Low Level Laser Therapy
Low Level Laser Therapy (LLLT) or Cold Laser Therapy is a treatment that uses specific wavelengths of light to interact with tissue and is thought to help accelerate the healing process. It can be used on patients who suffer from a variety of acute or chronic conditions to help eliminate pain, swelling, reduce spasms and increase function.
The laser is placed directly over the injured area for seconds to minutes, depending on the size of the area being treated and the dose administered. Additionally, the laser can be used to stimulate acupoints for those patients who can not tolerate needles.
During this time, non-thermal photons are emitted from the laser and pass through the skin. This light has the ability to penetrate 2 to 5 centimeters below the skin in the 800-900 nm range.
Once the light energy passes through the skin and reaches the target area, it is absorbed and interacts with the light sensitive elements in the cell. This process can be compared to photosynthesis in plants - sunlight is absorbed by plants, which is then converted to usable energy so that the plant can grow.
When cells absorb this light energy, it initiates a series of events in the cell that is theorized to eventually result in normalizing damaged or injured tissue, a reduction in pain, inflammation, edema and an overall reduction in healing time by increasing intracellular metabolism.
Some of the more common conditions treated include cruciate injury, osteoarthritis, intervertebral disc disease, sterile cystitis, and hip dysplasia.
