The lasers used in low level laser therapy lllt are typically small (often handheld) units, and unlike surgical and aesthetic lasers, do not heat the targeted tissue. Instead, low level laser therapy lllt emits low levels of light that are absorbed by your mitochondria (the energy-producing organelles in many of your cells), which then can increase cellular energy production and ultimately help heal surrounding tissue. This process is comparable to plant photosynthesis, during which sunlight is absorbed by plants and converted to energy for the plants to grow.

Low level laser therapy is a form of alternative medicine that uses laser light at low levels or near-infrared light. The light is applied to the surface skin of the body with the intentions of decreasing pain or inflammation, promoting healing of wounds, tissues, and nerves, or for preventing tissue damage. This is much different than the high level lasers that we know for surgical procedures to cut and destroy unhealthy tissue.

Laser in an acronym for Light Amplification by the Simulated Emission of Radiation. Lasers emit coherent and direct light that can target specific processes in the body. Low Level Laser, also known as cold laser does not radiate heat in the tissue and the depth of penetration is determined by its specific wavelength. Due to these unique properties Low Level Laser Therapy (low level laser therapy lllt) has been widely researched and used since the 1960’s. Today low level laser therapy lllt is used in wound healing clinics, allied health professional clinics and medical centres throughout the western world.

Low Level Lasers have shown to:

Bio-modulate processes in the tissue.
Increase ATP production in the mitochondria.
Stimulate lymph fluid movement and the removal of cellular debris.
Give a natural analgesic effect.
Temporarily increase vasodilation to assist in blood flow to the affected area.
Reduction in fibrous tissue formation.

What is Low Level Laser Therapy?

Low level laser therapy, also known as phototherapy or cold laser, uses low intensity lasers and light emitting diodes (LEDs) at the infrared and visible red wavelengths to relieve pain and reduce inflammation caused by damaged tissue.

Low level laser therapy (low level laser therapy lllt) is not a newly-discovered treatment. It was pioneered in the 1960s and there are thousands of published studies documenting its effects in a range of medical and veterinary applications. Health professionals around the world use low level laser therapy to treat patients suffering from a range of pain conditions.
Low Level Laser Therapy can assist to

relieve muscle and joint pain
speed healing
reduce swelling
promote relaxation of muscles to alleviate spasms
improve functionality and mobility
relieve stiffness

The low level laser light particles, known as photons, penetrate into the tissue through the skin to a specific depth depending on the wavelength. Typically, low level laser devices use 600nm-1000nm (visible red-infrared) wavelengths.

Unlike surgical lasers, the intensity of low level laser is not high enough to produce heat, so it cannot burn or heat the skin.

The Handy Pulse Laser is an low level laser therapy lllt laser which combines low-level pulse laser infrared radiation, pulsating LED infrared radiation, visible LED red light, and a static magnetic field.

How Low-Level Laser Therapy works

low level laser therapy lllt is also known as Cold Laser Therapy. 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 low level laser therapy lllt from PMR patients in social media.

How low level laser therapy lllt work?

For low-power visible or near-infrared light to have an effect on a biologic system, the photon must be absorbed by electronic absorption bands belonging to a photon acceptor or chromophore (first law of photobiology) . A chromophore is a molecule (or portion of a molecule) which imparts a color to a compound (e.g. chlorophyll, hemoglobin, myoglobin, cytochrome c oxidase, other cytochromes, flavin, flavoproteins or porphyrins) . The “optical window” in a tissue describes a range of wavelengths where the penetration of light into tissue is maximized by employing red and near-infrared wavelengths . The optimum wavelength has been estimated to be around 810 nm. Mitochondria are “the cellular power plants” in our cells and as such they convert food molecules and oxygen into energy (ATP) by oxidative phosphorylation. It has been proposed that cytochrome c oxidase (COX) is the primary photo-acceptor for the red-NIR wavelength range in mammalian cells . Nitric oxide (NO) produced in mitochondria can inhibit respiration by binding to COX and displace oxygen especially in injured or hypoxic cells . It is proposed that low level laser therapy lllt can photo-dissociate NO from COX and reverse the mitochondrial inhibition of respiration due to excessive NO binding . The process of light mediated vasodilation was first described by RF Furchgott in 1968, and his research on the biological properties of nitric oxide eventually led to the award of a Nobel Prize in 1998 . low level laser therapy lllt is able to produce a shift in the overall cell redox potential in the direction of greater oxidation by increasing reactive oxygen species (ROS) and decreasing reactive nitrogen species (RNS). The long-term effects of low level laser therapy lllt are thought to be due to the activation of various transcription factors by the immediate chemical signaling molecules produce from mitochondrial stimulation by low level laser therapy lllt. The most important of these signaling molecules are thought to be ATP, cyclic-AMP, NO and ROS .

low level laser therapy lllt at low doses has been shown to enhance cell proliferation of fibroblasts , keratinocytes, endothelial cells and lymphocytes . The mechanism of proliferation is thought to result from photo-stimulation of the mitochondria leading to activation of signaling pathways and up regulation of transcription factors eventually giving rise to increases in growth factors . low level laser therapy lllt can enhance neovascularization, promote angiogenesis and increase collagen synthesis to aid in the healing of acute and chronic wounds . It has been observed in many studies, that low level laser therapy lllt exhibits a biphasic dose response curve, where by lower doses of light are more effective than much higher doses. These low doses of light have demonstrated the ability to heal skin, nerves, tendons, cartilage and bones.
