K- Laser Therapy

What is Laser Therapy?

Laser Therapy is the use of specific wavelengths of light (red and near-infrared) to stimulate the body’s natural ability to heal.  The effects of laser energy include improved healing time, pain reduction, increased circulation and decreased swelling.


Laser Therapeutic Effects

During each painless treatment, laser energy increases circulation, drawing water, oxygen, and nutrients to the damaged area. This creates an optimal healing environment that reduces inflammation, swelling, muscle spasms, stiffness, and pain. As the injured area returns to normal, the function is restored and pain is relieved.


Cellular Effects

During K-Laser USA Therapy, infrared laser light interacts with tissues at the cellular level increasing metabolic activity within the cell. By improving the transport of nutrients across the cell membrane, the increased production of cellular energy (ATP) is stimulated. The cascade of beneficial effects that follows includes increasing cellular function and tissue repair.


What You Need to Know About Lasers

Lasers are classified according to their power output:

  • Class 3a—maximum of 5 milliwatts of power (standard laser pointer)
  • Class 3b—maximum of 500 milliwatts/0.5 watts
  • Class 4—anything over 500 milliwatts/0.5 watts

The most significant issue with the clinical use of lasers is the depth of penetration.

Most class 3a lasers only use a red wavelength – 635 nanometers in the visible red. When you look at the depth of penetration with a laser, red laser light only penetrates about one to two millimetres (far less than 1/8 inch) into the human body.

However, infrared lasers (around 800 nanometers) penetrate far deeper and able to go several centimetres, into your body which will reach most tissue injuries.

Power is also another crucial factor when it comes to laser therapy. Power is measured in watts, and you can think of it as the brightness of the light. A higher-powered laser is a brighter light, and it can produce more energy per unit of time. When it comes to doing laser therapy treatment, a higher-powered laser (Class 4) provides two benefits:

  • A therapeutic dose of laser light can be applied to a much larger volume of tissue
  • By shining that brighter light at the surface, photons of light are able to penetrate deeper into the tissues, which allows you to treat deep-seated pain conditions

Health Benefits of K-Laser Class 4 Laser Therapy

Basically, three things happen during K-Laser treatment. First, infrared laser therapy treatment helps reduce pain, reduce inflammation, and enhance tissue healing—both in hard and soft tissues, including muscles, ligaments, or even bones.

The basic mechanism of how it works, we are enhancing the microcirculation. We are getting more red blood cells flowing to the area. enhancing the venous and the lymphatic return from the area. We’re also increasing oxygenation of those tissues. We are stimulating the haemoglobin molecule to dump off oxygen at the treatment site, so we are increasing the oxygenation of those tissues.

The treatment stimulates the cytochrome oxidase enzyme in the cells’ mitochondria.  Specifically, injured cells are targeted because damaged cells are more readily accepting of photons of light, whereas healthy cells don’t need this extra energy.

Now, lasers are also used in other areas of medicine, specifically in surgical interventions where they’re used for cutting, removing tattoos, and a lot of other dermatological applications. But class 4 K-Laser does not do that. The K-Laser can produce up to 15 watts, and the laser light is allowed to diffuse to a spot size about that of a quarter, whereas ablative lasers, the ones used for surgical cutting, are closer to 100 watts, and the laser light is focused to the tiny spot size.

By shining that light on a tissue, we are getting that ATP energy produced, whereas your surgical lasers, hair removal lasers, or tattoo removal lasers, are designed to cut or ablate the tissues. They have a very, very high-powered density, a very high concentration on that laser.”


The infrared wavelengths used in the K-Laser allow for targeting specific areas of the body. The K-Laser is unique in that it is the only Class 4 therapy laser that utilizes these three infrared wavelengths, allowing for deep penetration into the body to reach areas such as your spine and hip (the K-Laser also has a 100-milliwatt, 660-nanometer visible red which, again, is excellent for superficial wounds):

  • 650 nanometres inhibit bacteria and promote cell growth, and has incredible results in wound healing and scar tissue regulation.
  • 810 nanometres penetrates the deepest and is at a peak of absorption for the cytochrome oxidase enzyme
  • 915 nanometres most efficiently targets the haemoglobin molecule
  • 980 nanometres most efficiently stimulate microcirculation in the tissues


Class 4 laser therapy can be effectively combined with a number of other treatment modalities, including various soft tissue mobilization techniques



·         How often should a patient be treated?

Acute conditions may be treated daily, particularly if they are accompanied by significant pain. More chronic problems respond better when treatments are received 2 to 3 times a week, tapering to once a week or once every other week, with improvement.

·         How many treatments does it take?

This depends on the nature of the condition being treated. For some acute conditions, 4 to 6 treatments may be sufficient. Those of a more chronic nature may require 6 to 12 (or more) treatments. Conditions such as severe arthritis may require ongoing periodic care to control pain.

·         How long before the results are felt?

You may feel an improvement in your condition (usually pain reduction) after the very first treatment. Sometimes you will not feel improvement for a number of treatments. This does not mean that the condition is not improving. Each treatment is cumulative and results are often felt after 3 or 4 sessions.

·         Can laser therapy be used in conjunction with other forms of treatment?

Yes. Laser therapy is often used with other forms of treatment, including physical therapy, chiropractic, massage, soft tissue mobilization, electrotherapy and even following the surgery. Other healing modalities are complementary and can be used with laser to increase the effectiveness of the treatment.

·         Does laser therapy hurt? What does treatment feel like?

There is little or no sensation during treatment. Occasionally one feels a mild, soothing warmth or tingling. Areas of pain or inflammation may be sensitive briefly before pain reduction.

·         Are there any side effects or associated risks?

During more than twenty years of use by healthcare providers all over the world, very few side effects have ever been reported. Occasionally some old injuries or pain syndromes may feel aggravated for a few days, as the healing response is more active after treatment.

·         How long does each treatment take?

The typical treatment is 4 to 8 minutes, depending on the size of the area being treated
