Real Science. Real Results.
The use of laser is a high tech, non-invasive approach to therapy and healing that is reshaping medicine and the way that patients are being treated while improving human health through photomedicine solutions. Research is quickly progressing in identifying conditions that can be treated effectively and in facilitating new development in therapy laser technology.
All light is composed of photons. Photons are small packets of light energy in the form of waves with a defined wavelength and frequency. Photon energy is able to more effectively penetrate the skin and underlying structures, therefore accelerating the healing process.
LASER: Visible and Near Infrared (NI) Light
All light is not the same. It is measured in wavelengths, with each wavelength of light representing a different color of the spectrum. LASER (Light Amplification by Stimulated Emission of Radiation) can be used as a therapeutic device which produces monochromatic (one specific wavelength), coherent (constant phase) and polarized (directional) light. Near infrared (NI) light uses invisible, near infrared wavelengths between 700 and 1200 nm. Many published studies refer to the use of laser as Low-Level Laser Therapy (LLLT) or High-Intensity Laser Therapy (HILT). Laser studies have been performed with isolated live tissue samples, animals, and human subjects.
MECHANISM OF ACTION: Photochemical
When applied to an organism, Laser light, tuned to specific wavelengths and frequencies, stimulates metabolic processes at the cellular level and acts by inducing a photochemical reaction in the cell, as biostimulation or photobiomodulation. Studies have shown that when tissue cultures are irradiated by Lasers, enzymes within cells absorb energy from laser light. Chromophores are components of various cells and sub-cellular organelles which absorb light. The stimulation of Chromophores on mitochondrial membranes incites the production of ATP. Visible (red) light and Near Infrared (NIR) are absorbed within the mitochondria and the cell membrane. This produces higher ATP levels and boosts DNA production, leading to an increase in cellular health and energy.
Photobiomodulation Therapy (PBMT) has been officially defined as a form of light therapy that utilizes non-ionizing forms of light sources, including lasers, LEDs, and broadband light, in the visible and infrared spectrum. It is a NONTHERMAL PROCESS involving endogenous chromophores eliciting photophysical (i.e., linear and nonlinear) and photochemical events at various biological scales. This process results in beneficial therapeutic outcomes including but not limited to the alleviation of pain or inflammation, immunomodulation, and promotion of wound healing and tissue regeneration.
