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

• A. To prevent or slow down, not remove
• B. To completely eliminate edema
• C. To increase swelling
• D. To heat the tissue

Answer: (A)

Cryotherapy works in acute inflammation by cooling the tissue, which slows metabolic activity and causes vasoconstriction. This reduces blood flow to the area and lowers capillary permeability, so less fluid leaks into the interstitial space. By dampening the inflammatory cascade early on, swelling is prevented from getting worse and progresses toward resolution more quickly. It’s not about instantly eliminating edema; edema may still be present, but the goal is to prevent its progression and limit tissue damage. Heating the tissue would increase blood flow and swelling, which is the opposite effect.
