The purpose of this study was to use dynamic 4D phase contrast MR imaging to compare the stimulation patterns of neuromuscular electrical stimulation of the calf muscles when delivered through the muscle belly or through the nerve trunk. Experiments were performed on healthy volunteers and strain maps were obtained for each stimulation modality. A more homogeneous activation of the muscle group was obtained for nerve stimulation, with overall lower strain values with respect to muscle stimulation.
