For centuries, light has been used to heal. Ancient Egyptians constructed solariums to treat various conditions. Light has powerful medical benefits, and with recent technologies evolving rapidly, we are capable of using light to target specific light-absorbing molecules to treat select tissues.
Low Level Laser Therapy administers an exact wavelength, or color of light, in a coherent manner. Coherence is an important characteristic for maximizing the depth of light penetration. This is key, as a specific dose (or energy) of light is required to trigger a biological response.
Although the exact mechanism remains elusive, studies have made tremendous progress to understand how LLLT alters cell function and, in turn, treats certain medical conditions. In order for laser therapy to modulate cellular behavior, light energy must first be absorbed.
Concurrently, the red wavelength (635 nm) is used to activate immune cells and increase circulation, steps that reinforce the body’s natural defense against foreign pathogens.
Since 1966, lasers have been used in non-surgical applications, including for experimental wound healing, pain reduction, and acute inflammation of different tissues. Today, evidence based medicine provides the necessary support for effective treatment of injuries and diseases that have no current treatment such as spinal cord and brain injuries, acute inflammation, soft and hard tissues, and metabolic diseases.
LLLT remains a controversial treatment, but with important objective studies being conducted to evaluate the technology, this subtle, noninvasive treatment is becoming an appealing therapeutic option.
