LED Therapy

The idea behind red light therapy for pain is that infrared light penetrates the skin without cutting it.

There is evidence that infrared light stimulates mitochondrial functioning.   The mitochondria is the part of the cell that stimulates healing and produces protein and collagen.

 

Recent research has shown that this type of therapy can work to help reduce inflammation. A triple-blind study of mice has shown that neuropathic pain due to inflammation was significantly decreased with the use of red light therapy.

What is Red Light Therapy for Pain?

Red light therapy for pain is known by a number of different names, including:

  • Low level laser or low level light therapy (LLLT)
  • Low intensity light therapy (LILT)
  • High intensity light therapy (HILT)
  • Photobiostimulation
  • Biostimulation (BIOS)
  • Photobiomodulation
  • Photonic stimulation
  • Photorejuvenation

By any name, red light therapy for pain uses an infrared light to penetrate into the body’s tissues. Higher frequencies move deeper into the body, but generally the light penetrates the skin approximately two to ten millimeters deep. For chronic pain, wavelengths between 800 and 1200 nm are generally recognized as therapeutic among proponents of this treatment.

There is more than one type of red light therapy for pain. The two most common types of red light therapies are:

Low intensity light therapy: Uses a Class III laser. Generally recognized as safe and poses little to no risk for adverse effects (burns, tissue damage, etc.). There is very little research on this type of therapy. Claims of efficacy are largely anecdotal.

High intensity light therapy: Uses a Class IV laser. More scientifically-valid studies using this type of laser, but this laser poses more risks to both patient and clinician.
