Which modality is commonly used in dry cryotherapy?

• A. Hydrocollator packs
• B. Ultrasound
• C. Heat lamps
• D. Ice bags

Answer: (D)

Dry cryotherapy centers on cooling tissue without moisture. Ice bags deliver cold by applying solid ice in a bag directly to the skin, giving a dry cold effect that reduces pain, swelling, and inflammation. The other options are heat-related or not used for cryotherapy: hydrocollator packs provide moist heat, heat lamps give heat, and ultrasound is a modality used for heating or tissue effects—not for cold therapy. So ice bags are the commonly used dry cold modality.
