Laser Therapy

Red light therapy is used to treat pain by means of infrared light to penetrate into the body’s tissues. Generally, the light penetrates the skin approximately two to ten millimeters deep, but higher frequencies can move deeper into the body. For those experiencing chronic pain, it is generally recognized as therapeutic when wavelengths between 800 and 1200 nm are used for treatment.

The two most common types of red light therapies are:

  • Low-intensity light therapy – This type of light therapy uses a Class III laser and is generally considered safer and poses little to no risk for adverse effects
  • High-intensity light therapy – This type of light therapy uses a Class IV laser and is used by more scientifically-valid studies, but poses more risks to both patient and clinician
