Infrared (IR) Light Therapy | Theory, Use, & Parameters

The video tutorial explores infrared light therapy, a therapeutic modality distinct from regular heat. It explains the light spectrum, focusing on infrared light's higher wavelength and lower energy, which allows it to penetrate skin without causing DNA damage. The video details how infrared light therapy works at the cellular level, enhancing wound healing and tissue repair through mechanisms like increased nitric oxide and ATP production. Various methods of delivering infrared light, such as lamps, pads, and probes, are discussed, highlighting their applications and precautions.

What distinguishes infrared light therapy from regular heat therapy?

• It uses sound waves instead of light.

• It operates at a higher temperature.

• It involves a different part of the light spectrum.

• It is visible to the human eye.

Which part of the light spectrum is associated with higher energy levels?

• Ultraviolet

• Red

• Near-infrared

• Infrared

Why is infrared light preferred over ultraviolet light in therapy?

• Infrared light is cheaper to produce.

• Ultraviolet light is not effective for therapy.

• Infrared light does not cause DNA damage.

• Ultraviolet light is not visible.

What is one method of delivering infrared light therapy?

• Ultraviolet lamp

• Infrared lamp

• Using a microwave oven

• Laser pointer

How does infrared light therapy accelerate wound healing?

• By cooling the affected area

• By increasing nitric oxide production

• By reducing blood flow

• By causing DNA mutations

What role do reactive oxidative species play in infrared light therapy?

• They cause chronic inflammation.

• They are harmful and should be avoided.

• They trigger beneficial protein activation.

• They reduce the effectiveness of the therapy.

Which transcription factors are activated by infrared light therapy?

• AP One and NF Kappa B

• DNA and RNA

• ATP and AMP

• Cyclic AMP and Nitric Oxide

What is a precaution to consider when using an infrared lamp?

• Avoiding direct contact with the skin

• Preventing skin burns by adjusting distance

• Using it for less than 5 minutes

• Ensuring the lamp is very close to the skin

How should an infrared light probe be used on the skin?

• In a linear motion

• In a static position

• In a circular motion

• In a zigzag pattern

What is the primary purpose of using red light in infrared therapy devices?

• To enhance the therapeutic effect

• To indicate the device is operational

• To increase energy levels

• To reduce treatment time
