In this video, you will see one of the best graphic representations of the photobiomodulation process including the release of ATP, NO, ROS.
This video was created by LightCure so at the end of the video, they try to make the point that class 4 laser are better than class 3 system. With the release of high-power class 3b (with power levels over 15 watts) system, this part of the video out of date.

This video discusses the basics of Low Level Laser Therapy. You will learn a little bit about lasers and laser history, and what makes a cold laser a cold laser. It also talks about the difference between lasers and LED's and why the latter may be less effective for medical therapy.
You'll find information on the treatment parameters of LLLT which are:
It also goes over what indications the FDA has approved LLLT and infrared light for.

Veterinarian Ron Hirschberg tells of how he first experienced laser therapy on his own arthritis, and decided to invest in lasers for his practice. Since he started using laser therapy on the pets he works with he has seen many positive results, he explains that gross profits from NSAIDs decreased from 0.71% to 0.3%, and laser profit now makes up 4% of the practice's income. He will treat between 3 and as many as 13 patients with LLLT, 95% of which he says improve noticably faster than those without LLLT.

Lasers as a medicinal tool have been researched ever since their discovery forty years ago. LASER is the acronym for Light Amplification by Stimulated Emission of Radiation. Albert Einstein was the first person to discover the presence of laser; however it was Theodre Maiman who invented the first working ruby laser. He managed to produce a red colored laser from ruby crystal which was so intense that it could bore through several layers of stacked razor metals. The laser produced was powerful but short-lived. Since then much research has taken place in this area.
Low level lasers are characterized by low intensity levels and were used by Endre Mester, a Hungarian scientist in his medical research and he presented the paper on utility of Low level lasers in medicine in 1969. This resulted in astounding discoveries -- laser beams relieved patients from pain, hastened recuperation, and drastically cut down marks and blemishes.
LLLT- The Science behind It
The photons, carriers of electromagnetic radiations, an inherent component of all wavelengths of light activate the multifunctional nucleotide, ATP. ATP (Adenosine Triphosphate) contain high energy phosphate bonds which transport energy to cells for biochemical processes including muscular contraction and enzymatic metabolism, thereby restoring the normal enzymatic balance and energy levels. This, in a radical but natural manner, accelerates the healing process.
LLLT is characterized by typical LASER attributes of coherence, polarization and monochromaticity. They are narrow and shiny beams which can penetrate and be easily assimilated by the body. Low level LASERs have a specific wavelength range. The frequency of light is given by the movement of light moving upward and downward.
How It Works
Low level laser therapy works in a similar manner to the photosynthesis in plants where the sun's energy is used by the plants which initiate crucial cellular processes hastening the cell production and rejuvenating processes of the plant cells.
In the similar way, the photons of LLT reach the human body. While the body can be compared to the plant, the low level laser light is similar to the sun light. Once absorbed, the LASER activates the cell metabolism and cell reconstruction. The Low Level Laser Therapy rays are capable of boring 3 inches deep into the body. These rays insert bio photons into the damaged and the living cells. These cells start producing ATP improving their function, strengthening the body resistance by producing collagen, enzymes thereby improving the synthesis of various hormones. These substances are basic for the healthy functioning of the body cells. Hence the tissues are healed and pain disappears.
With photons as the driving force, the Low Level Laser is the silent healer of wounds, pains and dermatological disorders. It is established beyond doubt that unlike other drug or therapy, Low Level Laser Therapy has no peripheral or undesirable secondary effect. A laser is critical in revitalizing the impaired or injured cells by improving the resistance or immunity. Low Level Laser Therapy will go a long way in medical history and it has come to a stay.

Welcome to the laser-therapy.us research tool. This tool is a searchable collection of technical publications, books, videos and other resources about the use of lasers for photobiomodulation. This tool includes almost the entire U.S. library of medicine research papers on LLLT, videos from Youtube associated with therapy lasers and the tables of contents from laser therapy books. This allows users to search for a keyword or condition and see resources about using lasers to treat that condition. All the resources include links to the original source so we are not making any statement about the use of lasers for treating non-FDA cleared application, we are simple summarizing what others have said. Where every possible, we have included a link to the orginal publication.
Here are some of our favorite queries:
This tool uses a broad match query so:
The results of the search are sorted based on 3 quality factors on a scale of 1 to 10 with 10 being the best score. Originally all the resources were given a 5-5-5 until they could be individually evaluated. These scores are purely opinion and are only used to simplify the rank of the results from more valuable to least valuable. This should not be considered a critique of any work. This system was created to help researchers (including ourselves) find the most usable resources for any cold laser therapy research. The resources are assigned values based on the following 3 factors:
Over the past few years of working with research, we found that a majority of the published resources are lacking in one of these three ranking factors.
The original goal of this research tool was to tie published resources to the protocols in the laser-therapy.us library. This connection allows users to trace each protocol back to a list of resources so the protocol can be researched and improved.
When many of the first research papers were published, the most power laser available for therapy were less than 100mW and many systems had to be pulsed to keep the laser from burning out too quickly. Today, system are available that will deliver up to 60,000mW of continuous output. Because of these power limitation, many early studies were limited to extremely low dosages by today’s standards. It takes a 50mW system 17 minutes to deliver 50 joules at the surface of the skin. If this was spread over a large area of damage or was treating a deeper problem, the actual dosages were much less than 1J/cm2. Today, we know that these dosages typically produce very little or no results.
About 80% of the resources in this database are in the near infrared wavelength. There is also some interest in the red wavelength (600 to 660nm) . Other wavelengths like blue, purple, and green have very little scientific research behind them and have not gotten much traction in the core therapy market with the exception of some fringe consumer products.
This research tool is free to use but we make no claims about the accuracy of the information. It is an aggregation of existing published resources and it is up to the user to determine if the source of the resources has any value. The information provided through this web site should not be used for diagnosing or treating a health problem or disease. If you have or suspect you may have a health problem, you should consult your local health care provider.
