LOW-LEVEL LASER THERAPY (LLLT)
What Does Laser Treat?
Laser Therapy is a potential treatment for:
• Osteoarthritis, Rheumatoid Arthritis, Disc Herniation
• Tendonitis, Cartilage Injury, Muscle Strain, Ligament Sprain and Back/Neck Pain
• Any Musculoskeletal Condition to Accelerate Healing and Decrease Pain
Therapeutic lasers work by supplying energy to the body in the form of photons of light and allowing the body to effect its own repairs. Generally speaking, the biostimulating effect of laser therapy is in its anti-inflammatory, analgesic and anti-edematous effect on tissues. There is absolute increase in microcirculation, higher rates of ATP, RNA and DNA synthesis, and thus better tissue oxygenation and nutrition. There is also an increase in the absorption of interstitial fluid, better tissue regeneration and stimulation of the analgesic effect. A partial list of medical conditions which have responded well to Laser include:

Therapeutic Laser Biological Effects
- Rapid Cell Growth - Laser light accelerates cellular reproduction and growth.
- Faster Wound Healing - Laser light stimulates fibroblast development and accelerates collagen synthesis in damaged tissue.
- Increased Metabolic Activity - Higher outputs of specific enzymes, greater oxygen and food particle loads for blood cells and thus greater production of the basic food source for cells, Adenosine Tri-Phosphate (ATP).
- Reduced Fibrous Tissue Formation - Laser light reduces the formation of scar tissue following tissue damage from: cuts, scratches, burns or post surgery.
- Anti-Inflammatory Action - Laser light reduces swelling caused by bruising or inflammation of joints to give enhanced joint mobility.
- Increased Vascular Activity - Laser light induces temporary vasodilation increasing blood flow to damaged areas.
- Stimulated Nerve Function - Slow recovery of nerve function in damaged tissue can result in "dead" limbs or numb areas. Laser light speeds the process of nerve cell reconnection to bring the numb areas back to life.
Is Laser (LLT) Therapy Scientifically Documented?
There are thousands of published studies that describe the positive effects of laser therapy. These studies range from studies on individual cell types to in vivo double blind control studies. The areas of study range from wound healing to muscular skeletal conditions and have been conducted on different types of laser devices. Medicine is a very good medical database search engine that can provide abstracts and can sell literature. There are also many books on the subject. One very good text is "Low Level Laser Therapy-Clinical Practice and Scientific Background", written by Jan Turner & Lars Hode.
How Deep Can a Laser Penetrate?
The depth of penetration of laser light depends on many parameters such as the laser's wavelength, the power, the type of device driver (pulse or continuous wave mode), and lastly the technique used. The higher the wavelength typically the deeper the penetration; however, with wavelengths greater than 950nm the water in the tissue absorbs light and the depth of penetration is drastically reduced in addition to causing heat.
Secondly devices of greater power can provide better penetration. Thirdly, the peak power of the unit is the most critical factor in providing depth of penetration. Thus, devices which are true pulsed have better penetration versus continuous wave devices because they have greater peak power densities for superior photon concentrations at depth. The TLC-1000 series of Therapeutic Medical Lasers can provide a direct penetration of tissue 5 cm into tissue and an indirect penetration up to 10 cm.
Are There Harmful Side Effects?
No, although one must never shine the laser directly into the eye. Otherwise, we recommend that laser devices not be used on the abdomen of a pregnant woman, in the presence of photosensitive compounds or directly on any cancerous tissue.
