Evaluation of Techniques for the Study of Electromyographic Signals

The objective of this work was the study and the development of techniques for acquiring and processing electromyographic signals that can be used for analysis of the behavior of electromyographic variables during fatiguing dynamic activities. Two of the techniques were the RMS value and the MPF, which are commonly used for the analysis of electromyographic signals measured during isometric contractions. A new technique, called MAEC, was proposed, based on the domain of the Wavelet transform. The results showed that the combination of the three techniques together with the protocol for recording electromyographic signals lead to a useful characterization of the behavior of electromygraphic variables
