IR Therapy


unlight absorbed by chloroplasts in plant cells permits formation of starch. Sunlight absorbed by human skin generates vitamin D. Some wavelengths of light, including near infrared and ultraviolet (UV) light cannot be seen with the human eye, and yet cause biologic effects.

A light emitting diode (LED) is a semi-conductor device that emits incoherent narrow-spectrum light. Some LED devices are also monochromatic, such as Anodyne® Therapy Systems.

  • Infrared Light from both lasers and LEDs disperse once the light contacts body tissue. The depth to which they penetrate has nothing to do with whether the light is lased, but rather has to do with the wavelength and energy density.

    Infrared Light output from LEDs possess all the attributes of laser radiation except coherence. Findings at the cellular level would imply that the property of coherence is largely unnecessary for the clinical effects of these devices.

    At a particular wavelength, light that is emitted out of a LED or a Laser will have similar clinical effects on body tissue. Effects can be further enhanced by increasing the surface area of treatment device, and by increasing the energy density.

    Lasers are usually enclosed behind glass and recessed a few centimeters; where as the LEDs of Anodyne® Therapy Systems are in direct skin contact.

    Direct contact minimizes the amount of light refracting off of the skin, thus increasing the amount of light absorbed by the blood vessels.
