actual situation. With in-depth research，sEMG is widely used in rehabilitation medicine，especially in rehabilitation evaluation，prosthetics and rehabilitation robotics.
Key words： surface electromyography（sEMG）； signal analysis and process； time-frequency domain； rehabilitation medicine； evaluation of rehabilitation；rehabilitation robotics
