Laser therapy is a type of photobiomodulation therapy that utilizes specific wavelengths of red and near-infrared (NIR) light to boost the production of cellular energy. Red and NIR light have been shown to increase production of ATP (adenosine triphosphate), which is responsible for the transport of energy in and out of cells. Higher levels of ATP from photobiomodulation therapy help increase the body’s natural healing processes, such as encouraging cell proliferation and temporarily widening blood and lymphatic vessels to allow inflammatory mediators to damaged areas. 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:
(note cells and tissues functioning normally are not affected)
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.
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
