Cold Laser Therapy

Does Cold Laser Therapy Really Work?


Laser Therapy, or “photobiomodulation”, is the use of specific wavelengths of light (red and near-infrared) to create therapeutic effects. These effects include improved healing time, pain reduction, increased circulation and decreased swelling. Laser Therapy has been widely utilized in Europe by physical therapists, nurses and doctors as far back as the 1970’s. Now, after FDA clearance in 2002, Laser Therapy is being used extensively in the United States.

Has effectiveness been demonstrated scientifically?

Yes. There are thousands of published studies demonstrating the clinical effectiveness of Laser Therapy. Among these, there are more than one hundred rigorously controlled, scientific studies that document the effectiveness of Laser Therapy for many clinical conditions.

Cellular Effects of Laser Therapy

During Laser Therapy the infrared laser light interacts with tissues at the cellular level, and metabolic activity increases within the cell, improving the transport of nutrients across the cell membrane. This initiates the increased production of cellular energy (ATP) that leads to a cascade of beneficial effects, increasing cellular function and health.

Laser Therapeutic Effects

During each painless treatment, laser energy increases circulation, drawing water, oxygen, and nutrients to the damaged area. This creates an optimal healing environment that reduces inflammation, swelling, muscle spasms, stiffness, and pain. As the injured area returns to normal, function is restored and pain is relieved.

What is a Class 4 therapy laser?

Lasers are classified according to their output power. A Class 4 laser has more than 500 milliwatts of power. Higher power means it can deliver more energy per unit of time – which means your Veterinarian can treat a very large area on your pet in just a few minutes.

Post Surgical Cold Laser

We recommend at least two K-Laser treatments after surgery for all of our patients. The cold laser therapy helps manage pain and also helps speed up the healing process. Laser therapy uses specific wavelengths of light (red and near-infrared) to stimulate the body’s natural healing response, the effects of laser energy also include ​pain reduction, increased circulation and decreased swelling. Overall, adding the K-Laser after surgery will decrease your pet’s recovery process and have them back into their normal routine in no time.
