How Laser Therapy Works
Photobiomodulation works through the mitochondria within cells. Our cells—and those of animals, plants and fungi—contain tiny structures called mitochondria that generate the energy we need. Mitochondria have a chain of proteins that juggle electrons, and one of them, cytochrome c oxidase, contains heme and copper that absorb light, especially in the red and infrared part of the light spectrum. So, we shine one such light on living tissue: it gets absorbed by mitochondria’s cytochrome c oxidase, and we get a veritable biological domino effect that seemingly benefits every part of the organism.
Adding post-surgical photobiomodulation to a standard anesthesia and analgesia protocol reduced pain scores and increased the proportion of animals that resumed eating compared to the standard protocol alone.
