Laser therapy acts under several aliases depending on the medical context or the specific feature being highlighted. The most common alternative names you will encounter are cold laser therapy and low-level laser therapy.
Regardless of which term is used, these names refer to the same therapeutic approach: a non-invasive treatment that uses light to interact with tissue without generating heat.
Decoding the Terminology
Understanding why these specific names are used helps clarify the nature of the treatment.
Why It Is Called "Cold Laser"
The term cold laser therapy is used to distinguish this treatment from surgical lasers.
Surgical lasers are designed to cut, cauterize, or destroy tissue by generating intense heat.
In contrast, "cold" lasers operate at a frequency that does not raise the temperature of the body tissue, making them safe for non-destructive therapy.
Understanding "Low-Level Laser"
The name low-level laser therapy describes the power output of the device rather than the temperature.
It indicates that the energy levels utilized are strictly regulated to be low enough to stimulate cellular function without causing thermal damage.
This technical descriptor is often used to differentiate the device from high-power, industrial, or surgical class lasers.
Common Pitfalls to Avoid
Confusing Marketing with Methodology
Different clinics or manufacturers may favor one term over the other for branding purposes, often making them sound like distinct procedures.
You might see a chiropractor advertise "cold laser" while a physical therapist offers "low-level laser."
Do not be misled into paying for two "different" treatments; recognize that the underlying mechanism is identical.
Making the Right Choice for Your Goal
When researching or discussing this therapy with a provider, use the terminology that best fits your context.
- If your primary focus is academic research: Search for Low-Level Laser Therapy, as this technical term is frequently used in clinical studies and medical literature.
- If your primary focus is finding a local provider: Look for Cold Laser Therapy, as this is the colloquial term most often used in patient-facing marketing to emphasize safety and comfort.
Recognizing these terms as synonyms ensures you can compare treatments accurately and avoid unnecessary confusion.
Summary Table:
| Term | Primary Context | Key Characteristic |
|---|---|---|
| Cold Laser Therapy | Patient-facing & Clinics | Emphasizes non-thermal, safe treatment without heat. |
| Low-Level Laser Therapy (LLLT) | Clinical & Academic Research | Highlights the regulated low-power output for cellular stimulation. |
| Photobiomodulation (PBM) | Scientific Literature | Describes the biological process of light interacting with cells. |
| Soft Laser | General/European Markets | Focuses on the gentle, non-surgical nature of the device. |
