Which modality is included with cold packs as a standard option for analgesia?

• A. TENS
• B. Ultrasound
• C. Heat/cold packs
• D. Cryotherapy only

Answer: (B)

Cold therapy provides analgesia primarily through cryotherapy, which lowers tissue temperature to slow nerve conduction, reduce local inflammation, and lessen pain. A standard option that comes with cold packs is the cryotherapy effect itself—the cold stimulus delivered by the pack. Ultrasound, by contrast, is a separate modality that requires its own device and settings and is not typically bundled with cold packs as a standard analgesic option. Some products pair heat and cold packs, but the cold component remains cryotherapy, not ultrasound. So the concept being tested is that the analgesic effect associated with cold packs comes from cryotherapy, not from ultrasound.
