Veterinary laser therapy is an innovative treatment that has gained popularity in recent years as veterinarians discover its benefits for pets. Laser treatment can be used in conjunction with or in place of medication to manage pain, inflammation, and wound healing.
“Laser”—an acronym for “light amplification of stimulated emission of radiation”
How does laser therapy affect my pet’s tissue?
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 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
- 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
- Older pets with diminished organ function
How are laser treatments administered?
During a treatment session, the handheld laser wand is slowly moved back and forth over the damaged tissue, producing a warm, pleasant sensation that most pets seem to enjoy and find relaxing. Sessions usually last 15 to 30 minutes, with the number of sessions and frequency of treatments dependent on the injury.
Is laser therapy safe for pets?
Laser therapy is safe if performed correctly, using the proper settings and treatment durations.
