Which of the following is an indication for cryotherapy?

• A. Improve appetite
• B. Increase bone density
• C. Reduce inflammation
• D. Increase muscular hypertrophy

Answer: (D)

Cryotherapy is used to manage inflammation and pain after an acute injury by cooling the tissues. By lowering tissue temperature, it causes vasoconstriction, reduces metabolic demand, dampens inflammatory mediator activity, and slows nerve conduction, all of which help decrease swelling and associated pain. Because of this cooling effect, the primary indication among the options is reducing inflammation. It won’t purposefully improve appetite, increase bone density, or promote muscular hypertrophy—those outcomes come from nutrition, mechanical loading, and progressive resistance training, not cold therapy.
