Which of the following is a type of cryotherapy?

• A. Ice massage
• B. Infrared lamp
• C. Cold bath
• D. Cold pack

Answer: (A)

Cryotherapy means using cold to lower tissue temperature and slow nerve activity to reduce pain, swelling, and tissue metabolism after an injury. Ice massage fits this, because it applies a solid block of ice directly to the skin to rapidly and locally cool superficial tissues. That direct, controlled cooling is what produces quick analgesia and helps limit edema in the acute phase. An infrared lamp, by contrast, emits radiant energy that warms tissue rather than cools it, so it isn’t cryotherapy. Cold baths and cold packs are also cooling methods and are considered cryotherapy too, but ice massage is a classic direct-contact technique that provides precise, brief cooling to a targeted area, which is why it’s categorized as a type of cryotherapy.
