Photobiomodulation Lecture 2015 (Low Level Light Therapy)
Photobiomodulation Laser Therapy
Watch as Dr Lew Lim and leading scientists from Harvard Medical School and Boston University School of Medicine, share their insights about the positive effects of low level light therapy(photobiomodulation) on the body and brain at the cellular level.
This is the groundbreaking webinar on photobiomodulation that aired during the World Summit of Integrative Medicine 2015.
The therapeutic effect of light for disease treatment has been recognized for many centuries. In the early part of the 20th century exposure to sun and other natural light was commonly used to treat diseases such as dementia, tuberculosis, lupus vulgaris and acne. Currently UV light is used to treat patients with rickets (vitamin D deficiency), neo-natal jaundice, pain and a range of dermatological disorders.
The use of “low level” light applications, termed photobiomodulation (PBM), as a noninvasive, neuro-restorative therapy has potential to revolutionize repair of the injured nervous system. Experiments on the use of PBM to repair injured spinal cords and peripheral nerves will be discussed, along with the scientific basis for this improvement.
Light applied transcutaneously penetrates to the level of the spinal cord. Transmission spectra revealed that peak transmission through all tissue layers overlying the spinal cord was at 810 nm, with minimal absorption by blood and water. Axonal regeneration and functional recovery in various models of spinal cord injury was supported by 810 nm wavelength light. Genes involved in the immune response, cellular proliferation and growth factor receptors were significantly altered by PBM after spinal cord injury.
Recent data on trans-cranial light penetration into human cadaver brains will be presented, along with a review of current pre-clinical and clinical trans-cranial light applications for brain injury. Peripheral nerve injury results in chronic loss of sensation and motor function. PBM supports statistically significant improvements in nerve regeneration and functional behavior.
