What is cryotherapy?

• A. A heating technique
• B. A method of injecting contrast
• C. A type of radiation therapy
• D. A therapy modality that causes blood vessels to constrict and reduces swelling and pain

Answer: (D)

Cryotherapy uses cold to affect body tissue. Applying cold causes blood vessels in the area to constrict (vasoconstriction), which reduces blood flow, edema, and swelling. The cold also slows nerve conduction and lowers metabolic activity, helping to decrease pain and inflammation after an acute injury. This is distinct from heating methods (thermotherapy), contrast injection for imaging, or radiation therapy. So the option describing a therapy modality that causes blood vessels to constrict and reduces swelling and pain accurately captures what cryotherapy does.
