Bioelectricity and microcurrent therapy for tissue healing – a narrative review

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.
