Discover the basics of RLT, also known as low-level laser therapy or Photobiomodulation, and how it differs from sunlight. How Does RLT Work? Understand the theory: How light photons interact with cells (chromophores) to potentially boost cellular energy for healing, inflammation reduction, pain relief, and even collagen production. Why Use RLT for Pain? Explore the science suggesting RLT can reduce nerve excitability and promote the release of natural pain-relieving endorphins. Evidence for Knee OA Pain: We look at a review of 13 studies (673 participants) suggesting RLT is superior to sham treatments for OA knee pain relief, despite the overall low quality of evidence. Learn how these studies compare active RLT against placebo effects. Is RLT Worth Trying for Knee Pain? Based on the research, i...
