What is Low level laser treatment LLLT ?-Low level laser therapy is a treatment procedure that makes use of certain specific wavelengths of light to interact and communicate with tissues, accelerating the healing process inside human body.
Low Level Laser Therapy

Applied by a special laser beam generator, the part of the body that requires healing is exposed to low intensity laser, consequently producing photon energy. Eventually, this energy gets transformed into bio-mechanical energy which allows the restoration of normal functioning of cells. This therapy has gained momentum due to its striking attributes like alleviation of pain, inflammation, and initiate healing process on the affected cells.

Just like photosynthesis works plants, Low level laser treatment LLLT also has a photo-chemical effects on the body. This mechanism of action occurs inside Mitochondria. The desired effect is dependent on the application of correct wavelength and density of light for a decent amount of time, somewhere between 30 to 60 seconds. The pulses generated can improve tissue repair and anti-inflammatory effects as well.

In addition, it is used on patients who suffer from a variety of health conditions and ailments to help them do away with pain, swelling, reduce spasms and increase functionality.

Low level laser treatment LLLT (Low Level Laser Therapy) is the application of red and near infra-red light over injuries or lesions to improve wound and soft tissue healing, reduce inflammation and give relief for both acute and chronic pain. First developed in 1967, it is now commonly referred to as Low level laser treatment LLLT.

Low level laser treatment LLLT is used to: increase the speed, quality and tensile strength of tissue repair; resolve inflammation and relieve pain (analgesia).

The red and near infrared light (600nm-1000nm) commonly used in Low level laser treatment LLLT can be produced by laser or high intensity LEDs. The intensity of Low level laser treatment LLLT lasers and LED’s is not high like a surgical laser. There is no heating effect.

The effects of Low level laser treatment LLLT are photochemical (like photosynthesis in plants). When the correct intensity and treatment times are used, red and near infrared light reduces oxidative stress and increases ATP. This improves cell metabolism and reduce inflammation. These effects can be enhanced with pulses however when analgesia is required there is a second mechanism which works best when a strong continuous beam is applied.

Low level laser treatment LLLT devices are typically delivering 10mW – 500mW (0.01 -> 0.01 Watts). The power density typically ranges from 0.005W/Cm² -> 5 W/Cm².

Low level laser treatment LLLT is popularly used for soft tissue injuries, joint conditions, neuropathic pain, non-healing leg and pressure ulcers.

Download ‘Low level laser treatment LLLT dose review (PDF)’
This paper from Harvard Medical School reviews the Low level laser treatment LLLT mechanisms and the biphasic dose response. It summarises the molecular and cellular mechanisms of Low level laser treatment LLLT, gives a scientific explanation for the biphasic dose response (why a low dose has a stimulatory effect and why a high dose inhibits). Low power densities tend to get better healing and anti-inflammatory effects where higher power densities are more likely to inhibit (which may be useful if you just want an analgesic effect). I have to disclose an interest in this paper because I am a co-author. James Carroll CEO THOR Photomedicine.

What is History of Low level laser treatment LLLT?

In 1903, Dr. Nils Finsen was awarded a Nobel Prize for his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation . In 1960, Professor Maiman TH built the first working red ruby laser , but it was not until 1967 when Mester E et al. was able to demonstrate the phenomenon of “laser bio stimulation” . In 1999, Whelan H et al. presented his work on the medical applications of light emitting diodes (LED) for use on the NASA space station . Subsequently over 400 Phase III randomized, double-blind, placebo-controlled trials have been published, with over 4000 laboratory studies of Low level laser treatment LLLT. (Pubmed.gov)

A laser is a device that generates light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. There are four main classes of lasers as defined by the International Engineering Consortium (IEC standard 60825.) These classes indicate potential danger the radiation is to the eye.

Class 1/1M – CD player
Class 2/2M – laser pointer
Class 3R/3B – Low level laser treatment LLLT and CD and DVD writers
Class 4 – Surgical laser

Low level laser treatment LLLT is the application of light (usually a low powered laser or LED typically power range of (10mW–500mW). Light with a wavelength in the red to near infrared region of the spectrum (660nm–905nm), is generally employed because these wavelengths have the ability to penetrate skin, and soft/hard tissues (Figure 2) and are proven in clinical trials to have a good effect on pain, inflammation and tissue repair. The power density (irradiance) is usually between 5W/cm2 and is applied to an injury or to a painful site for 30–60 seconds a few times a week for several weeks. The result is a reduction of inflammation, pain relief and accelerated tissue regeneration. In most cases the lasers/LEDs used for Low level laser treatment LLLT emit a divergent beam (not focused or collimated) because collimation is lost in tissue, but as a consequence ocular risks are also diminished over distance.

How low level laser treatment device  work?

How Low level laser treatment LLLT works-LLLT is also known as Low level laser treatment LLLT. It uses laser light placed exactly over the area with pain. The device which is only flashlight size emits specific wavelengths of light to penetrate about 2 to 5 cm through the layers of the skin. A wavelength power of 830 or 940 nm has been reported to have a moderate effect on pain. But the studies are not completely conclusive as efficacy may depend on several other factors.

Class 3B for LLT

Not all types of lasers can be used to help chronic pain relief. The Food & Drugs Administration (FDA) classified medical laser treatment into 3 types: Class 4 Surgical Lasers, Class 3B Non-surgical Lasers, and Class 3A Low-Level Lasers. Class 3B and Class 3A are used in non-invasive treatments. In relation to chronic pain treatment, only Class 3B is able to penetrate and help in the healing process of deep tissue and joint pains.

Self-healing of the body

This laser therapy stimulates all types of cells.There are about 200 cell types in our body including the musculoskeletal cell system which is responsible for our movements and body support. When laser lights are directed to the pain areas, the muscle cells will start to heal and pain will be reduced. According to studies, a number of conditions merited from low laser treatment. It can be an alternative cure for rheumatoid arthritis, carpal tunnel syndrome, fibromyalgia, back pain, knee pain, tendonitis, neck pain and others. The first three diseases mentioned are autoimmune diseases just like polymyalgia rheumatica. There have also been testimonies and positive feedback about LLLT from PMR patients in social media.

Why low level laser treatment device ?

What is Low level laser treatment LLLT used for?-Low level laser treatment LLLT is used to increase the speed, quality and tensile strength of tissue repair, resolve inflammation, and give pain relief.

It is an attractive form of treatment for animal athletes, due to the prospect of shorter recovery and lay-off times.

The portability of battery-powered diode laser systems enables treatment to be carried out in the barn, the trailer, or in the field, allowing the immediate and therefore more effective treatment of equine sports injuries, such as muscle tears, haematomas, and tendinopathies.

About Laser Therapy-A huge amount of research data has been collected on the effects of laser therapy both in laboratory and clinical settings. The most significant results include:

Wound healing is significantly improved by Low Level Laser Therapy (Low level laser treatment LLLT), even in non-healing wounds, thought to be due to the increased level of collagen brought about by laser treatment. Collagen, the chief constituent of connective tissue, is recognized as the most important ingredient in wound healing.
Increases in blood flow by means of capillary and arterial widening of the lumen of blood vessels, vasodilatation.
Marked improvement in re-establishment of the lymphatic system after trauma, resulting in reduction of swelling. This is due to the evacuation of dirty proteins by the regenerated lymphatic vessels.
Laser light stimulates release of the body’s own pain killing chemicals such as endorphins and enkephalins, facilitating natural, long lasting pain relief
