Ankle Sprains Aren't "Just a Sprain": What the Research Says About Proper Rehab

Why "It's Just a Sprain" Is the Most Expensive Mistake You Can Make

You rolled your ankle stepping off a curb, playing pickleball, or coming down from a rebound. It swelled up, you iced it, you limped around for a week, and now it feels mostly fine. So you move on. That instinct is exactly why so many people end up needing ankle sprain treatment in Burlington months or even years later, often for a knee or back problem they never connected to the ankle in the first place. At Pursuit Physiotherapy, we see this pattern constantly, and the research backs up why it matters.

An ankle sprain is one of the most common injuries in active adults, and also one of the most undertreated. The culture around it is the problem: we treat sprains as innocuous, self-limiting, something you walk off. The data tells a very different story.

What Actually Happens When You Sprain Your Ankle

Most ankle sprains are lateral sprains, meaning the ankle rolls inward and overstretches or tears the ligaments on the outside of the joint. There are three grades, from a mild overstretch (Grade 1) to a partial tear (Grade 2) to a complete rupture (Grade 3).

But the ligament damage is only half the picture. Those ligaments are packed with sensors that tell your brain where your foot is in space, a sense called proprioception. When you sprain your ankle, you do not just damage tissue, you scramble that communication system. That is why a previously sprained ankle feels like it "gives way" unexpectedly, even after the swelling is long gone.

The Chronic Ankle Instability Trap

Here is the number that should make you take a sprain seriously: roughly 40% of people who sprain an ankle go on to develop chronic ankle instability. That means persistent feelings of giving way, recurring sprains, and an ankle that never quite feels trustworthy again.

And the consequences do not stay in the ankle. When your ankle is not moving or sensing properly, your body compensates up the chain, changing how you load your knee, hip, and lower back. Over time, those compensations create problems of their own. We treat a lot of patients across Burlington and Oakville for knee and hip pain that, when we trace it back, started with an ankle sprain nobody rehabbed properly.

What the Research Says About Skipping Rehab

A large 2022 study followed more than 33,000 people after an ankle sprain to see what happened over the following year. The findings are hard to ignore.

One in five patients (20.5%) who sprained an ankle went on to suffer a subsequent injury to their knee, hip, or lower back within 12 months. Yet only 28% were prescribed any rehabilitation exercise after the original sprain. The patients who did get proper exercise rehab had a 13% lower risk of a subsequent knee injury, an 18% lower risk of a lumbar spine injury, and a 32% lower risk of a hip injury.

Read that again. Doing the rehab cut the risk of a future hip injury by nearly a third. The study's authors put it plainly: effective rehabilitation has to progress beyond the injured ankle to address the joints above it and retrain whole-body movement. A few days of rest and ice does not do that.

This is the core problem with the "walk it off" approach. The pain settles, so you assume you are healed, but the strength, balance, and proprioception deficits are still there, quietly raising your risk of the next injury.

How Physiotherapy Treats Ankle Sprains in Burlington

Proper ankle sprain rehab is not complicated, but it does need to be structured and progressed. When you come into our clinic, treatment generally works through a few overlapping phases.

Early phase: protect and restore movement

In the first days to weeks, the goal is to control swelling, protect healing tissue, and gently restore range of motion. Hands-on manual therapy can help reduce stiffness and get the joint moving again without aggravating the injury.

Strength and balance phase

This is where most self-treated sprains fall short. We use targeted exercise prescription to rebuild the muscles that stabilize the ankle and, just as importantly, to retrain the proprioception that the sprain disrupted. Single-leg balance work, controlled hopping, and progressive loading all rebuild that "trust" in the joint.

Return to activity phase

For athletes and active people, the final phase bridges the gap between feeling okay and being ready to cut, jump, and change direction with confidence. Our sports injury rehabilitation approach uses functional testing to make sure your ankle, knee, and hip are all ready before you return to your sport, not just your pain level.

Throughout all of it, we are not only looking at the ankle. Because the research is so clear that ankle sprains drive injuries up the chain, we assess and load the knee, hip, and trunk too. That is the difference between rehab that gets you out of pain and rehab that keeps you out of the next clinic visit.

What to Expect at Your First Appointment

Every assessment at Pursuit is one-on-one with a physiotherapist for the full session, not a quick look before being handed off to a machine. Javier will take a proper history, test the ankle's range, strength, and stability, screen the joints above it, and watch how you move. From there you get a clear explanation of what is actually going on and a plan built around your goals, whether that is getting back to running in Bronte, hiking around Waterdown, or just walking the dog without thinking about it.

What You Can Do Right Now

If you are in the early days after a sprain, a few sensible steps help:

• Keep gently moving it. Within comfortable limits, early movement beats total rest for most sprains. Tracing the alphabet with your big toe is a simple way to keep the ankle mobile.

• Load it progressively. Walking on it as pain allows is usually fine and helps recovery, as long as you are not pushing into sharp pain.

• Start balance work early. Once you can stand on the foot comfortably, practice single-leg balance for 30 seconds a few times a day. This is one of the most important and most skipped parts of recovery.

• Do not rely on a brace forever. A brace can help in the short term, but it is not a substitute for rebuilding strength and balance.

These are starting points, not a full program. The strengthening and proprioception work that actually lowers your re-injury risk needs to be matched to your specific deficits.

When to See a Physiotherapist

You should get an ankle sprain assessed if any of these apply: you could not bear weight on it right after the injury, the swelling and pain are not steadily improving after a week or two, the ankle keeps giving way or you have sprained it before, or you want to return to a sport with confidence. And honestly, even a "minor" sprain is worth a single visit, because the whole point of the research above is that the minor ones are the ones people ignore until they become something bigger.

We treat patients from across Burlington, Millcroft, Aldershot, Oakville, Hamilton, and Milton, and ankle sprains are one of the most satisfying things to rehab properly because the results are so clear.

Ready to get to the root of it?

If you have rolled your ankle, or you have one that has never felt right since, book a one-on-one assessment with physiotherapy at Pursuit. We will get you moving well and lower your risk of the next injury, not just the current one.
