What is low level laser therapy LLLT?-Cold laser treatment methods is a somewhat innovative technology when compared to the a great number of alternative therapies such as acupuncture (that’s been practiced since 8000-3500 B.C.), chiropractic (since 1895) as well as physical therapy. Just like the abacus evolved into the computer, a variety of alternative medicine practices are expanding to also include light therapy. More recent advancements in low-level lasers now make it possible for the average medical professional or individual to own cold laser equipment. Cold lasers are sometimes called Low Level Lasers (LLL) or soft lasers.

Cold Laser treatment offers a non-intrusive option to acupuncture and surgery. It additionally allows for a non-addicting treatment which usually eliminates the complications associated with long-term medication treatment programs. Cold lasers tend to be commonly utilized for treatment associated with: Acute and chronic joint pain, Tendon strains, Muscle strain, Soft tissue injuries, Tendonitis, Arthritis, Tennis elbow, Back soreness, Bursitis, Carpal Tunnel Syndrome, in addition to Fibromyalgia.

In general, cold lasers usually are implemented in 2 specific methods. One is in fact Targeting acupuncture trigger points (analogous to acupuncture however minus the needles) and the other is actually by using Wide coverage of deep tissue with laser photons in order to spark changes within the tissue.

The cold laser creates an impulse of light at a specific wave length (typically 905nm) which will diminishes reflection in addition to scattering but maximized absorption of the energy (in photons) at a desire depth.

Various conditions such as joint pain involve a deep penetration (4-5 inches) that can only be accomplished using a super-pulsed laser emitter. Many systems also contain other lower wavelengths in addition to lower-power emitters for treating shallow tissue (like the lymph system or even surface scars). In addition, red light diode with a wave length of 660 nm could be utilized to add energy to even shallower levels of tissues. It is definitely the over-all judgement that wavelengths less than 660 nanometers are usually very easily absorbed within the surface tissue and are not optimized pertaining to deep tissue healing.

The purpose of laser therapies is to provide light energy units via infrared laser radiation, referred to as photons, to damaged cells. It is the preference of industry experts is that photons absorbed by the cells by way of laser therapy stimulate the mitochondria to boost production of ATP. This specific biochemical increase in cell energy can be utilized to enhance live cells from a state connected with illness to a stable, healthy state.

About 4000 reports have actually been performed in recent years to actually validate the effectiveness regarding cold laser therapies. The following actually are some of the particular advantages connected with Cold Laser Therapies. The therapy is definitely simple to implement, very safe, non-toxic, non-invasive, zero side effects or discomfort, cost effective with regard to both the practitioner and patient, particularly effective in treating ailments (more than 90% efficacy), superior alternative to pain killers, reduces the need regarding surgery, and often will work synergistically along with other modalities such as Chiro, Acupuncture, as well as Rehabilitation.

At this time, lasers are employed substantially in the medical industry intended for everything from cosmetic surgery, eye surgery and also heart surgery. The particular ability to place merely the right amount of energy straight into a vital spot of the human body is a fantastic advancement throughout the medical field. Cold lasers are usually an essential addition to these various other established medical laser treatments and the recent development involving professional cold lasers suggests that low level laser therapy LLLT will probably be a rapidly growing non-invasive medical treatment option.

What is History of low level laser therapy?

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 therapy for back pain 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 therapy for back pain LLLT and CD and DVD writers
Class 4 – Surgical laser

low level laser therapy for back pain 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 therapy for back pain 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 therapy work?

Acute orthopedic conditions such as sprains , strains, post-surgical pain, a whiplash injury , muscular back pain, cervical or lumbar radiculopathy, tendinitis and chronic conditions such as osteoarthritis , rheumatoid arthritis, frozen shoulder, neck and back pain, epicondylitis, carpal tunnel syndrome, tendinopathy, fibromyalgia, plantar fasciitis, post tibial fracture surgery and chronic regional pain syndrome are amenable to low level laser therapy for back pain LLLT. Dental conditions producing pain such as orthodontic procedures, dentine hypersensitivity, and third molar surgery respond well to treatment with low level laser therapy for back pain LLLT. Neuropathic pain conditions can also be treated such as post herpetic neuralgia, trigeminal neuralgia , and diabetic neuropathy. Due to the wide spectrum of conditions one would surmise that multiple mechanisms can operate to achieve pain relief.

The peripheral nerve endings of nociceptors, consisting of the thinly myelinated A∂ and unmyelinated, slow-conducting C fibers, lie within the epidermis. This complex network transduces noxious stimuli into action potentials. Moreover these nerve endings are very superficial in nature and thus are easily within the penetration depths of the wavelengths used in low level laser therapy for back pain LLLT. The cell bodies of neurons lie within the dorsal nerve root ganglion, but the elongated cytoplasm (axons) of the neurons extends from the cell body to the bare nerve endings in the surface of the skin. The direct effect of low level laser therapy for back pain LLLT are initially at the level of the epidermal neural network, but the effects move to nerves in subcutaneous tissues, sympathetic ganglia, and the neuromuscular junctions within muscles and nerve trunks.

low level laser therapy for back pain LLLT applied with a sufficient level of intensity causes an inhibition of action potentials where there is an approximately 30% neural blockade within 10 to 20 minutes of application, and which is reversed within about 24 hours . The laser application to a peripheral nerve does have a cascade effect whereby there is suppressed synaptic activity in second order neurons so that cortical areas of the pain matrix would not be activated.

Adenosine triphosphate (ATP) is the source of energy for all cells, and in neurons this ATP is synthesized by mitochondria while they are located in the dorsal root ganglion. These mitochondria are then transported along the cytoskeleton of the nerve by a monorail system of molecular motors. low level laser therapy for back pain LLLT acts like an anesthetic agent, in that both low level laser therapy for back pain LLLT and anesthetics have been shown to temporally disrupt the cytoskeleton for a matter of hours as evidenced by formation of reversible varicosities or beading along the axons, which in turn cause mitochondria to “pile up” where the cytoskeleton is disrupted. The exact mechanism for this effect is unknown but it is not a thermal action. It has been shown that low level laser therapy for back pain LLLT at the correct dose decreases mitochondrial membrane potential (MMP) in DRG neurons and that ATP production is then reduced so perhaps the lack of ATP could be cause of this neural blockade. The most immediate effect of nociceptor blockade is pain relief which occurs in a few minutes and has been shown by the timed onset of a conduction blockade in somatosensory-evoked potentials (SSEPs). This inhibition of peripheral sensitization not only lowers the activation threshold of nerves but also decreases the release of pro inflammatory neuropeptides (i.e. substance P and CGRP). In persistent pain disorders this reduction of tonic input to activated nociceptors and their synaptic connections, leads to a long-term down-regulation of second-order neurons. The modulation of neurotransmitters is a further possible mechanism of pain relief, as serotonin and endorphin levels have been shown to increase in animal models and following laser treatment of myofascial pain in patients [81]. Thus low level laser therapy for back pain LLLT can have short, medium and long term effects. Fast acting pain relief occurs within minutes of application, which is a result of a neural blockade of the peripheral and sympathetic nerves and the release of neuromuscular contractions leading to in a reduction of muscle spasms.

In the medium term there is a decrease of local edema and a reduction of inflammation within hours to days. The action of low level laser therapy for back pain LLLT in reducing swelling and inflammation has been well established in animal models as well as in clinical trials. The numbers of inflammatory cells has been shown to be reduced in joints injected with protease, in collagen-induced rheumatoid arthritis, and in acute pulmonary inflammation . The expression levels of pro-inflammatory cytokines have been shown to be reduced by low level laser therapy for back pain LLLT in burn wounds, in muscle cryo lesions and in delayed type hypersensitivity. The long term effects of low level laser therapy for back pain LLLT occur within a week or two and can last for months and sometimes years as a result of improved tissue healing.

Review of Literature on Low-level Laser Therapy Benefits for Nonpharmacological Pain Control in Chronic Pain and Osteoarthritis.

Introduction • Low-level laser therapy (LLLT) is a form of light therapy that triggers biochemical changes within cells. Photons are absorbed by cellular photoreceptors, triggering chemical alterations and potential biochemical benefits to the human body. LLLT has been used in pain management for years and is also known as cold laser therapy, which uses low-frequency continuous laser of typically 600 to 1000 nm wavelength for pain reduction and healing stimulation. Many studies have demonstrated analgesic and anti-inflammatory effects provided by photobiomodulation in both experimental and clinical trials. Objective • The purpose of this research article was to present a summary of the possible pain management benefits of LLLT. Results • In cold laser therapy, coherent light of wavelength 600 to 1000 nm is applied to an area of concern with hope for photo-stimulating the tissues in a way that promotes and accelerates healing. This is evidenced by the similarity in absorption spectra between oxidized cytochrome c oxidase and action spectra from biological responses to light. LLLT, using the properties of coherent light, has been seen to produce pain relief and fibroblastic regeneration in clinical trials and laboratory experiments. LLLT has also been seen to significantly reduce pain in the acute setting; it is proposed that LLLT is able to reduce pain by lowering the level of biochemical markers and oxidative stress, and the formation of edema and hemorrhage. Many studies have demonstrated analgesic and anti-inflammatory effects provided by photobiomodulation in both experimental and clinical trials. Conclusion • Based on current research, the utilization of LLLT for pain management and osteoarthritic conditions may be a complementary strategy used in clinical practice to provide symptom management for patients suffering from osteoarthritis and chronic pain.
