Cryotherapy-induced vasoconstriction primarily Relieves mechanical compression due to edema around which structures?

• A. Nerves and vascular structures
• B. Bones
• C. Muscle fibers
• D. Skin

Answer: (A)

Cryotherapy causes vasoconstriction, which lowers blood flow and limits the inflammatory response, thereby reducing edema formation. When swelling occurs, it can mechanically compress nearby soft-tissue elements, especially neural and vascular bundles. Reducing edema around these structures relieves pressure on nerves and blood vessels, helping restore conduction and perfusion and decreasing pain. Bones are rigid and edema around them doesn’t produce the same compressive effect, and skin edema is more superficial. The clinically meaningful relief from edema-related compression is most notable around nerves and vascular structures.
