What is the typical duration for cryotherapy and its continuation period after injury?

• A. 5 to 10 minutes, once daily.
• B. 20 to 30 minutes, several times a day.
• C. 60 minutes every hour.
• D. 2 to 3 minutes every 2 hours.

Answer: (B)

Cryotherapy works by cooling the injured tissue to reduce blood flow, swelling, and pain, so the duration is kept long enough to produce meaningful cooling without risking skin or tissue damage. A typical approach uses cold applications for about 20 to 30 minutes per session, and these sessions are repeated several times a day during the acute phase. Doing this frequently—for example every couple of hours—helps maintain the cooling effect over the first day or two (often the first 24 to 72 hours), then the frequency is gradually tapered as symptoms improve. This balance avoids under-cooling, which won’t help swelling, and over-cooling, which could cause frostbite or nerve irritation. Remember to place a cloth or barrier between the skin and the cold source and to stop if numbness, color change, or increased pain occurs.
