Cryotherapy is indicated for which of the following conditions?

• A. Acute or subacute inflammation
• B. Osteoarthritis
• C. Chronic fatigue
• D. Chronic skin infection

Answer: (A)

Cryotherapy reduces tissue temperature to blunt the inflammatory process, making it most appropriate during acute or subacute inflammation. The cold causes vasoconstriction, lowers metabolic rate, and decreases nerve conduction velocity, which together reduce swelling, limit inflammatory mediators, and lessen pain. These effects are most beneficial in the early phases after injury when inflammation and edema drive pain and tissue damage risk. While cold can provide symptomatic relief for some chronic conditions, it is not the primary indication for a chronic process like osteoarthritis, and it isn’t aligned with the mechanisms underlying chronic fatigue or chronic skin infection. So the best fit is acute or subacute inflammation.
