I did a Google search on red light therapy, and I found this page. I am very grateful for the wealth of information. Thank you Rebe for Anodyne Therapy also known a MIRE infrared therapy. I do red light therapy in physical therapy. I had exchange many red light therapy devices on Amazon and NovaaLabs . NovaaLabs really "no va" ( does not work )because I was burned in a 5 minutes session with their NovaaLabs Extra Strength Healing Laser. Hatch, Bestqoool, LifePro are all the same -glorified heating pads that are claiming medical grade; it made my inflammation in my joints worse not better. Because of Rebe's posts , I learned about Anodyne and bought a used Anodyne therapy device. My physical therapist dr proved of it and we are seeing results.Anodyne is a medical company that has had a patent since the 90s and they are the lead company for infrared therapy. Consult them to see if your medical condition would benefit from that type of laser treatment. I found medical research of doctors, physical therapist, nurses and other medical professionals, urging Medicare and insurance companies to continue to cover services using this device, and for covering the home version of this device. The success stories are very encouraging. Insurance companies did not want to cover it because it's a very expensive device; it still is. The insurance came out with "interesting" research, saying that it was just as good as a placebo yet many patients from all types of ailments have improved.
