Cryotherapy refers to which concept?

• A. The therapeutic use of cold; the application of a device or substance with a temperature less than body temperature, thus causing heat to pass from the body to the cryotherapy device.
• B. The application of heat to increase tissue temperature.
• C. Electrical stimulation to reduce pain.
• D. Ultrasound therapy to heat superficial tissues.

Answer: (A)

Cryotherapy is the therapeutic use of cold. By applying something cooler than body temperature to the body, heat flows from the body into the colder object, lowering the tissue temperature. This cooling reduces metabolic rate, causes vasoconstriction, slows nerve conduction, and helps decrease edema and pain. It’s distinct from heat therapies (which raise tissue temperature) and from modalities like electrical stimulation or ultrasound, which use different mechanisms. Examples include cold packs or ice massages.
