Therapeutic lasers use light waves of a specific wavelength to cause photobiomodulation, or the alteration of cellular and tissue physiology. Light absorbed by cellular components stimulates electrons and activates cells to promote growth, proliferation, migration, and repair.

 

The type and depth of tissue that responds to laser therapy depends on the wavelength of the light that is delivered. Laser beams of lower wavelengths are absorbed by superficial tissue, such as the skin, whereas beams of higher wavelengths penetrate deeper to muscles and bones.

 

Laser therapy helps tissue repair by causing the following:

• Endorphin release, triggering the body's natural painkillers

• Vasodilation, which increases blood flow to bring in oxygen and cells involved in the healing process

• Muscle relaxation

• Decreased inflammation

• Faster healing and repair

 

The main clinical benefits of laser use in pets include decreased inflammation, decreased pain, and improved wound healing. Serving as a drug-free alternative, it becomes particularly invaluable for those unable to take medications. Laser therapy finds its niche in addressing conditions such as arthritis, expediting healing post-surgery, managing tendon and ligament injuries, and fostering optimal wound recovery.
