What is Class 4 Laser Therapy?

Class 4 laser therapy uses specific wavelengths of light (red and near-infrared) to create therapeutic effects. The light that is transmitted via the laser helps stimulate certain processes within the body that help provide relief to symptoms including pain, swelling, and limited range of motion. 

How does Class 4 Laser Therapy Work?

The wavelengths of the laser used in Class 4 laser therapy penetrates deeper and more efficiently than the Class 3 laser allowing it to pass energy to the nerve, muscle, ligament, and tendon tissue in a short amount of time. In fact, most sessions range from 8-12 minutes which means we can treat injured tissue in multiple areas in a single session thus improving your results. 

Class 4 laser therapy stimulates the production of ATP (adenosine triphosphate) which drives many of the processes within our cells. This increased production of ATP helps speed up the healing process within cells. As a result of increased ATP production the patient experiences an improvement of symptoms, reduced pain and  swelling, and range of motion and of course, the heat from the laser is soothing as well.

Class 4 Laser Therapy Benefits

The benefits of class 4 laser therapy include:

  • reduced pain and swelling as well as improved range of

  • increases tissue regeneration which is why you heal faster but it also accelerates soft tissue and bone repair.

  • improve nerve regeneration & function as well as impact your cells to increase cell metabolism, enzymatic responses, collagen production, and promote angiogenesis (the creation of new blood vessels).


You walk away from class 4 laser therapy feeling better but the therapy continues to work on the cellular level to improve your musculoskeletal health after you leave the office.

We use class 4 laser therapy on a range of issues including neck and back pain, disc and nerve issues, and chronic joint pain and degeneration.
