Corrective Light Therapy

Since ancient times, it has been very well recognized that the human body reacts positively to light and that light can influence a number of important physiological processes varying from wound healing to pain control and mood regulation. Biochemical research indicate that human tissues contain a protein, cryptochrome, which reacts positively to light.
The science behind light therapy is multi-fold—useful for skin and tissue healing, relieving pain, decreasing inflammation, and helping to restore function of the tissue and cells.1

As a part of our integrative approach, we offer corrective light therapy which harmonizes body functions via exposure of specific body areas to light. The procedure uses a light emitting diode therapy (LEDT) with incoherent polychromatic LED’s running at 480-780nm.
The machine we use has four different wavelength settings that are tailored to each patient's needs.
Red light produces a wavelength that targets the cells in a way to promote aerobic activity, which works to increase metabolism of the cells to promote healing.3
Blue light is mainly used for cosmetic purposes, particularly inflammatory acne by disrupting the cell membrane of the bacteria.4
Infrared light is thought to penetrate deeper into the skin than color, so we use this in combination with other settings to promote uptake into deeper tissues.3
Green or yellow light is not employed as a primary light but are useful in conjunction with other wavelengths mentioned above.
A typical protocol incorporates 8-10 1-hour sessions 2-3 times a week. Protocols are designed and performed by our physician assistant, Neenah.

Applications of corrective light therapy include:

  • Reflex sympathetic dystrophy or regional pain syndrome
  • Peripheral neuropathy
  • Sport-related trauma or injuries
  • Pain due to shingles (post-herpetic neuralgia)
  • Poorly-healed wounds/skin and tissue healing
  • Decreasing inflammation
  • Chronic infections
  • Interstitial cystitis
  • Anxiety disorder
