Cold therapy is used for acute injuries because it promotes which effect?

• A. Promotes Vasodilation
• B. Increases Blood Flow
• C. Promotes Vasoconstriction
• D. Increases Warmth

Answer: (C)

Cold therapy works by causing vasoconstriction of the superficial blood vessels. This reduces blood flow to the injured area, helping limit swelling and secondary tissue damage that can occur in the acute phase. It also lowers tissue metabolism and slows nerve conduction, contributing to pain relief. So the effect promoted by cold therapy in acute injuries is vasoconstriction. Vasodilation, increased blood flow, and warmth are opposite effects that would not help in the acute setting.
