Laser Therapy


Laser acupuncture is the synthesis of the ancient treasure trove of Acupuncture and phototherapy (therapy with light). Acupuncture and phototherapy are both traditions that are thousands of years old. Both have changed and evolved further over the course of the centuries.

This is more than just the summation of two different forms of therapy. What makes laser acupuncture so interesting is that this combination improves and exponentially increases the effects of both acupuncture and phototherapy.

The invention of the laser was the actual milestone for phototherapy that made possible low-level laser therapy (LLLT) - the therapy with coherent light of low energy - a very sophisticated form of light therapy.

Laser acupuncture is not a further development of the therapeutic concepts of Acupuncture. These still apply as before. However, it constitutes an outstanding advance in acupuncture, as it exceeds the therapeutic successes of classic acupuncture with metal needles in many indications. Light needles (laser needles) are more than merely “friendly,” because they do not prick. In addition, they have photo-biological effects in the tissue which enhance the successful results of acupuncture and stabilize them. What is more, low-level lasers open up new therapeutic options for the user, regardless of the approaches of Acupuncture: they can also be used for photo-bio-stimulation in general (laser therapy) and as an information carrier for resonance effects (resonance therapy).

Photo-biological modulation is the primary effect of all three approaches.


Therapeutic light

Laser therapy is light therapy. Light is the part of electromagnetic radiation that is visible for human beings. This part of the electromagnetic spectrum ranges from blue-violet (with a wavelength of approximately 400 nm) to dark red (with a wavelength of approximately 700 nm). The limit of light perception depends on the sensitivity of the eye and can therefore not be determined precisely. The infrared and ultraviolet radiation border on the range of the visible light and are also often called light (UV light, infrared light).

However, it is not only our eyes that perceive light and decide about the colors of different wavelengths. Our entire body reacts to electromagnetic radiation. In photo medicine almost all parts of the light spectrum are used for therapeutic purposes. UV light, e. g., is used to treat neurodermatitis, and red light can help with middle ear inflammations, among other ailments.


Low-level laser light

Low-level laser therapy is the most subtle form of light therapy.

Laser is a form of “intensification of light": “LASER” is the acronym for Light Amplification by Stimulated Emission of Radiation.

Laser light is different than light from conventional light sources, such as a light bulb: it is monochrome (in other words, its spectrum of wavelengths is very narrow), the wavelengths oscillate in a phase (coherence) and the rays are parallel.

A laser unit is therefore a device which is able to generate parallel bundled and directed light of only one specific wavelength.

There are high power lasers enhance light energetically in order to destroy tissue with precision for surgical purposes, while there are low-level lasers use only a degree of energy intensification that is not dangerous for the body physiology. To make this important distinction, a low-level laser is often called healing laser, soft laser, bio-stimulation laser, therapy laser, or cold laser. . Low-level lasers can activate regenerative physiological processes in the entire body.

Universal applications

Low-level lasers can be applied universally: Today they have conquered nearly all special fields of medicine. This is unusual in medicine. What confuses patients most is that laser therapy is used like a panacea that can be encountered virtually anywhere. What is more: it is apparently also used in different ways - because everyone calls their method laser therapy:

A broad-area therapy laser: three methods

Laser therapy is the general term for various different methods. Depending on how the low-level laser is employed, the focus is more on other therapeutic. Photo-biological stimulation is the primary effect, which in laser acupuncture and resonance therapy is merely used for different purposes. Laser therapy encompasses three method:

  • Bio-stimulation
  • Laser Acupuncture
  • Resonance therapy

1. Bio-stimulation

The significance of light for physical and emotional health was well known in all cultures. The Rig Veda Samhita (about 1200 bc), describes the significance of light for everything that lives. The famous Greek physician Hippocrates (460-377 bc) used to treat skin and other diseases with sunlight.

Today low-level laser therapy is no doubt one of the gentlest of all light therapies. When applied correctly, the light energies that are employed are lower than those in all above-mentioned phototherapeutic methods.

A person who is sunbathing receives about 1000 joules per minute spread over his or her entire body. However, the precise Light energy of 3joules hitting the surface of the skin through infrared light, is sufficient to stimulate most acupuncture points. So, low-level laser therapy works with small light stimuli. The only reason they can have major therapeutic effects is that they trigger enhancement effects in the body and concentrate more light on, say, one acupuncture point compared to the surrounding area. In other words, the crucial impact factor in low-level laser therapy is not the radiation dose but the precisely directed communication with essential control centers for processes that take place within the body.

Today we know that the enhancement effects due to the absorption of laser light are achieved on the subcellular level. The primary mechanisms of low-level laser therapy are based on interactions between the photons and molecules in the intracellular space. Therapy lasers (when applied properly) transmit very low energy densities, which however are sufficient for this photo-bio-stimulation.

The secondary effects describe the biochemical changes of the metabolism and their manifestations at the tissue level which are induced by the primary mechanisms.

The secondary effects describe the biochemical changes of the metabolism and their manifestations at the tissue level which are induced by the primary mechanisms.

Primary stimulation effects

The primary effects of low-level laser therapy at the cellular level are attributed to the absorption of monochromatic near-infrared radiation by components of the respiratory chain. It causes an improvement of the electrochemical potential of protons, an increase in ATP, RNA and protein synthesis, and a boost in oxygen consumption, the membrane potential, and NADH synthesis.

Secondary stimulation effects

The activation of the cellular metabolism is the direct, primary, and decisive effect of photo-stimulation with a low-level laser. At the tissue level, this process translates into the effects which we associate with low-level laser therapy. It is these effects that made the technique famous. They are often summarized as the following five essential principles:

  • Anti-inflammatory effect
  • Analgesic effect
  • Regenerative effect
  • Circulation-improving effect
  • . Anti-edematous effect

Key parameters

The basic treatment parameters of low-level laser therapy are the radiation power, the power and energy density, and the wavelength.

The power (mW) of a laser is the rate at which energy is emitted. Its measurement unit is watt. Since the power output which is administered in low-level laser therapy is low, the unit is mW.

Power density = mW/cm2

The radiation energy which is applied in a treatment is calculated by way of the power (mW) and the treatment time. It is measured in joules (J), which is the dose unit.

Energy (joule) = Power (W) x Time (sec)

The treatment time can be calculated based on the laser power used.

The energy density (joule/cm2) is the radiation energy to which a selected tissue surface is exposed.

Energy density = Energy (joule)/cm2

The energy density is the treatment dose and constitutes the most important treatment parameter.

The wavelength of the laser beam is important with respects to ‘Penetration depth’. The greater the wavelength of a low-level laser (up to 1000 nm), the deeper it penetrates the tissue. Typically, red light with a wavelength below 700 nm and infrared light with a wavelength above 700 nm are used in low-level laser therapy, because they also penetrate deeper tissue layers.

2. Laser Acupuncture

Laser acupuncture is a synthesis of the rich experience of Traditional Chinese Medicine (TCM), which is thousands of year old, and modern science. In the past century, traditional Chinese acupuncture was picked up, advanced, and modified especially in the German- and French-, and later also the English-speaking countries. The most important further development, in addition to ear acupuncture, is no doubt laser acupuncture, i.e., the stimulation of the acupuncture points with low-level laser light.

Point stimulation with light

The mechanism by which light needles stimulate acupuncture points has two aspects:

1. Precision of the stimulus

The low-level laser can place a stimulus as precisely as a metal needle. It influences an acupuncture point via the same biophysical primary and secondary effects as in general bio-stimulation (discussed in Bio-stimulation above). One reason why this stimulus is exerted is that these effects are triggered precisely only in a narrowly defined tissue area, the acupuncture point. A stimulus is the result of pointed stimulation which stands out from the normal influences of the surrounding area.

2. Reflex bio-modulation

Contrary to a metal needle, however, the biophysical effect of the laser is not only that of providing a precise stimulus. It also initiates processes in the tissue which exceed this function. To put it differently: it impacts the acupuncture point beyond its significance as a stimulus agent.

If we assume that a therapeutically effective acupuncture point is “active” - i.e., painful, or otherwise “conspicuous” - then the tissue is in a physiological imbalance. The laser, however, can have a direct, positive impact on it. Since acupuncture is a form of reflex therapy, the harmonization of the reflexive expression of a disorder pattern has an additional positive impact.

Laser acupuncture offers advantages and benefits in addition to effects that are comparable with those of classic needle acupuncture.

Advantages of laser acupuncture over conventional metal needle acupuncture

  1. Short therapy duration (10-30 seconds/point).
  2. Points which are difficult or painful to treat with needles (mucous membranes, wounds, joints) can be included.
  3. Painless and non-invasive therapy (particularly suited for the treatment of sensitive patients, children etc.).
  4. Used in those cases for which classical acupuncture does not recommend the use of needles (asthenia).
  5. Aseptic, no risk of infections.
  6. Can be used to complement and extend the needle program, if additional points are required in order to optimize energy flow.
  7. Can be used to supply therapeutic and diagnostic information (Bio-frequencies), so called “Laser Resonance Therapy".
  8. Lasting stimulation with the Light-Needle. It seems to be even more effective than conventional needle acupuncture. Because once the fiber is placed no further manipulation is required.
  9. Side effects and complications, such as needle fainting or vasovagal syncope, occur considerably less often with laser acupuncture. Infections and hematomas cannot occur. Potentially dangerous acupuncture points may also be treated by beginners. Laser acupuncture is noninvasive and traumas to the skin are impossible.
  10. The ability of the acupuncture points to respond often decreases in elderly patients. Laser acupuncture has a positive impact on degenerative tissue processes at the neurovascular bundles of acupuncture points.

3. Resonance Therapy

The resonance therapy is based on the assumption that resonance phenomena increase the absorption of photons and may further enhance the photo-bio-stimulatory effects of low-level laser therapy.

Resonance therapy is based on the finding that resonance-modulated laser beams can interact with specific organs, tissue types, and regulation levels of the organism.

Life on Earth is the result of the interplay of diverse fields and vibrations. Natural background radiation, such as the earth’s magnetic field, electromagnetic fields, and cosmic radiation have made the development of life possible to begin with and have had a lasting impact on it. These influences still exist to this day and advance evolution. For this reason all life on Earth is adapted to these fields, using them in various ways to synchronize life processes.

Each individual organism also represents a self-regulating, vibrating system. All metabolism processes that take place in the body contribute toward it. The number of chemical reactions in one cell is estimated to be between 30,000 and 100,000 per second. Extrapolated to the total human organism, this translates into about 1018 reactions per second. Each of these biochemical reactions involves the binding or separation of molecules. Ultimately the atoms that are involved exchange electrons among one another, oscillating back and forth between low-energy and high-energy states.

Yet, the organism is not a self-contained system. Rather, it interacts with its environment and reacts to external stimuli (vibrations). And so there are countless interferences between the natural frequency of the organism and the fields surrounding it. These interactions have a direct impact on the organism and its metabolism processes.

If an external stimulus matches the natural frequency of the organism, it can amplify it and trigger specific reactions. Laser therapy with resonance frequencies is based on this insight.

However, every organism has not only one but a whole range of different natural frequencies. Electromagnetic waves, such as laser light, can specifically resonate with one of these natural frequencies, thus initiating or supporting healing processes.

Primary resonance phenomenon: wavelength

The primary stimulation effects of low-level laser therapy are resonance reactions to light wavelengths. Basic research has revealed that the mitochondrial wall contains photo acceptor molecules which, can be stimulated by specific light wavelengths. The stimulation of these photo acceptor molecules triggers the biochemical reactions of the respiratory chain and boosts ATP production. The different photo acceptor molecules absorb light of different wavelengths from the ultraviolet and blue range all the way to the red and infrared band.

Superimposed resonance phenomenon: resonance modulation

In addition to the primary stimulation effects which low-level laser therapy triggers in the mitochondrial membrane, the pulsing of the radiation density may also trigger an amplification mechanism. After all, the photo acceptor molecules undergo stimulation and refractory phases that are similar to those of the membrane potential of the cell. Synchronizing these phases through pulse stimuli intensifies the effect exponentially.

Laser frequencies and those who discovered them

Resonance-modulated laser therapy was developed in the 1970s by the French physician Dr. Paul Nogier. He is also regarded as the one who discovered the ear somatotope and the founder of auricular medicine.

NOGIER frequencies

Dr. Paul Nogier (1908-1996) is considered the father of modern ear acupuncture (auricular therapy) and frequency therapy. He studied medicine in Lyon, including homeopathy, acupuncture and brain stimulation.

Nogier discovered auricular therapy in 1951 and first published his findings in 1956. In 1966 he discovered the RAC (VAS).

The NOGIER frequencies are pre-programmed in the Lasers devices and have been used for more than 30 years. There is a low and high potency. Both ranges are used for the same indications. Below is a brief summary of the NOGIER frequencies, which are known as “A, B, C, D, E, F, and G”.

BAHR frequencies

The German physician Dr. Frank Bahr discovered a large range of frequencies which have been in use for many years.

BAHR 1, BAHR Special, teeth, skeletal system and chakras are among the most important. All frequencies are pre-programmed in the Laser devices and can be controlled by the RAC. The BAHR 1 frequencies are known as “1, 2, 3, 4, 5, 6, and 7”.

REININGER frequencies

Dr. Manfred Reininger, Austria, was the first who published frequencies of the meridians. In the previous years he found a large number of different frequencies related to the human body, diseases and the environment.

Reininger RI, RII, RIII, each with 7 frequencies, and Level frequencies with 17 frequencies used by advanced practitioner.

Frequency modulation / application

Laser devices offer a large range of comprehensive medical proven Bio-frequencies to transfer healing information and generate resonance in the body. To achieve this, the signals need high coherence and must be clear/clean (monochromatic).

Coherent and monochromatic signal

The signal (information, correct and exact bio frequency) must correspond to the receiver (cell/nerve system) like a key to a lock.

The laser beam as carrier of information

By using certain frequencies, the therapist will send specific therapeutic information to the patient to bring the cells and the nerve system into resonance (so called Laser Resonance Therapy).

Example: Only the correct frequency will create resonance.

The laser beam is used as the carrier of the information. If a perfect resonance is reached, there will be a high therapeutic effect with minimum energy requirement.

The frequencies are applied for:

  1. Diagnosis
  2. Therapy

Frequencies are applied to relevant parts of the body (information therapy, Laser Resonance Therapy). To improve the therapeutic effect the combination of various frequencies is beneficial. Some sophisticated Laser devices offer customized therapy programs.
