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.
Laser therapy helps tissue repair by causing the following:
- Endorphin release
- 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.
Who can benefit from laser therapy?
Laser therapy is used for many veterinary medical conditions, including:
- Chronic arthritis
- Surgical incisions
- Tendon and ligament injuries
- Traumatic injuries
- Laser therapy is particularly useful for pets with limited medical treatment options, such as:
- Pets with liver disease who cannot take medications
- Cats, for whom only a few pain-control medications are approved
- Exotic pets for whom medication administration is difficult or impossible
- Older pets with diminished organ function
