Which is an example of thermotherapy?

• A. Ice massage
• B. Ultrasound
• C. Cold pack
• D. Whirlpool

Answer: (B)

Thermotherapy uses heat to raise tissue temperature, promoting blood flow, increasing tissue extensibility, and reducing pain and stiffness. Ultrasound fits this purpose because, when used in heating (continuous) mode, the sound waves are absorbed by tissues and converted into heat, providing a controlled deep heating effect that helps with tissue relaxation and healing. Ice massage and cold packs deliver cooling (cryotherapy), not heat, so they don’t provide the heating effects thermotherapy aims for. A whirlpool can be heated, but without specifying the water temperature, it isn’t an inherently clear example of thermotherapy. Ultrasound, with its well-established heating capability when used appropriately, is the best example of thermotherapy among the options.
