Cryotherapy is indicated for which condition?

• A. Chronic swelling
• B. Subacute muscle strain
• C. Acute swelling
• D. Healing of fractures without swelling

Answer: (C)

Cryotherapy works by cooling the injured tissue, which causes vasoconstriction, reduces capillary permeability, lowers metabolic demand, and slows nerve conduction. These effects help limit swelling, inflammation, and pain when inflammation is active. The scenario that fits best is acute swelling, because this is when the inflammatory process is underway and edema is accumulating. Cooling at this stage directly helps control that swelling and provides pain relief as part of the early management. In contrast, chronic swelling is less about active inflammation to be curbed with cold, and subacute injuries may have diminishing inflammation even though discomfort persists, so cold is less about primary indication. If there’s healing of fractures without swelling, there isn’t edema to address, so cryotherapy isn’t addressing the main issue here.
