Microcurrent has some very beneficial effects on injured tissue healing that are well documented.
Portable microcurrent equipment is applied during a clinic session and can often be taken home by the patient for continuous use over a number of days. Alternatively, a series of in-clinic treatment sessions can be arranged.
Below is a small sample of the literature on the use of microcurrent:
