Which option represents a cold-based intervention in edema management?

• A. Ultrasound
• B. Cold therapy
• C. Heat therapy
• D. Massage

Answer: (B)

Controlling swelling in edema relies on cooling the affected area to limit fluid accumulation. Cold therapy achieves this by causing vasoconstriction and reducing capillary permeability, which lowers fluid leakage into the tissues and helps reduce edema in the acute phase. It also decreases metabolic activity and inflammatory mediator activity, aiding pain and swelling control. In practice, cold therapy includes ice packs or other cooling methods. The other options aren’t cold-based: ultrasound isn’t inherently a cold modality and can be used for heating or non-thermal effects; heat therapy increases blood flow and can worsen edema; massage helps move fluid but isn’t a cold-based intervention.
