**5. Conclusions**

WMCS has been both theoretically, clinically and experimentally, evidently proven as an e ffective, easy-to-use, non-invasive and time-e fficient treatment for the wound healing of di fferent etiopathologies, as electrode-based ES; however, with more of its advantages reflecting its contactless application. Yet, greater knowledge of the specific repairing mechanisms upon WMCS treatment will convey us toward more e ffective and broad clinical applications. To this end, more experimental and clinical e fforts are needed to elucidate how wound regeneration is influenced by the choice of optimal parameters of WMCS (i.e., polarity, frequency, duration) that could a ffect the general healing process in each medical case.
