FAQs: Polychromatic Light Therapy
Here are the answers to some of the most common questions about light therapy and InLight Medical systems, from light users just like you.
Q: What is light therapy?
A: Low-level light therapy (LLLT) stimulates the process called photobiomodulation (PBM). In scientific studies, PBM has been shown to trigger the release of nitric oxide (NO). NO causes local vasodilatation which causes an increase in local circulation bringing increased oxygen and glucose to tissue. The release of NO by the mitochondria unlocks the aerobic metabolism of the mitochondria allowing them to produce Adenosine Triphosphate (ATP). ATP is the major energy currency of the cell.
Q: What is the difference between red, blue and near-infrared (NIR) light?
A: Each wavelength penetrates to a different level of tissue. InLight Medical’s pads include two to three wavelengths on each pad with respective penetration depths as follows:
- Blue & Near-Infrared (NIR) Light: Increases circulation and reduces pain. Blue (465nm) penetrates ~3mm. NIR (850nm) perpetrates ~100mm. This provides a superficial and deep light wavelength penetration.
- Red & Near-Infrared (NIR) Light: Increases circulation and reduces pain. Red (629nm) penetrates ~10mm. NIR (850nm) perpetrates ~100mm. This provides a mid and deep light wavelength penetration.
- Various combinations of these three lights create the InLight Medical low-level Polychromatic Light Therapy system. Research1 has shown it’s beneficial to utilize the power of multiple wavelengths (polychromatic) of light to stimulate the body with photobiomodulation and warmth.
Q: What is “polychromatic” light therapy?
A: Polychromatic light therapy is the simultaneous use of more than one light wavelength, or color. InLight Medical Systems™ use two or more light wavelengths in every pad.
Q: What is Progressive Multi-Pulse™ technology & how is it different from other systems?
A: InLight systems are engineered to automatically pulse light through seven different frequencies (Hz) during each 20-minute session when placed on setting A, B, or C to provide photons to the body in a variety of cycles.
Q: What has light therapy been shown to do?
A: INCREASE CIRCULATION: Circulation is increased by the release of nitric oxide which causes both local vasodilatation and the formation of new capillaries. Increased circulation may result in carrying more oxygen and glucose to the tissue.
REDUCE PAIN: LLLT has been shown in scientific studies to release nitric oxide which causes local vasodilatation which improves the oxygenation of ischemic tissue to reduce pain. It also triggers the nucleus of the cell in a process called photobiomodulation, to manufacture various natural, cellular substances, including anti-inflammatories, which may also reduce pain.
STIMULATE THE PRODUCTION OF ADENOSINE TRIPHOSPHATE (ATP): ATP is the major energy currency in all cells which allows them to function. ATP provides the chemical energy that supports most chemical reactions within the cell. The release of NO (an inhibitor in the cell) by LLLT unlocks the aerobic metabolism of our mitochondria allowing them to produce more ATP which allows the cell to function more freely without the NO inhibition to mitochondria.
Q: Why are there only three wavelengths used?
A: While the sun’s light is “full spectrum” and essential for life, the bulk of current medical research is focused on the wide range of wavelengths within the red, blue and infrared spectrums.
Q: What are the differences between each program setting?
A: InLight controllers are designed with proprietary Progressive Multi-Pulse™ Technology, providing state of the art delivery of the polychromatic light. The automatic settings A, B, and C contain a diverse combination of the Progressive Multi-Pulse™ Technology frequencies.
Q: What are the settings and numbers for?
A: The systems come with Cycles and Manual Settings (1-7). The cycles rotate through up to seven pulse frequencies of light. The manual settings, 1 – 7, are simply different frequencies or rates of pulsing of light in cycles/seconds or Hertz.
Q: Why are there different pad shapes?
A: InLight has listened to their customers and designed the flexible neoprene pads shape to fit body areas more comfortably.
Q: Why are some of the lights on InLight Medical devices dark?
A: The “dark” rows on InLight devices are the rows of near-infrared diodes. Near-infrared wavelengths are just outside of the human visible color spectrum.
InLight has included an near infrared spectrum emission tester on the top of the 6/Port controller. By placing a near infrared LED above the circular testing dot to the right of the LCD screen of the 6/Port, the tester will provide feedback by means of illuminating a green LED on the back of the controller if it senses near infrared light. Some new digital cameras may also pick up near infrared wavelengths and display them as lighted.
Q: Are the pads safe to use on animals?
A: We have received stories and photos of customers using the devices on animals. LED light therapy has been shown to be effective for canine pain therapy, and for reliving pain and healing injuries in sport horses.
Please consult with your pet or animal’s attending veterinarian to determine safe and effective use of medical devices with the animal’s healthcare treatment.
Q: Do I have to use a specific pad on a specific part of my body?
A: No. While some pads are designed to fit certain parts of the body better than others, any LED light therapy pad can be used on any part of the body.
Q: How long should I use my light pads?
A: The InLight Medical System controllers are built with an automatic shut-off timer for 20-minute applications.
InLights’ unique Progressive Multi-Pulse™ Technology allows for multiple daily applications. We recommend not exceeding 60 minutes of application to an area in a 24-hour period.
Q: How do I use the pads?
A: Using your system is as simple as placing the PLT pads light side-down against the skin of the target area and turning the controller on. Pads can be moved and repositioned during the 20-minute session as needed.
Q: How do I clean the pads?
A: As a Non-Critical medical device as it pertains to disinfection and sterilization, the device is recommended only for use topically on unbroken and clean skin. Routine care and maintenance can be performed by using a disinfectant wipe to clean the LEDs and neoprene pad or follow your facilities protocols for the treatment of non-critical items.
In a Semi-critical exposure case, when applying the pads to a topical area of concern for infection (open wounds), use a clear plastic barrier between the pad and the potentially infectious site to prevent pad soiling. In all cases, disinfection of the system can be performed regularly with hospital grade disinfectant solution (1:10 bleach solution). Spray solution onto a cloth and lightly wipe device clean with cloth. Do not soak, saturate or submerge device in liquid. Do not autoclave.
Q: I have a 6/PORT PRO controller. What does the “SOUND” button do?
A: The SOUND button enables you to choose between having a silent timer countdown or have a beeping to notify you of when the 20-minute session is complete.
