| Abstract: | Electromyography (EMG) signal analysis has great value in the fields of clinical diagnosis, rehabilitation, bionic control, engineering application and so on, while feature extraction is the basis of EMG signal analysis. After reviewing such methods that are used to extract the characteristics of EMG signals, the paper concluded four main kinds of methods: time-domain, frequency-domain, time-frequency and nonlinear dynamics analysis methods. Based on a brief introduction to above methods, the paper compares the advantages and disadvantages of each method and predicts their application prospects in the correlative fields of EMG analysis. |
