In this article we present the results of a study based on continuous wavelet transforms (CWT) of surface EMG signals. This analysis provides the distribution of the energy of the signal in the time-scale plane (scalogram). The data used in this study were signals obtained from patients with low back problems, and the analysis showed that there exist visual differences between the muscle responses before and after rehabilitation, as it can be seen in the associated scalograms.
