Low-Level Laser Therapy (LLLT), also known as cold laser therapy, uses specific wavelengths of light to treat injuries and lesions. This therapy promotes healing by increasing the speed, quality, and strength of tissue repair, reducing inflammation, enhancing range of motion, and providing pain relief.

Research has shown that the cells of your body actually communicate with each other through coherent light (laser). With the Erchonia Medical laser there are specific

pulsations (hertz) that can be programmed with the laser frequency allowing the practitioner to talk “cell talk” with the body. Specific pulsations have been shown to

create different physiological responses of the cell. This is extremely important when working with a variety of injury and disease conditions to promote healing. The

metabolism of injured and diseased tissue is decreased and the laser creates an increase in metabolism and cell communication immediately.

The laser accelerates cellular reproduction and growth.

• Faster wound healing. The laser stimulates fibroblast development in damaged tissue. The reduction in recovery time is an important consideration.

• Increased metabolic activity. Helps the body increase output of specific enzymes, greater oxygen to blood cells and more effective immune response are induced by laser.

• Reduced fibrous tissue formation. The laser reduces the formation of scar tissue following tissue damage from cuts, scratches, burns, or following surgery.

• Anti-inflammatory action. The laser reduces swelling caused by bruising or inflammation of joints to give improved joint mobility.

• Increased vascular activity. The laser stimulates lymph and blood circulation, to allow the affected tissue to have the best possible circulation.

• Stimulated nerve function. Slow recovery of nerve function in damaged tissue can result in "dead" limbs or numb areas. Laser will speed the process of nerve cell reconnection to bring the numb areas back to life. Laser also increases the amplitude of action potentials to optimize muscle action.

The Erchonia Laser has been found to offer superior healing and pain relieving effects when compared to other electrotherapeutic modalities. The results seem equally untouchable for early stages of acute injuries, and for chronic problems.

When combined with other therapies, the benefits seem to amplify one another.

What is cold laser?

The process of low-level laser therapy is within the visible light spectrum of 380–700nm. In order to achieve maximum photobiological effects, Erchonia (class II lasers) adheres to the following delivery fundamentals: Laser light has an output under 500mw. It is a non-thermal process for adjunctive use in pain therapy. “LLLT delivered at low doses tends to work better than the same wavelength delivered at high levels, which illustrates the basic concept of biphasic dose response or hormesis” (Calabrese 2001b) Fundamentals of Photochemistry

What are LEDs (Light Emitting Diodes)?

LEDs cannot achieve the same narrow band of wavelength, instead, LEDs produce light that is disorganized or incoherent. Laser light is dramatically more effective in producing photochemical effects than LED. This is evident in over a dozen, double-blind, placebo-controlled clinical trials using Erchonia lasers where test subjects established both statistical significance and clinically meaningful results over the placebo group which received LED treatment.

What is a Class IV laser?

Devices with a laser output above 500mw are not LLLT (Low-Level Laser Therapy). Instead, they are classified as High Intensity Laser (HIL) or Class 4 Lasers. These devices are intended to “provide topical heating for the purpose of elevating tissue temperature for temporary relief of muscle and joint pain and stiffness, arthritis pain, or muscle spasm, the temporary increase in local blood circulation and/or promoting relaxation of muscle”.

​

What is Infrared light?

Another type of electromagnetic radiation is infrared (IR) which includes wavelengths higher than 780nm. The infrared light spectrum exhibits strong absorption from vibrations of the water molecule. The result of infrared absorption is heating of the tissue since it increases molecular vibrational activity. Simply, while visible light can produce photochemical effects, infrared only produces molecular rotations and vibrations

There is a common misconception, often propagated by the manufacturers of Class 4 Lasers, that high power with longer wavelengths results in:

• Deeper penetration, allowing for the treatment of a wider range of conditions.

• More efficacious results, due to the delivery of more energy into the cells.

Well-documented reasons why it is not correct:

1. Laser light with wavelengths exceeding 950nm is highly absorbed by water, preventing much of its energy from penetrating the dermis. This strong absorption can also cause localized heating, leading to discomfort or pain, which may restrict its therapeutic application.

2. There is an optimal ‘dose’ of laser energy (typically 2-4 joules / cm²) required for therapeutic biostimulation. Deviating from this dose, either by providing significantly less or more energy, can be counterproductive. HLLT devices, with their substantial power outputs, risk surpassing this optimal range.

3. It is theorized that a minimum energy of 1.7eV per photon is required for therapeutic biostimulation via photochemical means – wavelengths exceeding 730nm cannot deliver this 1.7eV. As a result, HLLT devices, which often operate within these longer wavelengths, may not primarily function through inducing photochemical reactions. Instead, they might rely on alternative mechanisms, such as the therapeutic influence of localized heat generation. However, this approach may be less efficacious compared to biostimulation by photochemistry.

Low-Level Laser Therapy devices, on the other hand, aim to deliver energy via low-output, short-wavelength beams of light. The general theory is that this approach transfers the optimal amount of energy for stimulating and enhancing cell function, while not damaging cells or producing painful heat sensations. Within the LLLT sector, however, some of the higher output devices still generate heat/pain. Furthermore, many devices are advertised as ‘lasers’, when in fact they are Light Emitting Diodes (LEDs) or Superluminescent Diodes (SLDs). In contrast to LEDs or SLDs, ‘true’ lasers generate monochromatic, collimated, and coherent beams of light. These three properties of true lasers make them the most effective and efficient devices within the Laser Therapy sector. To separate Erchonia® from such technologies, and from HLLT more generally, we say that Erchonia® lasers are ‘non-thermal, true lasers’. Our lasers do not produce any heat or painful sensations and are monochromatic, collimated, and coherent.

The Erchonia Corporation has received 22 FDA 510(k) market clearances for its patented laser systems:

• Chronic low back pain The FX 635 laser received FDA clearance in May 2018 for treating chronic low back pain. The clearance was based on a clinical trial where 72% of patients met the success criteria of a minimum 30% decrease in pain.

• Whole body pain The FX 635 laser also received FDA clearance for treating chronic musculoskeletal pain throughout the body. The clearance was based on a randomized, placebo-controlled trial where patients who received the laser therapy had a 49% reduction in pain.

• Autism Erchonia has submitted data to the FDA for a low-level laser therapy for children and adolescents with autism. The study found that the laser therapy was safe and effective, and more effective than a placebo device.

• Other clearances Erchonia has also received FDA clearances for the Erchonia EVRL and the Erchonia PL2000.

Erchonia is a company that specializes in low-level laser technology for use by physicians, chiropractors, physical therapists, health clinics, and veterinarians.

Low level laser therapy has is very safe; the only general precaution is the use of special filtering glasses when a class 3B laser is in use.

No. There are no side effects; no pain, discomfort or recovery time of any kind. It is completely non-invasive.

Most patients will feel no heat or any sensation from the laser. A few may describe a light sensation as though being lightly touched with a feather.

Results vary from patient to patient but could begin to appear even after the first treatment. Still, findings support a treatment plan consisting of 10 treatments for best results.

Low-level laser therapy (LLLT) uses low-intensity photonic energy to treat various conditions. This therapy excites the body's cells, infusing them with energy. The primary benefits include reducing inflammation, enhancing cell function, and increasing blood flow.
