The world of laser therapy can be a confusing place. Terms like class IV, cold laser therapy (CLT), low-level laser therapy (LLLT), and even photobiomodulation (PBM) are all over the internet and can make digesting information about therapeutic laser treatment hard. In this blog post we’ll be attempting to answer some common questions, point out important information to look for, and hopefully provide you with enough basic laser knowledge to ensure you get the most out of your laser therapy experience.

We’re often asked what Class IV, CLT, LLLT, and PBM mean, so we’ll begin with defining those terms. Class IV describes the types of lasers that are used in laser therapy. These lasers are typically higher powered and allow for better tissue penetration than class I-III lasers, which are found in your home, office, or manufacturing.

When laser therapy first became available for human use many terms were coined to describe the therapy process. These terms included cold laser therapy (CLT) and low-level laser therapy (LLLT). As with most therapy devices once laser therapy became available to the public there was a rash of late-night devices that hit infomercials everywhere claiming to fall under these categories. This influx of inferior machines spurred the need in the laser world for clear barriers in what laser therapy is and can do. Today, Photobiomodulation (PBM) is considered the appropriate term for the use of laser therapy on tissue.

What is Laser Therapy and what does it do?

 Laser therapy is the non-invasive, non-thermal application of light energy to stimulate cells. Once stimulated by the near-infrared light, cells in the affected area generate more energy and undergo self-repair. There are no known negative side effects from the use of PBM on cells.

When looking into laser therapy remember that not all laser devices are created equal. It’s important to use a PBM provider that utilizes a class IV laser that works somewhere between 808-908nm wavelengths. These ranges are great for not only tissue regeneration, but also in managing inflammation, and pain relief.

Can I be treated if I don’t have a diagnosis?

Laser therapy should always be performed by knowledgeable staff and under the direct supervision of a physician. Currently, some establishments do not require a diagnosis before treatment begins. Doing so is a bit like shooting at a target blindfolded. Treatment protocols for conditions vary widely in time, intensity, and technique. Having a diagnosis before treatment is essential in evaluating the efficacy of a treatment protocol for the patient, and in understanding how to manage treatment for the best possible results.
