Photobiomodulation Therapy in Diabetic Foot Ulcers: A Review of Cellular and Clinical Effects

This article reviews the role of photobiomodulation therapy (PBMT) in treating diabetic foot ulcers (DFUs), a common complication of diabetes that can lead to delayed healing and infection. The paper explains how PBMT, using low-level red or near-infrared light, may improve wound healing by stimulating cellular repair mechanisms and reducing inflammation.

Key points:

  • Improves wound healing – PBMT may enhance tissue repair by promoting fibroblast activity, collagen synthesis, and angiogenesis (formation of new blood vessels).
  • Reduces inflammation – Light therapy may help regulate inflammatory responses, which is important in chronic diabetic wounds.
  • Boosts cellular energy – PBMT stimulates mitochondria, increasing ATP production that supports cell regeneration and healing.
  • Antimicrobial and circulation effects – Some evidence suggests PBMT may improve local blood flow and reduce infection risk.
  • Clinical potential for diabetic foot ulcers – PBMT may serve as an adjunct treatment alongside standard wound care to speed healing and reduce complications.
  • Need for standardization – The review notes that more clinical studies are needed to establish ideal wavelength, dosage, and treatment protocols.

Simple takeaway:
Photobiomodulation therapy shows promise as a supportive treatment for diabetic foot ulcers by improving healing, reducing inflammation, and enhancing cellular repair, but standardized clinical guidelines are still needed.
