| THREE MAIN WAYS: LOW LEVEL LIGHT THERAPY WORKS WITH THE BODY
UNDERSTANDING WAVELENGTH AND PULSATION WAVELENGTH Light travels in the form of a wave. The wave is measure in terms of wavelength. The more waves which occur within a given distance, the shorter the wavelength is said to be. Each type (or frequency) of light displays different therapeutic benefits. The most common frequencies utiliized in phototherapy and in studies are Infrared and Visible Red Light. INFRARED The longest wave identified by a measurement and is invisible to the human eye. One wave occurs for every inch traveled by the infrared light. Infrared light penetrates to a depth of about 30-40 mm, which makes it more effective for bones, joints, deep muscles, etc. VISIBLE RED Shorter than infrared light with respect to wave length. For every inch the light travels, a wave and a half exist. Visible red light penetrates to a depth of about 8-10 mm -- it is very beneficial in treating problems close to the surface such as wounds, cuts, scars, trigger and acupuncture points and is particularly effective in treating infections. PULSATION FREQUENCY Pulsation frequency refers to the number of seconds the light (wavelength) is on and off (measured in Hertz, Hz). The usual duty cycle, often referred to as the Theta Range, means that the light is on for 1 second and off for 1 second. A higher frequency (faster pulsation) means the light is on for half a second and off for half of a second. Both add up to 2 seconds, but the light will be on/off more times at the higher frequency. It has been shown in studies that with a high-duty cycle, LEDs (like those used in the PainX 2000 products) provide a much gentler delivery of the same healing wavelengths of light, as does the laser, but at a substantially greater energy output. For this reason, LEDs do not have the same risk of accidental tissue damage that lasers have. |
