Investigating the therapeutic efficacy of microcurrent therapy: a narrative review

Microcurrent (MIC) therapy is a non-invasive, low-intensive electrical modality that remains underutilized despite evidence supporting its therapeutic potential. With applications in chronic pain, wound healing, musculoskeletal injuries, deconditioning, and neuropsychological conditions, MIC offers a pain-free alternative to traditional electrotherapies. This narrative review compiles the current literature on MIC therapy, highlighting its physiological mechanisms, such as promoting cellular repair, modulating inflammation, and reducing pain, without inducing discomfort or muscle fatigue. Though more high-quality evidence is needed, this review examines the current evidence on MIC's role in managing chronic and complex conditions across diverse healthcare environments and patient populations.
