Low Level Laser Therapy

Low Level Laser Therapy

Low level Laser Therapy (LLLT)

Low level laser therapy (LLLT) is sometimes referred to as cold laser, soft laser or bio-stimulation laser. In essence, they all refer to one thing – healing with light.

Of course, most people, when they think of lasers tend to conjure up images of devices that can burn through metal, or they think of those that are used in surgery for surgical procedures. Low level lasers, however, don’t emit heat. They direct non-thermal photons of light into the cells of the body.

Once the light energy passes through the layers of 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 cascade 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. Laser therapy, therefore, would appear to have the potential to accelerate the regeneration of tissue. As a laser therapy practitioner, this became evident to me when treating a variety of clients, in particular, those suffering from bone fractures, when pain significantly diminished and mobility was noticeably increased; thus strongly suggesting accelerated healing. I also treated a client who was diagnosed with chronic liver failure, with a poor survival prognosis. After several laser treatments over a period of several weeks, his condition was re-assessed. The consultant concluded that there were signs of improvement as evidenced by the results of blood tests and a liver scan. This is consistent with studies conducted on laser therapy and its regenerative action on the liver cells of rats (1)

Reduction of pain and inflammation

One of the most striking benefits of cold laser treatment is its effects upon reducing pain and inflammation. A recent study conducted by British scientists  at Dundee University in Scotland (2) involving volunteers who suffered from arthritic pain reported a significant reduction in pain. The low level laser beams are thought to work by stimulating the release of endorphins . These are the body’s natural painkillers and are produced by the brain in times of pain and stress.

There is also evidence that cold laser treatment may help carpal tunnel syndrome, which is a very debilitating condition that restricts movement of the sufferer’s wrist and hand. (3)

 

Low Level Laser for Facial Rejuvenation/Wrinkles

It is perhaps no surprise that a form of light therapy that encourages cellular regeneration has the potential for rejuvenating the skin. Facial skin cells subjected to low level light frequencies have shown distinct signs of regeneration. Evidence of this effect has been shown by a number of scientific studies including one on facial rejuvenation conducted by MD, Peter Bjerring and several medical colleagues. (4)

The effects are due to accelerated tissue repair which is initiated by exposure to low intensities of red light and also infra red light frequencies.. Such exposure results in improving the metabolism of the skin cells and stimulation of collagen, the protein that gives strength to the skin (Berring et al 2002).

Low level laser therapy is also helpful in cases of skin damage due to over exposure to the sun, in addition to scarring from skin conditions such as acne, etc.

 

Light Acupuncture

The term ‘Light Acupuncture’ is sometimes used, as light beams may be directed to activate energy meridian lines and pressure points in the body, as in the Chinese Medicine system, but with the advantage of not having to use needles (2) . This is believed to activate endorphins in the brain which are the body’s natural painkillers.

The low intensity laser produces a beam of light that has a unique wavelength and frequency. These can be varied so that different parts of the body are beamed the optimum frequency for their needs.

Precise settings exist on the Quantum Laser Unit so the best healing may be facilitated. When working with clients I use the Quantum Laser machine and up to three light probes for deeper and more specific treatment.  These are violet, red and infrared. Light therapy treatment is deeply relaxing and generally very pleasurable.  Laser Light Therapy is totally safe and FDA approved for pain relief.  Only ‘natural’ low-level light is administered.

 

Other conditions helped by cold laser treatments include:

·       Stress/anxiety

·        Insomnia

·        Pain relief

·        Acceleration of tissue repair, including muscle and ligament strains and bone fractures

·        Sports injuries

·        Wound Healing
