Laser therapy is a process where light energy Photons enters the tissue and is absorbed by the mitochondria and the cell membrane. Mitochondria are the cell’s power centers. They allow the cell to move and divide.
Light photons act as “food” or “fuel” for your cells. Just like a plant’s photosynthesis process, your cells use the energy to grow, repair themselves and multiply. Photonic energy is converted to chemical energy within the cells of your tissue. Cell membrane permeability alters, then physical changes occur and your body begins to heal itself.
When natural light is passed through one end of a prism the result at the other end is a rainbow. Each color in that rainbow has its own wavelength or colour signature. Each type of laser also has its own wavelength or color. A device which emits a Visible Red (VR) light has a different wavelength than an Infra-Red (Invisible Red) laser. 4 5.
A laser’s light wavelength determines how deep the light will penetrate into your body. Infra-red wavelengths will penetrate deeper, and so are used for deep tissue injuries. Visible red wavelengths do not penetrate as far, and are used more for surface conditions.
Therapeutic lasers (cold lasers) can create a variety of effects on your tissues. These include:
Your body uses a laser’s energy to heal itself. Noticeable results often take up to 48 hours. Within two days you should notice reduced pain and increased mobility.
For lasting, long-term benefits your healthcare provider will probably recommend several laser sessions in a treatment plan designed specifically for your condition(s).
No. Laser therapy is not masking or blocking pain temporarily. By “feeding” your cells, lasers speed up the natural healing process so that damaged cells can actually heal themselves.
Healing takes time and as you progress, you could experience more or less pain/discomfort as your body recovers
Yes. Over 3000 research articles have been published about the effectiveness of laser therapy for various conditions. In fact, laser therapy has the most published research of any form of electrotherapy. Cold laser therapy is commonly used in medical, physiotherapy, podiatric, chiropractic, osteopathic, acupuncture, dental and veterinary clinics.9
