Class IV Laser Therapy (Photobiomodulation)

What is Laser Therapy (Class IV Laser)?

Deep tissue laser therapy is a scientifically proven way to reduce pain and inflammation. Laser therapy utilizes near-infrared (NIR) laser light to stimulate the mitochondria of the body’s cells and boost the production of ATP, which is responsible for the transfer of cellular energy. This stimulation through NIR laser therapy has been shown to treat common conditions, such as reducing pain and inflammation. Laser therapy treatment is painless and non-invasive procedure that promotes the natural healing of the body. Sessions range anywhere from 4 – 15 minutes. If you’re looking for other options besides drugs or surgery, laser therapy might be a great option for you.

Summary of the Photochemical Process:

Absorbed in Mitochondria and Cell Membrane within cytochromes and Porphyry's
Singlet Oxygen is Produced
Changes in Membrane Permeability
ATP Synthesized and DNA Produced
Increase in Cell Metabolism from a Depressed Rate to a Normal Level
Selective Bio-Stimulatory Effect on Impaired Cells
(note cells and tissues functioning normally are not affected)
Photochemical Action

Studies have shown that when tissue cultures are irradiated by lasers, enzymes within cells absorb energy from laser light. Visible red light and near infrared (NIR) are absorbed within the mitochondria and the cell membrane. This produces higher ATP levels and boosts DNA production, leading to an increase in cellular health and energy.

Therefore, when applied as treatment, lasers have been shown to reduce pain and inflammation as well as stimulate nerve regeneration, muscle relaxation, and immune system response. Lasers have no effect on normal tissues because photons of light are only absorbed and utilized by the cells that need them.

Role of Chromophores

Chromophores are components of various cells and subcellular organelles which absorb light. The stimulation of chromophores on mitochondrial membranes incites the production of ATP. This results in:

  • Increased cellular energy levels
  • Pain relief
  • Accelerated cellular healing
