Principles of Treatment of Sports Injuries There are five steps in the principles of treatment of sports injuries, including: Protection, Rest, Ice, Compression, and Elevation, which form a simple and easy-to-remember mnemonic from the beginning of these five single English words: “PRICE! “, so that we can easily learn how to properly deal with acute musculoskeletal injuries such as contusions, muscle strains, ligament sprains and other injuries. 1.P=Protection（Protection）：When injury occurs, the first principle of treatment is to protect the injured part and immobilize the injured part so as not to aggravate its degree of injury. 2, R = Rest (Rest): after the injury, to stop the activity of the injured part, if necessary, can use crutches to do appropriate support. Without the doctor’s examination and permission, should not be engaged in intense activities to avoid re-stimulation and make the injury worse, but also to promote recovery. 3, I = Ice (ice): to promote vasoconstriction, slow down the rate of blood circulation, and reduce the leakage of tissue fluid, in order to achieve the control of the injured part of the swelling, pain and spasm of the symptoms, because the degree of swelling of the injured part of the impact of the recovery of the length of time required. Commonly used ice packs will be crushed ice into a plastic bag or ice packs, and add a small amount of water, and the mouth of the bag tied tightly, is a simple ice pack; or with a wet towel wrapped in ice placed in the place where you want to ice. The production of simple ice bag: in the plastic bag or ice bag into the crushed ice, and add a small amount of water, and then the mouth of the bag tied tight. Handling: ①Place the ice bag on the skin of the injured area. ② Within 48 hours after the injury, ice packs every 2-3 hours, each ice time for 15-20 minutes. ③ Do not use the ice pack for more than 30 minutes at a time to avoid frostbite or nerve injury. 4, C = Compression (compression): elastic bandage wrapped in the injured area, do localized compression to reduce internal bleeding and tissue fluid exudation, also has the effect of controlling the swelling of the injured area. Note: ①When using the elastic bandage to do the wrapping compression, the pressure should be applied evenly in a spiral manner, and wrapped from the end of the limb to the proximal direction, when wrapped to the injured part can be slightly increased pressure. ② 60% to 70% of the maximum length of the elastic bandage can get enough pressure, the use of elastic bandage should always observe the injured toe or finger skin color, if there is pain, skin discoloration, tingling and other symptoms, said the elastic bandage is too tightly wound, should be unwrapped elastic bandage bandage re-wrapping. 5, E = Elevation (elevation): the injured part of the elevation (higher than the heart), to help accumulate in the injured part of the tissue fluid can flow back to avoid excessive swelling of the injured part. Can be implemented at the same time with ice, compression.
