What is the purpose of cryotherapy in relation to inflammation, swelling, or edema?

• A. To prevent or slow down, not remove
• B. To eliminate edema completely
• C. To increase metabolic rate
• D. To raise tissue temperature

Answer: (A)

Cryotherapy aims to blunt the inflammatory process and limit edema by lowering tissue temperature, which slows cellular metabolism and causes vasoconstriction. This reduces blood flow and capillary permeability, helping prevent excess fluid from accumulating in the injured area. Because cold slows progression rather than instantly removing all swelling, the goal is to prevent or slow edema formation, not to eliminate it completely. It does not raise tissue temperature; it lowers it, and it does not increase metabolic rate.
