What is laser therapy?
L.A.S.E.R. (Light Amplification by Stimulated Emission of Radiation) is a name for a type of intense radiation of the light spectrum. A laser is a beam of light in which high energies can be concentrated. Laser light has unique physical properties, which other types of light do not have. These are coherence and monochromaticity. These are what makes laser light is so effective compared to other kinds of light in the field of pain reduction and healing. Laser therapy (also known as phototherapy and low level laser therapy) involves the application of low power coherent light to injuries and lesions to stimulate healing and reduce pain. It is used to increase the speed, quality and strength of tissue repair, resolve inflammation and give pain relief. Laser therapy has been found to offer superior healing and pain relieving effects compared to other electrotherapeutic modalities such as ultrasound, especially in dealing with chronic problems and in the early stages of acute injuries. Laser therapy is a complete system of treating muscle, tendon, ligament, connective tissue, bone, nerve, and dermal tissues in a non-invasive, drug-free modality.
Worldwide, laser therapy has been embraced to provide accelerated pain relief and healing. For over 20 years, clinicians found that laser therapy treats a variety of conditions including:
- Acute and chronic pain
- Back pain
- Carpal Tunnel
- Ligament sprains
- Muscle strain
- Soft tissue injuries
- Tennis elbow
Proven technology Numerous randomized double blind clinical trials have shown the efficacy of the TerraQuant on various health conditions. Over 4000 studies have been conducted to validate the effectiveness of laser therapy.
Multi Radiance Medical laser therapy devices provide deep tissue penetration with maximum photonic density. These FDA-cleared devices have more power than most class IV lasers with the safety of class II.
Multiple therapeutic radiances synergistically work together for an optimal biological response at the cellular level. A unique combination of these radiances creates the perfect environment for optimal pain relief and accelerated healing.
The foundation of Multi Radiance Technology™
1. Super Pulsed Laser (905nm) produces a high power level of impulse light at a billionth of a second. It is the high power during each pulse that drives the photons, or light energy, to the target tissue, up to 10—13cm (4—5 inches) deep.
The TerraQuant's high peak power of up to 25,000mW creates a higher photon density, delivering the highest concentration of photons for healing and providing the deepest tissue penetration. Super pulsed laser strongly influences pain reduction, the improvement of microcirculation and increases cell metabolism in the form of ATP production.
2. Pulsed Broad Band Infrared Emitting Diodes (875nm) penetrate shallower tissue depths than the laser but provide an overall broader spectrum, when compared to laser radiation, by gently heating the surface tissue layer.
3. Pulsed Red Light (660nm) penetrates shallower tissue depth and has beneficial anti-inflammatory effects.
4. Static Magnetic Field keeps ionized molecules of tissue in a dissociated stage, enhancing the energy potential at the molecular and cellular levels.
Healing with Light at the Cellular Level
The goal of laser therapy is to deliver light energy units from infrared laser radiation, called photons, to damaged cells. The consensus of experts is that photons absorbed by the cells through laser therapy stimuate the mitochondria to accelerate production of ATP. This biochemical increase in cell energy is used to transform live cells from a state of illness to a stable, healthy state.
Therapeutic Laser Biological Effects
- Rapid Cell Growth — Laser light accelerates cellular reproduction and growth.
- Faster Wound Healing — Laser light stimulates fibroblast development and accelerates collagen synthesis in damaged tissue.
- Increased Metabolic Activity — Higher outputs of specific enzymes, greater oxygen and food particle loads for blood cells and thus greater production of the basic food source for cells, Adenosine Tri-Phosphate (ATP).
- Reduced Fibrous Tissue Formation — Laser light reduces the formation of scar tissue following tissue damage from: cuts, scratches, burns or post surgery.
- Anti-Inflammatory Action — Laser light reduces swelling caused by bruising or inflammation of joints to give enhanced joint mobility.
- Increased Vascular Activity — Laser light induces temporary vasodilation increasing blood flow to damaged areas.
- Stimulated Nerve Function — Slow recovery of nerve function in damaged tissue can result in “dead” limbs or numb areas. Laser light speeds the process of nerve cell reconnection to bring the numb areas back to life.
Super Pulsed Infrared Laser (905 nm) is the essential component of Multi Radiance Technology™. Multi Radiance Medical’s super pulsed laser is the fastest in the world, delivering a pulse at billionths of a second. Combined with 25,000 mW or 50,000 mW of peak power, the result is a higher concentration of light energy, or photons, driven deeper into the target tissue, without the risk of burning the tissue.
Super pulsing allows for deeper penetration than a laser of the same wavelength that is not super pulsed but has the same average output power. This is because ultimately short pulses allow for quick absorption at the cellular level. And the period between pulses promotes a better environment for enhanced cell communication, leading to an optimum pain relief and accelerated healing.
When comparing technology, some laser devices may offer pulsed mode. Do not confuse them with super pulsed lasers. Unlike super pulsed lasers, pulsed lasers are created by “chopping the beam”-mechanically turning the laser on and off, much like duty cycle. Their depth is limited in comparison to super pulsed technology due to the decreased power created by the duty cycle of the device.
Advantages of Super Pulsed Laser:
1. More Power = More Photonic Energy
Advanced Semi-Conductor laser diode delivers higher power pulses of Photonic Energy in thousands of milliwatts without burning tissue
2. Increases in peak power improve depth penetration of energy into tissue
3. Breakthrough in Thermal Barrier
Super Pulsed Laser produces a high peak impulse of intense light for a fraction of a second. Thus, there are no damaging thermal effects in the tissue because the pulses are of very short duration.
4. Maximum Photonic Density
The power density during these very high pulses yields an extremely high photon flux and saturation, further delivering a stronger therapeutic effect into the tissue.
The Super Pulsed Laser Technology provides more energy and penetrates deeper than comparable non-super pulsed lasers but does not generate excessive damaging heat.

How does it work?.
The effects of laser therapy are photochemical. Photons enter the tissue and are absorbed in the cell’s mitochondria and at the cell membrane by chromophores. These chromophores are photosensitizers that generate reactive oxygen species following irradiation thereby influencing cellular redox states and the mitochondrial respiratory chain. Within the mitochondria, the photonic energy is converted to electromagnetic energy in the form of molecular bonds in ATP (Adenosine Triphosphate). In order to interact with the living cell, laser light has to be absorbed by intracellular chromophores. Cell membrane permeability increases, which causes physiological changes to occur. These physiological changes affect macrophages, fibroblasts, endothelial cells, mast cells, bradykinin and nerve conduction rates. The clinical and physiological effects are obtained by the way in which tissues absorb laser radiation. This tissue absorption depends on the wavelength of the beam itself and the power to ensure that the laser energy reaches the target tissue at the necessary clinical levels. The improper wavelength of laser light would not penetrate into the tissue to reach the target area. Furthermore, even if one has a laser with the proper wavelength, if the device does not have enough power to drive the energy into the tissue, the target area may not realize the potential benefits. Each type of laser emits light at a very specific wavelength which interacts with the irradiated tissue. It also acts in particular with the chromophores present in the tissue, but in a different way. A chromophore, intrinsic or extrinsic, is any substance, colored or clear, which is able to absorb radiation. Among the endogenous chromophores are water and hemoglobin, nucleic acid and proteins. Among the exogenic chromophores are porphyrins and hematoporphyrins, which are injected into the organism. These are described as photosensitizers because they fix themselves to the tissue making it photosensitive at specific wavelengths.
How deep into the tissue can laser light penetrate?
The level of tissue penetration by the laser beam depends on the beam’s optical characteristics, as well as on the concentration and depth of the chromophores, which are absorbed at different percentages according to the laser light’s wavelength. For instance, water absorbs almost 100 percent of the laser irradiation at 10,600 nanometers, the wavelength of a CO2 gas laser. That is the reason why this type of laser wavelength is used in surgical applications. Other factors affecting the depth of penetration are the technical design of the laser device and the particular treatment technique used. There is no exact limit with respect to the depth penetrated by the light. The laser light gets weaker the further from the surface it penetrates where eventually the light intensity is so low that no biological effect from it can be measured. In addition to the factors mentioned, the depth of penetration is also contingent on tissue type, pigmentation and foreign substances on the skin surface such as creams or applied oils. Bone, muscles and other soft tissues are transparent to certain laser lights, which means that light can safely penetrate these tissues. The radiation in the visible spectrum, between 400 and 600 nanometers, is absorbed by the melanin, while the whole extension of the visible which goes from 420 to 750 nanometers is absorbed by composite tetrapyrrolics. In the infrared, which covers about 10,000 nanometers of light spectrum, water is the main chromophore. Fortunately, there exists a narrow band in the light spectrum where water is not a highly efficient chromophore, thereby allowing light energy to penetrate tissue that is rich in water content. This narrow band, which extends approximately from 600 to 1,200 nanometers, is the so-called “therapeutic window”. That is the reason why the lasers in the market today have wavelengths within the 600-1,200 nanometer limit. The penetration index is not at the same level throughout the therapeutic window. In fact, lasers in the 600 to 730 nanometer range have less penetration and are more suitable for superficial applications such as in acupuncture methodologies.
Lasers vs. LED?
Light emitting diodes (LED) are tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they do not have a filament that will burn out. They are illuminated solely by the movement of electrons in a semiconductor material. LED’s produce incoherent light just like an ordinary light bulb. Light from LED’s have very little tissue penetration compared to laser light. By applying the first law of photochemistry (Grotthus-Draper Law) which states that light must be absorbed by a molecule before photochemistry can occur, one can immediately conclude that light from LED’s will work only on skin level conditions. For conditions deeper than skin layers, one must choose laser.
Pulsed vs. continuous wave lasers?
In general, laser diodes are either continuous wave or pulsed. The continuous wave (CW) diodes emit laser energy continuously, hence its name. Pulsed diodes emit a radiation impulse with a high amplitude (intensity) and duration which is typically extremely short: 100-200 nanoseconds. Continuous wave lasers produce a fixed level of power during emission. Although lacking the high peak power of a "true" or "super" pulsed laser, most continuous wave lasers can be made to flash a number of times per second to simulate pulse-like rhythms by interrupting the flow of light rapidly as in turning a light switch “off” and “on”. “True” or “super” pulsed lasers, as the name implies, produce a brief high power level light impulse. It is the high power level achieved during each pulse that drives the light energy to the target tissue. Even though the pulse peaks at a high power level there are no deleterious thermal effects in the tissue because the pulses are of such short duration. Therefore, the peak power of a “true” or “super” pulsed laser is quite high compared to its average pulse power. By using “true” or “super” pulsed lasers, one is able to more effectively drive light energy into tissue. The laser and electronic technologies required to use pulsed diodes are more advanced and the diodes themselves are more expensive than the continuous wave diodes. This is why over 90% of the therapeutic lasers in the North American market are low power continuous wave lasers. Some of these lasers provide power literally at the same level as an inexpensive laser pointer costing around $30.
Is laser therapy safe?
Yes. Laser therapy is a drug-free, non invasive therapy with superior healing ability. However, since lasers produce a high intensity light, one should never shine the laser directly into the eye. Further it is recommended that the laser device not be used directly on any neoplasmic tissue. Pregnant women should refrain from laser therapy applied directly to the abdomen. Also people with pacemakers should not use laser therapy near the heart.
Is laser therapy scientifically well documented?
There are more than 120 double-blind positive studies confirming the clinical effects of laser therapy. More than 300 research reports have been published. There are over 300 dental studies alone. More than 90% of these studies verify the clinical value of laser therapy. A review of negative results shows that low dosage was the single most significant factor. By dosage is meant the light energy delivered to a given unit area during treatment. The energy is measured in joules and the area in cm2. Assuming that the power of the laser remains constant during the treatment, the energy of the light will be equal to the power in watts multiplied by the time in seconds during which the light is emitted. Therefore, a laser with more power (watts) can deliver the same amount of energy (joules) in less time. A pulsed laser with more average power (watts) can deliver the same amount of energy (joules) in less time and at deeper target tissues than a continuous wave laser.
What is pulsed electromagnetic therapy?
Magnetic fields play a key role in biological life. A magnetic field is created when a conductor is crossed by an electrical current. Magnetic fields arranged around single conductors are summed in a coil producing a density of magnetic force lines. If current produced in this way flows in pulses, then a pulsed magnetic field is created. In the bioenergetic and chemical terms of an organism, the essential concept of magnetism is not the magnetic load, but the energy-rich dipole which is surrounded by a magnetic field and whose transformation and exploitation for the production of energy in the organism is highly significant. The most important effect from pulsed electromagnetic fields (EMF) therapy is found on the cellular transmembrane potential (TMP). It is known that damaged or diseased cells present an abnormally low TMP, up to 80% lower than healthy cells. This signifies a reduced metabolism, impairment of the electrogenic sodium-potassium (Na-K) pump activity, and therefore, reduced ATP production. In a nutshell, the TMP is proportional to the activity of the Na-K pump and thus to the rate of healing. Healthy cells have TMP voltages of 70 to 100 millivolts. Due to constant stresses of modern life and a toxic environment, cell voltages tend to drop as we age or due to illness. As the voltage drops, the cell is unable to maintain a healthy environment for itself. If the electrical charge of a cell drops to 50, the patient may experience chronic fatigue. Electromagnetic therapy with the Maxi provides one effective way to affect healing rates by increasing cellular TMP.
Does super pulsed laser therapy cause heat damage or cancer in the tissue?
Absolutely not. The average power and the type of light source (non-ionizing) laser therapy uses do not permit heat-damage or carcinogenic (cancer-causing) effects. Due to increased blood circulation there is sometimes a very minimal sensation of warmth locally.
