FDA Approved Medical Technology. Low Level Laser Therapy (LLLT) has been used worldwide for over 40 years to relieve pain, remove scars, heal wounds, regenerate nerves and solve addictions. On January 17th, 2002, the first U.S. Low Level Laser Therapy (LLLT) company, Erchonia, the laser you’re being treated with, received FDA clearance through clinical trial. The study took 100 patients complaining of Neck and Shoulder pain. Half were treated with a useless red light (placebo group), similar to that on a computer mouse or grocery check-out, and the other half received LLLT. The treatment group beat the placebo group by 66%! That’s 66% faster relief and more complete relief, a remarkable margin. Such a study is known as “double blind” research, and is the gold standard for measuring the validity of a therapy. Similar studies have been passed by the FDA for Carpal Tunnel, Wounds and Scar Tissue. There are over 2000 published studies on LLLT reporting zero negative side effects.
