Laser therapy1 is the term most commonly used to describe the therapeutic application of laser light at low intensity. In general, laser therapy is given at gentle, non-ionizing wavelengths within the red to near-infrared portion of the spectrum and at modest output powers below the threshold of heat damage to tissue2.
An adverse reaction has never been documented in over fifty years of clinical and research use, perhaps because of the gentle intensity and long wavelengths. More than 5,000 studies and articles have been published.
Results have been stunning!
What can laser therapy treat?
Because of fundamental effects of low intensity lasers (and other methods of biomodulation) to add energy to cells, perhaps nearly any health condition is likely to benefit. Positive results have been documented in:

1“Low level laser therapy”, “low intensity laser therapy”, “laser photobiostimulation” and “low power laser therapy” are a few of the other terms which have also been used. Recently “laser phototherapy” has been proposed as a more accurate name to differentiate treatment with low intensity, coherent, monochromatic light from surgical or other high powered applications.
2The exception to this is Class IV therapeutic lasers which have positive biostimulatory effects but also heat tissue to a greater degree and carry higher risk. High Power Laser Therapy or High Intensity Laser Therapy are terms which have been suggested to distinguish these treatments.
