The history of cold laser therapy dates back to the 1960s, with early research exploring its potential in wound healing and pain management. Since then, advancements in technology have led to the development of sophisticated devices capable of delivering targeted laser energy with greater precision and efficacy.

Cold laser therapy devices operate based on the principle of photobiomodulation, where light energy interacts with cellular components, triggering a cascade of biochemical reactions that promote healing and reduce inflammation.

Introduction to Cold Laser Therapy Devices

Cold laser therapy devices, also known as low-level laser therapy (LLLT) devices, are medical devices that use specific wavelengths of light to stimulate cellular processes and promote healing. These devices emit a beam of low-intensity, non-thermal light, often in the red or near-infrared spectrum.

The basic principle behind cold laser therapy is the interaction of light with biological tissues. When light photons from the laser interact with cells, they are absorbed by specific molecules, primarily cytochrome c oxidase, a key enzyme in the electron transport chain responsible for cellular energy production.

This absorption of light energy triggers a cascade of biochemical reactions, leading to various therapeutic effects.

History of Cold Laser Therapy
