ABSTRACT
The detection of muscular activity by surface electromyografhic (SEMG) signals has been used in different clinical applications and continues to present a research chaalenge, especially in weak muscular contraction condition with low signal to noise ratio. This work shows a comparison among three single-threshold methods and a double-threshold (DT) method for automatic muscle activity detection using a simulated SEMG signals. Latency and a contraction index were used to compare the results. Despite of some authors have reported good results with the DT method, in our results it was not observed...
