An example of light therapy is:

An example of light therapy is:

• A. Laser
• B. Ultrasound
• C. Whirlpool
• D. Tens unit

Answer: (A)

Light therapy delivers energy to tissues using light. An example of this is laser therapy, which emits a focused beam of light at specific wavelengths. That light is absorbed by cellular components, such as mitochondrial chromophores, and can boost cellular energy production, reduce inflammation, and promote tissue repair. These effects can translate to pain relief and faster healing. The other options use different types of energy: ultrasound uses high-frequency sound waves to produce mechanical effects and heating; whirlpool relies on warm water and agitation as hydrotherapy; a TENS unit delivers electrical stimulation to nerves to modulate pain. Because laser therapy is a direct application of light energy to the tissue, it fits the category of light therapy.
