There is a discontinuity in published electromechanical delays (EMD) in upper-limb muscles and the state-of-the-art in modelling end-point force from electromyographic signals collected from one or more muscles. Published values are typically in the range of 10 to 30ms, depending on the nature of the contraction. In published literature where the EMG-force relationship is modelled, generally a delay...
Interferential current therapy is a noninvasive therapy using simultaneously two or more medium-frequency currents passing through tissue. By controlling the interfered area of the current flows, selective stimulation is possible in target muscles, including deep muscles. However, controlling the interfered area or the intensity of the current precisely is still lacking. Using simulations based on...
A simulation of the muscle activation, contraction and movement is here presented. This system was developed based on the Bidomain mathematical model of the electrical propagation in muscles. This study shows an electrical stimuli input to a muscle and how this behave. The comparison between healthy subject and patient with muscle activation impairment is depicted, depending on whether the signal...
