Poltawski, Leon & Watson, Tim. (2009). Bioelectricity and microcurrent therapy for tissue healing-a narrative review. 

Physical Therapy Reviews. 14. 104-114. 10.1179/174328809X405973. 

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 synthesised 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. 

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