The five-step process for treating an injury to a muscle or joint is called "P.R.I.C.E.", which is short for Protection, Rest, Ice, Compression, and Elevation).
It can be used even by someone without first-aid training, and should be used immediately when an injury occurs – the earlier, the better – while further medical attention is being sought.
If the athlete experiences too much pain during the process, stop immediately.
"P" is for Protection
Protect the injured person and the area being treated but also protect yourself. If the injury occurs on the sports field, stop the game.
Protect the area being treated with a splint if possible.
If the athlete can move, carefully move them to a safer area using a stretcher or a crutch, but if there is any doubt, do not move the injured athlete.
"R" is for Rest
When a child is injured, the body responds in an effort to defend, localize, protect, and clean up the injured area, a response called inflammation. At the time of injury small blood vessels at the injury site rupture and cause tissue bleeding, which, in turn, can cause bruising and swelling.
The five warning signs of inflammation are:
- Tissue hotness;
- Swelling, and
- Loss of function.
Note: not all kids swell or bruise, so even if there is no visible swelling or bruising, pain is an indicator of injury and means that rest is needed, and they should stop exercising immediately to avoid further damage.
"I" is for Ice
- As soon as possible after injury, begin applying ice continuously for the first 15-20 minutes to decrease swelling and pain.
- An ice bag can be applied directly to the skin (except on the outside of the knee) unless the child has a known cold allergy.
- The safest form of icing is to use a plastic bag with ice cubes or crushed ice, or instant cold packs. Do not use “blue ice” or “gel packs”.
- While icing will be uncomfortable at first, in 2 to 3 minutes, the skin will go numb and the ice bag will feel more comfortable. If the child continues to be very uncomfortable with ice being applied directly, then a barrier like a wet towel can be placed between the ice and skin.
- The ice bag can be secured in place using an elastic bandage, but the compression should not be too tight.
- During the application of the ice, ask the child to wiggle their fingers/toes and monitor tissue around area that is being iced to ensure that they are not experiencing a lost of sensation.
Icing for 15-20 minutes with an ice bag is unlikely to cause nerve damage or frostbite; however, any loss of sensation and any changes in tissue coloration in areas other than the area that is being iced indicate that the application is no longer safe.
Tip: Because ice and plastic bags are so important, make sure that someone brings these to every practice and game. Better yet, to be on the safe side, bring your own!
"C" is for Compression
- After icing, to further prevent swelling, wrap the injured area with an elastic bandage or compression sleeve.
- Take the wrap and start farthest away from the injured body part to the heart.
- Continuously wrap, always making sure to cover half of the previously wrapped area.
- As you get closer to the end of the wrap, you don’t need to wrap as tightly.
- You will know you have wrapped correctly when the hurt part ends up in the middle of the wrap.
- Tension should be firm but still comfortable. Tingling or pain means it’s too tight.
- Incorrect application of an elastic wrap could cause further pain and damage and delay healing.
"E" is for Elevation
For both upper and lower limb injuries, it is equally important to keep the limb elevated to minimize swelling. Elevation to the level of the heart or above allows for excess fluid to be pumped back into the blood vessel system and will help prevent further swelling from occurring.
Return to play
Not only is rest important in the period immediately after your child is injured, but adequate rest is necessary before your child returns to sports. Returning too soon from an injury can cause further damage and result in a chronic, long-term condition, such as chronic ankle instability, even permanent disability.
In addition to protection, rest, ice, compression, and elevation, restoring range of motion (ROM) is an important part of the recovery process when the swelling and pain begins to subside. Active ROM of an injured joint assists in introducing new blood flow to the injury site to "flush" out any residual cellular waste and joint edema present. Motion also assists in decreasing scar tissue and adhesion formation and stimulates the nervous system to begin activating the muscles that control strength, balance, and proprioception (position-movement sensation or body awareness) when return to play occurs. An athlete experiencing pain or swelling upon return to play or during rehab prior to play should seek the advice of a physician for further evaluation and/or diagnostic testing.
Return to play should ultimately depend on:
- pain-free, full range of motion;
- equal strength in the injured limb compared to the uninjured side;
- the absence of bruising and swelling;
- equal balance compared to the uninjured side (if it is a lower body injury); and
- no residual gait deficits (if a leg injury).
