“…Applying the identical protocol to all participants, we detected quite a heterogeneous pattern of increased MRI-signalindicating areas of high muscular activation among the participants. Differences related to gender, skinfold/subcutaneous thickness [29], leg shape, which influence the contact of the electrodes to the tissue and the current flow, individual location of muscle motor points [17] and specificity of fiber composition [30] might have contributed to this finding. Furthermore, different stimulus thresholds of the muscles with resulting differences in contraction strength, as well as differences in the stress resistance of the muscles with resulting variations in the level of damage of muscle structures may have been a reason for the less homogeneous (nonselective) pattern in our cohort of novice WB-EMS applicants [23,31].…”

Whole-body electromyostimulation (WB-EMS) is an innovative training method that stimulates large areas simultaneously. In order to determine the spatial distribution of WB-EMS with respect to volume involvement and stimulation depth, we determined the extent of intramuscular edema using magnetic resonance imaging (MRI) as a marker of structural effects. Intense WB-EMS first application (20 min, bipolar, 85 Hz, 350 µs) was conducted with eight physically less trained students without previous WB-EMS experience. Transversal T2-weighted MRI was performed at baseline and 72 h post WB-EMS to identify edema at the mid-thigh and lower leg. The depth of the edema ranged from superficial to maximum depth with superficial and deeper muscle groups of the mid-thigh or lower leg area approximately affected in a similar fashion. However, the grade of edema differed between the muscle groups, which suggests that the intensity of EMS-induced muscular contraction was not identical for all muscles. WB-EMS of the muscles via surface cuff electrodes has an effect on deeper parts of the stimulated anatomy. Reviewing the spatial and volume distribution, we observed a heterogeneous pattern of edema. We attribute this finding predominately to different stimulus thresholds of the muscles and differences in the stress resistance of the muscles.
