How Veterinary Laser Therapy Works: MR4 ACTIVet PRO vs. High Powered Class IV Lasers

Multi Radiance Medical,

the global leader in the development

and manufacturing of super pulsed lasers,

is setting the new standard for veterinary laser therapy

with the ACTIVet PRO,

a cordless, ultra-portable laser therapy system

that combines high-power super pulsed lasers

with infrared, red and blue LEDs.

The synergistic optimization activates the entire phototherapeutic window,

significantly reducing treatment times

and delivering consistent, reproducible outcomes.

The MR4 ACTIVet PRO's super pulsed laser

produces a burst of highly focused peak power light

at a billionth of a second.

It's so fast with each burst

that it eliminates overheating of the skin.

The result is a low thermal influence on the skin

from maximizing the dose to the target

and the beneficial phototherapeutic effect.

Super pulsed laser therapy is the most effective method

to promote natural healing on both companion and equine animals.

Clinically, it improves bone and soft tissue health,

as well as reduces pain,

while managing inflammation from injuries or illness.

High-powered and high-intensity continuous wave lasers

often penetrate poorly through the skin.

This inefficiency overheats the superficial structures

and negatively affects healing or worse.

Cellular death, or apoptosis,

can be triggered by this excessive heat

that is not always detectable during application.

The resulting effect on the tissue

is no longer seen as beneficial,

but as a negative photothermal reaction of the Class IV lasers.

Exposing injured cells to low levels of red and near-infrared light

activates many beneficial biological pathways,

including cellular respiration.

When absorbed by the mitochondria,

the light energy helps oxygen displace nitric oxide (NO),

an important vasodilator,

to normalize the production of adenosine triphosphate (ATP)

that was reduced following the injury.

This process results in a small amount

of reactive oxygen species (ROS)

that activates beneficial transcription factors,

and the cell is now able to restore normal function or initiate repair.

Injured cells exposed to high-intensity lasers

experience a rapid temperature increase.

In response, heat shock proteins (HSP) begin to appear,

and the mitochondria begin to overproduce reactive oxygen species.

The increased oxidative stress from the combination of ROS and HSP

results in inflammation and eventually apoptosis.

This is not phototherapeutic, it's photothermal.

Before any positive effect can occur,

the light must be absorbed by the targeted tissue.

That means the light must pass through the skin.

The ACTIVet PRO uses multiple wavelengths that work synergistically

to increase the overall delivery of light into the tissue.

This not only prevents tissue overheating,

but allows for a much lower dose.

Higher-powered lasers such as the Class IV

use technology that is commonly overpowered to reach the target,

which is minimal at best,

and also negatively generates excess heat on the skin.

Class IV lasers often utilize a single, overpowered wavelength

that penetrates too poorly through the skin

to deliver an adequate amount of light at the target.

This produces so much excessive heat

that any beneficial effect is lost due to tissue heating.

The Depth of Penetration Time Profile

is the penetration of light through the tissue over time.

Super pulsed lasers penetrate deeper

using less energy in comparison to continuous wave,

high-powered lasers.

Studies show that a Class IV laser can

only get the same result of the ACTIVet PRO

by increasing the power over 1,600%.

When a favorable depth of penetration time profile exists,

less is more.

Less energy provides more light

and favorable depth of penetration to the target.

Today Multi Radiance's safe, powerful, super pulsed lasers

are the number one choice of veterinary professionals worldwide,

more than 90 college and professional sports teams in the US and Canada,

active and retired military healthcare facilities,

plus tens of thousands of private practices in over 30 countries worldwide.
