Amplitude and frequency analysis for EMG. (a) EMG example for patient 3 sessions data segmentation into epochs of 2 s with an overlap of 1 s (b) Time evolution of all patients average RMS calculated for each epoch. The shadow of the line corresponds to the standard error of all patients in the time series. (c) For each epoch, power spectral analysis was performed, and the mean frequency was calculated. (d) EMG average normalized power spectral density across all patients for PRE, MTI, and POST. The average mean frequency across patients is marked with a black line. The behind shadow plot represents another period power spectral analysis. The three plots share the same axes. (e) Box plots summarizing the distribution of MNF and RMS values obtained from individual recordings during the MT intervention. Black lines indicate significant differences between periods (*p-value < 0.05, **p-value < 0.01).
