'It's only a sprain.' But what does that really mean?

Advice on treating your child’s sprained ankle

At some point in time we have probably all seen a sporting event where an athlete goes down with an ankle injury. In a lot of those cases we have probably also heard the commentators or someone at the event say “Hopefully it’s only a sprain.” While other injuries may be more severe, looking at it as “only a sprain” may not be giving the injury the attention it deserves.

As parents before we just shrug off our children’s injury as nothing too serious, it helps to know exactly what a sprain is.

The American Academy of Orthopedic surgeons define a sprain as a stretch and/or tear of a ligament, the fibrous band of connective tissue that joins the end of one bone to another.

Technically a torn ACL or a torn MCL in the knee is a sprained knee, but we never shrug those injuries off. So why are we so dismissive of ankle sprains? Admittedly a sprained ankle is typically not as severe of an injury as a torn ACL, because an ACL when torn will not heal on its own and requires a surgical reconstruction, but that is a topic for another blog.

Just as with any injury when dealing with an ankle sprain we need to start by determining the severity of these injuries. Ankle sprains are typically divided into three grades based on the severity and presentation of the injury.

Grade 1: Ligaments are stretched, but not torn, ligaments are tender to touch, but no laxity is noted, and the patient is able to walk with little to no pain.

Grade 2: Ligaments are stretched and at least partially ruptured, there is moderate pain and swelling, mild to moderate bruising, some range of motion loss, the patient has pain with walking, and there is mild to moderate laxity noted.

Grade 3: Ligaments are completely torn, there is severe swelling, severe bruising, significant loss of motion, the patient is unable to bear weight or walk on the ankle, and there is significant laxity noted.

The severity of the sprain will definitely influence how we treat these injuries.

So why is it important for my child to rehab an ankle sprain?

The number one predictor of ankle injuries is a previous ankle injury. So what this tells me is that more often than not we aren’t addressing that initial injury effectively. Each ligament sends information to the brain letting us know if our joints are in good alignment or not. This is why we don’t have to look at our feet when we walk to know that our foot is in a good position to take a step. Any time a ligament is torn or stretched we lose some of our awareness of where the joint is in space. If a ligament is completely torn or stretched we aren’t getting those signals until our joint is potentially already in a bad position. After injury we have to do something to make sure that we re-establish that joint awareness, and that is where Physical Therapy comes in.

How can physical therapy help my child recover from an ankle sprain?

Initial focus in physical therapy will reduce swelling and inflammation with RICE (rest, ice, compression, and elevation), and regaining ROM. While this first phase is very important, the portion of rehab that really helps to prevent recurring injuries is the strengthening and proprioceptive (or balance) training. The balance exercises are the exercises designed to retrain joint position awareness by training the muscles to recognize and stabilize where our joint is in space. The balance and strengthening exercises are what will truly help a patient return to higher level activities like jumping and cutting in sports.

When do I get help for my child who has an ankle sprain?

  • Any time an injury causes notable laxity or instability on exam.
  • Any time a patients is unable to walk without pain.
  • Any time balance is negatively affected.
  • That means grade 2 sprains and above should automatically get help and any grade 1 sprain with balance deficits should also do rehab. If there is ever any doubt, error on the side of caution and contact your physician.

At Cook Children’s, our SPORTS physical therapists are trained in proper rehabilitation of all grades of ankle sprains and work to restore full function and safely guide return to athletic activities. If your child has a history of frequent ankle sprains or you are concerned about risk of future injury, talk to your doctor about a referral to physical therapy.
