What is Low Level Laser Therapy (low level laser therapy devices LLLT)?-A growing number of studies are demonstrating the therapeutic benefits of using Low Level Laser Therapy (low level laser therapy devices LLLT) for treating both acute injuries and chronic pain. The treatment uses a painless, non-invasive device that emits infrared or near infrared light in the form of low-level laser beams or light emitting diodes that penetrate the skin to stimulate cellular function.

Sports teams, military doctors and specialty pain clinics all use low level laser therapy devices LLLT to relieve pain and accelerate healing in a variety of circumstances. It has proven to be particularly effective for treating neck and low-back pain, pain from injured muscles and joints and pain related to osteoarthritis and rheumatoid arthritis. While the exact reason for low level laser therapy devices LLLT’s effectiveness is not yet known, researchers believe that three different factors may be responsible: reduction of inflammation, reduction in the conduction of painful nerve impulses and increase in ATP activity (the substance that fuels our cells).

More than 200 randomized controlled clinical trials have been performed on low level lasers. Dr. Roberta Chow and researchers at the Nerve Research Foundation of the Brain and Mind Research Institute at the University of Sydney performed a meta-analysis study on neck pain, which was published in The Lancet. The team studied 16 trials involving a total of 820 participating patients. Patients with acute neck pain were 70 percent more likely to experience pain relief from low level laser therapy devices LLLT than placebo, while chronic neck pain sufferers were four times more likely to experience a reduction in pain from low level laser therapy devices LLLT. The level of pain relief was found to be about 20 points on a scale from 1 to 100, with relief in seven of the studies lasting into the medium-term. Patients reported very mild, if any, side effects, which was comparable to the experience reported by participants in the placebo group.

Therapists of all types, including physicians, physical therapists and chiropractors are increasingly using low level laser therapy devices LLLT as a complementary therapy in their practices due to its effectiveness. As the researchers write, the results of their study show that “low level laser therapy devices LLLT reduces pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients with chronic neck pain.”

“Whatever the mechanism of action, clinical benefits of low level laser therapy devices LLLT occur both when low level laser therapy devices LLLT is used as monotherapy and in the context of a regular exercise and stretching program,” the researchers added. “In clinical settings, combination with an exercise program is probably preferable. The results of low level laser therapy devices LLLT in this review compare favorably with other widely used therapies, and especially with pharmacological interventions, for which evidence is sparse and side-effects are common.”

How low level laser therapy devices work?

How low level laser therapy devices LLLT Works?-There are three phases of hair growth: the anagen phase, which is the growth stage; the catagen stage, which is the transition stage where hair follicles begin to shrink; and the telogen phase, where hair follicles become dormant and shed. The stimulation from low level laser therapy devices LLLT helps to shift hair follicles into the anagen phase (and therefore restore hair growth), in multiple ways.

low level laser therapy devices LLLT uses a light that produces a specific wavelength (typically in the range of 630 to 670 nanometers) which has a unique ability to be absorbed by the molecules of the hair follicles. This type of light penetrates the scalp and stimulates the epidermal stem cells which are responsible for the regeneration of hair follicles. The increased blood flow that low level laser therapy devices LLLT causes helps to increase the delivery of nutrients and oxygen to the hair follicles. low level laser therapy devices LLLT stimulates metabolic processes necessary for hair growth and helps to prevent the build-up of DHT in the follicles.

How low level laser therapy devices 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 devices 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 devices 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 devices 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 devices LLLT. The most important of these signaling molecules are thought to be ATP, cyclic-AMP, NO and ROS .

low level laser therapy devices 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 devices 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 devices 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.

Why low level laser therapy devices?

What and why are the advantages of LLLT?-The Erchonia laser has been found to offer superior healing and pain relieving effects. The results seem equally untouchable for early stages of acute injuries, and for chronic problems. LLLT is a universal method of treating mucles, ligament, tendon, connective tissue, bone, neurological dysfunction or damage and skin tissue. When the laser is applied with chiropractic care the best results are achieved to organize the nervous system and promote healing. Erchonia laser therapy is a major advantage for athletes due to the neurological applications and extremely fast results that can be achieved.

What is low level laser therapy Contraindications?

Cold laser therapy should not be used over any suspicious cancerous lesions, or carcinoma, over the thyroid, on pregnant patients, and there should not be direct irradiation of the eyes, as the laser can cause permanent damage to the eyes.

Pregnant women are recommended not to undergo the procedure, since its effects on unborn children are not yet known. The doctor and the patient should use protective eyeglasses so that there is no direct eye exposure.
