Although they don't make a big deal about it, our research indicates that Multiradiance is the largest therapy laser company in the world. After selling over half million systems, they have established themselves and their products as the most popular options in the cold laser market. In addition to the products we sell, they offer several other systems with similar specs that are branded for different markets. All these systems revolve around a "super-pulsing" laser at 905nm. This is where all the "heavy lifting" is done with Multiradiance products but they have many other features that help optimize this core technology to make their system more flexible.

Originally, their main products were TerraQuant systems but the TerraQuant desktops have been phased out and replaced with the MR4 series. Each generation of Multiradiance's new product is accompanied by more features. Here are the current options that we sell. The TerraQuant TQ Solo is the only TerraQuant system still in production. All the other products are MR4 systems.

Throughout the world, cold laser therapy is used to treat acute/chronic pain, back pain, carpal tunnel, arthritis pain, fibromyalgia, tennis elbow, muscle strain, bursitis, tendonitis, and many other injuries. The MR4 and TerraQuant® laser therapy system is unlike any other cold laser on the market. The TerraQuant/MR4® laser therapy system provides pain relief and healing through an FDA cleared modality using patented multiple therapeutic radiances. The different radiance work synergistically to accelerate treatments and reduce recovery times. The MR4 Family of Lasers use a combination of:

  • Super pulsed laser
  • Pulsed broadband infrared SLDs
  • Pulsed red light
  • Static magnetic field

Successful double blind clinical trials prove it.

Numerous randomized double blind clinical trials have showed efficacy of the TerraQuant and MR4® systems on various health conditions. An 88% positive effect was demonstrated in studies done on the efficacy of the TerraQuant® in relieving pain caused by arthritis of small and medium joints. Click here to see the study. There are dozens of additional clinical studies and papers available for your review on this site. In addition to specific studies on the TerraQuant®, over 4,000 studies have been conducted worldwide to validate the effectiveness of laser therapy.

Healing with light at the cellular level

The goal of cold laser therapy is to deliver light energy units (in photons) to damaged cells. Photons are absorbed by the cells and stimulate the mitochondria to accelerate production of ATP. The biochemical increase in cell energy helps accelerate the bodies healing process by transforming cells from a state of damage to a stable, healthy state.

MR4® Lasers excels where most laser devices fall short

  • TerraQuant/MR4® Super Pulsed Lasers deliver higher peak power while maintaining the highest degree of safety of any therapeutic laser (Up to 50 watts)
  • Multiradiance claims that TerraQuant/MR4® devices are more effective in delivering photons to deep tissues compared to Class I-III continuous and modulated lasers
  • Unlike Class IV continuous lasers, The pulsing technology of the TerraQuant/MR4® laser eliminates the risk of thermal damage to a tissue
  • More power than most class IV lasers (25,000-50,000mW super pulsed laser power)

All the TerraQuant and MR4® systems are turnkey systems, meaning they are easy to set up and use. The TerraQuant console has two ports that allow for simultaneous use of 2 emitters. The MR4® family of products include emitters for various applications from pinpoint probes to large treatment emitters.

Why TerraQuant/MR4 Laser Therapy?

Treatments are painless, drug-free, and non-invasive. Most importantly, they are effective.

TerraQuant laser therapy products are offered at a lower price than other competitor's products due to the volume manufactured. Efficacy, ease-of-use and profitability have been realized in practices coast-to-coast and in over 30 countries.

The TerraQuant® is unique because it uses 3 different techonologies to acheive maximum healing:

  • 1. Super Pulsed Laser (905nm) produces a high power level of impulse light at a billionth of a second. It is the high power during each pulse that drives the photons, or light energy, to the target tissue, up to 10-13cm (4-5 inches) deep. The TerraQuant's high peak power of up to 50,000mW creates a higher photon density, delivering the highest concentration of photons for healing and providing the deepest tissue penetration. Super pulsed laser strongly influences pain reduction, the improvement of microcirculation and increases cell metabolism in the form of ATP production.
  • 2. Pulsed Broad Band Infrared Emitting Diodes (875nm) penetrate shallower tissue depths than the laser but provide an overall broader spectrum, when compared to laser radiation, by gently heating the surface tissue layer.
  • 3. Pulsed Red Light (660nm) penetrates shallower tissue depth and has beneficial anti-inflammatory effects.

Working synergistically, the multiple radiances of the TerraQuant® Laser Systems create the optimal biological environment for accelerated healing and pain relief. The use of the preset frequencies, allow clinicians and home users to control the depth of the therapeutic energy from the surface up to 13 cm (5 inches) deep.

TerraQuant and MR4® are one of the main laser therapy standards worldwide.
