Educational Needs The use of “low-level” light applications termed photobiomodulation is an expanding field with a broad range of applications in medicine, rehabilitation, dentistry and veterinary medicine. To appreciate how light can have therapeutic effects on many tissues and organs it is essential to understand the molecular mechanisms involved. Experts will focus on the basics of light transmission through tissues and absorption by cytochromes in cells and tissues, and the role of signaling molecules, biological responses of cells and tissues to photons, and mechanistic convergence of photobiomodulation and clinical effects. Clinical and pre-clinical applications, including recent work on traumatic brain injury, nerve injury and repair, muscular performance and recovery and effects of photobiomodulation on stem cells will be discussed.

Participants Scientists, engineers, health care professionals, and industrial representatives interested in low level light applications.

Background Requirements Any scientist or health care provider working with energy based devices would benefit from understanding these basic light-biological interactions and how these processes may be occurring in many currently used energy based clinical modalities.

Instructional Content/Expected Learning Objectives At the conclusion of this workshop, participants will:

  • Understand the photobiological basis for light absorption by chromophores.
  • Be aware of specific wavelengths absorbed by different chromophores.
  • Gain knowledge of the depth of penetration of various wavelengths of light.
  • Be aware of the current proof for the mechanistic basis of photobiomodulation by understanding the role of different signaling molecules.
  • Appreciate the breadth of biological responses of cells and tissues after light treatments.
  • Understand how all this mechanistic proof translates to a clinical efficacy.
