Bioelectricity and Microcurrent Therapy for Tissue Healing – A Narrative Review

Poltawski, L and Watson, T:Physical Therapy Reviews2009 VOL 14 NO 2 (105-114); School of Health and Emergency Professions, University of Hertfordshire, Hatfield, AL10 9AB, UK.

Background: Microcurrent therapy (MCT) uses electric currents similar to those produced by the body during tissue healing. It may be a particularly beneficial where endogenous healing has failed.

Aim: To review evidence regarding microcurrent in tissue healing and the application of MCT.

Methods: All peer-reviewed studies concerning microcurrent and MCT were sought, and representative literature was synthesized to indicate the scope and weight of current evidence.

Results: Microcurrent appears to play a significant role in the healing process, and MCT can promote healing in a variety of bone and skin lesions. The evidence for other tissues is encouraging but presently scant. 

Summary: MCT may have unrealized potential in the treatment of dysfunctional tissue healing and deserves greater attention by researchers and clinicians. 

Conclusions: The evidence in support of MCT is convincing enough to justify its inclusion in the clinician’s repertoire for treatment of several examples of recalcitrant bone and skin lesions.
