How Does Low Level Laser Therapy (LLLT) Work?
According to Low Level Laser Therapy by Jan Turner & Lars Hode (Prima Books), LLLT:
LLLT in the 660nm wavelength appears to be antiviral, antifungal, and antiherpetic.
Laser irradiation of tissue cultures has shown that units of light energy (photons) are absorbed by enzymes, which react to light within the cell. Visible red light is absorbed within the mitochondria and the infrared light is absorbed at the cell membrane.
In a mammalian cell, this results in a change in membrane permeability, increased ATP levels and increased DNA production. The photons picked up by the cell membrane result in improved membrane stability and increased activity of the ATP dependent Na/K pump. Because cell metabolism is influenced by Na/K movement across the membrane, increasing the gradient will affect the flow of ions and hence the overall metabolism of the cell.
On a tissue level, it has been shown that irradiation by laser light results in increased collagen and epithelial production and production of new capillaries and an increase in density of the capillary bed.
Reduction of pain and inflammation results from this treatment, as does the stimulation of nerve regeneration, muscle relaxation and atonicity (lack of muscle tone). There is also an indication that laser light therapy helps to increase the immune system response.
Red light aids in the production of ATP in cells, which increases cellular health and energy. The radiation (energy) in normal cells stimulates adjacent cells to divide in the normal process of regeneration and healing. LLLT light stimulates abnormal tissue to activate normal inter-cellular radiation, thus stimulating the normal healing process to start again. The photons produced by laser light normalize tissue by activating enzymes within cells. One activated, enzymes within a cell trigger a chemical reaction in which more enzymes are activated in a domino-type effect. LLLT has no effect on normal tissue. Photons will only be absorbed by cells that need the energy.
USA today article on new uses for laser therapy. Notice the last section on pain relief applications.http://www.usatoday.com/news/health/2007-06-19-laser-therapy_N.htm
By waving the laser back and forth over a muscle or muscle group tension and pain will often be relieved in 3-5 min or less. Chronic conditions may take longer. Five minutes of laser therapy on the face will yield healthier looking skin if used daily. Hair will also respond if used for 10-20 minutes/day. Hair follicles are strengthened and new growth is stimulated by the 660nm wavelength.
Q. What is LLLT?
A. Low Level Laser therapy is the use of low intensity laser photon energy to relieve pain and enhance the body's healing/rejuvenation process.
Q. How does LLLT?
A. Photons from the laser light excite the body's cells infusing them with energy, with the three primary reactions being, reduction of inflammation, cell regeneration, and increased blood flow.
Q. What is it used for?
A. There are many applications for Low Level Laser Therapy, the most commen uses are to relieve pain and stimulate the body's own healing process.
Q. What are the benefits of lllt?
A. LLLT is a noninvasive, fast and effective modality that has been proven in clinical trials to reduce pain, reduce edema and promote healing.
Q. How safe is LLLT?
A. Low Level Laser Therapy has is very safe, the only precaution is to avoid shining the laser directly into the eyes.
Q. How deep into the tissue can laser LLLT penetrate?
A. The depth of penetration is dependent on multiple factors including mass and density, however since low level laser has been proven in clinical studies to effect subcutaneous cells; the point is low level laser does penetrate into the body.
Q. Can I use LLLT at home, on myself?
A. Low Level Laser Therapy is simple enough for any adult to use at home, at work, or on the go.
Q. Is LLLT painful?
A. No, most people do not feel anything, for those that have reported a feeling, it is nothing more than a slight tingling.
Q. Who uses the LLLT?
A. Cosmetic Surgeons, Chiropractors, Plastic Surgeons, Physical Therapists, Registered Nurses, Medical Doctors, Spas, and now YOU!
Q. How is LLLT administered?
A. The Laser Therapy pen can be used directly on the skin or held further away, as far as 2ft to cover larger areas for example neck muscles, shoulder muscles, or back muscles.
Q. How long does it take for the laser to heal or improve a condition?
A. Most people can feel a difference after the very first time using the Laser Therapy Pen. We recommend rating your pain level from 1-10, 10 being the worst, before you use the laser. Try one to three minutes on the area of pain and then rate your pain level again. Reapply as needed or until you feel relief.
Q. What's the difference between LLLT vs. LED?
A. The Laser Therapy Pen uses a super high quality industrial grade laser module that is fine tuned to 660nm along with glass optics to insure a high level of bio-stimulation and healing. LEDs are inexpensive, non-focused wide range light sources. The primary difference is in performance and depth of penetration, Laser diodes penetrate deeply, working subcutaneously, LEDs affect surface areas only .
The new Laser Therapy Pen is now available with AC power for unlimited treatment times
The powerful 50mw beam of the Laser Therapy Pen generates almost no heat. The 660nm wavelength of this laser looks hot but is cool to the touch and actually very soothing. The lline generating beam pattern was chosen so that large or small areas of pain could be dealt with easily.
