case_images: Postprocessed sEMG signals of the monitored muscular activity from the BB and TBL muscles of a healthy subject. The curves represent the median activations of different working load profiles of 3 force levels (resistance, zero or no force, assistance) x 3 movement's speed levels: (a) low, (b) medium, and (c) high.

case_images: Then, the signals were divided into epochs using the maximum peak of the recorded FE elbow angle as a reference trigger and resampled using a cubic spline interpolation.  Figure 6 shows the average muscle profiles of a healthy volunteer under the different tested conditions.
