Class 4 laser therapy may sound futuristic but it has become a standard of care for many musculoskeletal injuries. 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.

The wavelength 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 2-6 minutes.

The benefits of class 4 laser therapy include reduced pain and swelling as well as improved range of motion but a class 4 laser has some very interesting effects that we don’t notice as obviously. A class 4 laser increases tissue regeneration which is why you heal faster but it also accelerates soft tissue and bone repair. This kind of laser therapy can also 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).
