Microcurrents are currents that are so small that they are not discernible to the patient.
It has been used for wound-healing, pain and swelling. It is also a direct current that may restore a biological electrical balance to facilitate tissue-healing and subsequent pain control. It is also particularly useful for the treatment of increased sensitivity to pain (hyperaesthesia) and the treatment of children. Microcurrent membranes can be used at home.
