Key Takeaway
Comprehensive review confirms PEMF has measurable biological effects through ion channel modulation, nitric oxide signaling, and gene expression changes, with clinical applications in bone healing and wound repair.
Summary
This comprehensive review examined the scientific literature on pulsed electromagnetic field (PEMF) effects on biological systems.
PEMF works through plasma membrane depolarization, triggering calcium ion channel opening, nitric oxide production, and downstream gene expression changes. Clinical applications include bone healing, inflammation modulation, and wound repair.
