What is Class IV Laser Therapy?
K-LASER Dynamic therapy uses several pulse frequencies to produce a combination of analgesia, inflammation reduction, bio stimulation and antimicrobial effects, thus accelerating the regeneration of tissues and increasing cellular energy. Cells are then able to thus absorb nutrients more quickly and eliminate waste substances. As a result of the exposition to laser light, the cells that constitute tendons, ligaments and muscles are repaired more quickly.
K-LASER Dynamic Therapy has anti-oedemic effects since it produces vasodilation while activating the lymphatic drainage system, which results in swelling reduction.
The Importance of Wavelength
The wavelength of light not only determines colour in the visible spectrum, but also it's depth of penetration into the body system. In general, longer wavelengths allow energy to penetrate more deeply into the body than shorter wavelengths. Wavelengths also have different absorption efficiencies for particular body structures.
< 445 nm - The wavelength that best interacts with molecules at the systemic level, absorbed by both melanin and hemoglobin more effectively than infrared wavelengths do. This wavelength is also particularly effective on numerous bacterial strains (Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Phrphyromonas gingivalis, Helicobacter pylori), exercising its antiseptic and bactericidal action, excellent results in tissue incisions, both for surgical and vascular purposes. Acts by stimulating the immune system activation.
< 660nm - This wavelength is well absorbed by the melanin contained within skin ensuring a high energy concentration within the superficial tissue layers. Laser therapy provides excellent results in wounds healing and scar tissue regulation as the light both inhibits bacterial proliferation and increases cellular growth.
< 800 nm - K-LASER research determined that Cytochrome C enzymes absorbed best at 800nm. Cytochrome C oxidase is the terminal enzyme of the respiratory chain and determines how efficiently cells convert molecular oxygen into ATP. An ATP molecule is generated for each oxygen-reduction cycle accomplished. Photon absorption from laser therapy accelerates this cycle and so increases cellular ATP production, resulting in faster healing and cell division.
< 905 nm - Oxygen is released in variable percentages in the blood: the faster it is released, the more oxygen needs to be transported to the cell in order for the natural healing processes to take place. This wavelength is absorbed by haemoglobin, water, melanin and Cytochrome C oxidase. When it is absorbed, more oxygen is available to the cells
< 970 nm - Blood, the main transport system, provides the cells with all the elements which are necessary to their metabolism, such as oxygen and nutritional substances, thus removing catabolic products. This wavelength is able to absorb most of the water contained in our body and a large part of the energy delivered by the therapy is transformed into heat. The deep tissue layers are thus transformed into localised heat points that create temperature gradients at cellular level. They also boost local microcirculation thanks to the increase.
< 1064 nm - This wavelength generates a double effect, since at the same time it is absorbed by two primary chromophores: Melanin and Water. The combination of the two activation peaks enhances the advantage of using this wavelength. Being more penetrating than Melanin, 1064nm wavelength is optimal when we need to treat dark phototypes, in which the short wavelengths would not be sufficiently penetrating because absorbed too early by the skin.
The Frequency of Laser Light
Lasers can deliver their light energy either as a Continuous Wave (always on) or pulsed.
The number of times the light is switched on or off each second is called the Frequency.
Different pulse frequencies elicit different physiological responses depending upon the anatomical part being treated (i.e. bone, soft tissue, and fat).
K-LASER lasers also provide an Intense Super Pulse (ISP) mode that deliver bursts of high peak power for a short period of time.
Laser Power
The greater the depth of the cells you are treating the more energy is needed to produce a therapeutic effect. By starting out with more energy at the skin surface treatment times are dramatically reduced compared with less powerful lasers.

Why Ease-of-Use is important
Knowing which combination of Wavelength, Power and Frequency is most appropriate for each condition is the result of decades of
on-going research. In addition, to achieve to best therapeutic effect K-LASER protocols can also have up at 12 different phases of treatment each with their own Wavelength, Power and Frequency settings.
To be a practicable modality in practice Laser Therapy must be simple and quick to perform. K-LASER has the most intuitive easy to use touch-screen software available. Simply select the species, condition, coat colour and any additional parameters like ‘Weight’, or ‘Wound Size’. K-LASER is then automatically calibrated to deliver the optimal treatment protocol. K-LASER has done everything possible to make laser therapy as simple as possible.
