Laser Therapy

If you are not familiar with laser therapy, here is a short introduction to the technology and the treatment, as well as the benefits of using laser therapy.


How does laser therapy work?

Laser therapy is based on the following principle from the world of physics: Energy cannot be created or destroyed. Instead, energy can transform and can be transferred from one object to another.

With laser treatment, the energy from the laser light is transferred to the cells in the body where it can be used as fuel. With its unique characteristics and energy, the laser light penetrates deep into the tissue, into each individual cell and every little mitochondrion, where the energy is absorbed and thereby transferred.


This way, the cell gets the energy to perform the tasks that it is already programmed to do, including the body’s natural healing process.


If, for instance, you apply laser energy following an injury, the result is an acceleration of the body’s natural healing process. An example of this, a sprain, is illustrated in the diagram “Accelerated Natural Healing”.


The mitochondrion’s function

Most of the cells in our body contain one or more small units called the mitochondria. The mitochondria’s function is to produce fuel for the cell, ATP, with the help of the glucose in our bloodstream. ATP stands for Adenosine Triphosphate that the cell uses when it performs its tasks.

Every injury to the body, acute or chronic, leads to an energy deficit, which is characterized by a reduced production of ATP.

This situation has been re-created in the lab where living cells were put under “nutritional stress”, i.e. they did not receive nutrition during a certain period of time.

This leads to an imbalance in the Na+/K+ (Sodium/Potassium) pump and the electric membrane potential, as well as a reduction in the mitochondrial production of ATP.

By adding laser light – and nothing else – it has been demonstrated that all parameters have normalized, including an increase in the production of ATP to 100%.


The principle of Accelerated Natural Healing

Laser therapy is based on the principle of Accelerated Natural Healing, which is reflected in the following features and benefits:


  • Biostimulating laser therapy accelerates all phases of the body’s natural healing process.
  • Laser therapy provides energy to the cells by increasing the production of ATP, which leads to a significant increase in cell activity.
  • This leads to, among other things, a quicker coagulation after acute injuries, which reduces edema.
  • Laser therapy has a strong diminishing effect on inflammation, both in chronic and acute instances.
  • Laser therapy increases the production of collagen tissue and thereby contributes to quicker wound healing.
  • Laser therapy mobilizes the body’s natural immune system and increases its ability to fight bacteria, viruses and fungus.
  • The blood flow is increased, even in areas with reduced circulation and/or chronic muscle tensions.
  • Laser therapy has a pain relieving effect, partly by reducing the problem that caused the pain in the first place, and partly by stimulating the body’s production of endorphins and encephalin.
  • Biostimulating laser therapy has no known side effects. It simply helps the body do what it is already programmed to do – only much faster.


All these factors, which have been documented in thousands of scientific studies over the past 35 years, lead to what we call:

*) When talking about biostimulating laser therapy, several words describe the same thing: soft laser, cold laser, low intensity laser. The internationally recognized name for it is Low Level Laser Therapy, LLLT.


What is laser?

The word “LASER” is short for Light Amplification by Stimulated Emission of Radiation. In their book “The New Laser Therapy Handbook”, Tuner and Hode mention the interesting fact that the original thought was to use the word “Oscillation” instead of “Amplification”. However, this, unfortunately, would have resulted in the word “LOSER”.


monochromatic light 300Laser is, then, amplified light. The laser beam can be within or just outside the spectrum visible to the human eye, but only at one wavelength at a time. The European standard IEC 601 describes laser this way: “Any device which can be made to produce electromagnetic radiation in the wavelength range from 180 nm to 1 mm primarily by the process of controlled stimulated emission".


Laser light is monochromatic, which means that it is emitted at only one wavelength, as opposed to sun light, for instance, that spans several wavelengths/colors – this is easily seen when a rainbow appears while rain and sunshine are present at the same time


Laser is also coherent, which means that the wavelengths are emitted in phase, in other words, they occur at the same time and put out more power.


kohaerens 300A way to illustrate this is by looking at the difference between the power of ripples in water and the power of large, synchronized waves.

This makes them suitable for penetrating underlying tissue with a greater effect than sunlight or the light from a flashlight, which are non-coherent light sources.

The following chart illustrates the difference between coherent and non-coherent light combined with the output power, i.e. the size of the laser, by comparing one of our PowerLasers for therapeutic use to an industrial laser and other light sources:


Output   power Non-coherent Coherent
500mW Flashlight PowerLaser
100 W Light bulb Industrial laser
