RICE principles as an emergency treatment for ankle sprains, RICE principles have become classics: Rest: stop walking and let the injured part rest to reduce further damage; Ice: let the temperature of the injured part decrease to reduce the inflammatory response and muscle spasm, relieve pain and inhibit swelling. Apply ice for 10-20 minutes each time, more than 3 times a day, taking care not to apply ice directly to the affected area, but to wrap it in a wet towel to avoid frostbite. Compression: Wrap the injured ankle joint with an elastic bandage and apply appropriate pressure to reduce swelling. Elevation: Elevate the limb above the heart to increase venous and lymphatic return, reduce swelling, and promote recovery.
