About the webinar: Photobiomodulation Therapy (PBMT) is the use of light, either LED or laser, of different wavelengths to initiate multiple physiological effects, which can modulate pain. There are over 3,000 published studies examining the mechanisms for the pain relieving effects of light. In the somatosensory nervous system laser applied transcutaneously acts to block action potentials and to reduce fast axonal flow acting selectively on Aδ and C fibres. Laser also acts on the inflammatory cascade to reduce PGE2 and other inflammatory cytokines. In some animal studies anti-inflammatory effects of laser are equivalent to drugs such as Diclofenac. Laser can stimulate the lymphatic system to reduce oedema relevant in acute injury, including post-operatively and also in chronic lymphoedema. Laser and LED initiate tissue repair in acute and chronic injury models by stimulating activity in macrophages, neutrophils, fibroblasts and other cells leading to optimal tissue recovery. Painful trigger points and muscle spasm are also modulated by light. Each of these mechanisms has direct effects on modifying clinical pain, predominantly nociceptive, but also neuropathic pain. The potential of photobiomodulation to reduce pain and limit the need for opioid medication opens a new field of photomedicine in pain management for office based practice as well as hospital-based care.
- Describe the most important characteristics of light as medicine
- Summarize the effect of light in the somatosensory nervous system most relevant to pain relief
- Describe the broad range of tissue effects initiated by light which modulate pain
- Evaluate the experimental and clinical evidence base for application in clinical practice
- Identify patients most likely to respond to PBMT
