Ankle Sprains: When to See a Physiotherapist, and Why Walking It Off Backfires

Written by Nicolas Marchant, Registered Physiotherapist. Before founding PhysioHome, I worked as a physiotherapist with Vancouver Coastal Health, where ankle sprains arrived in two forms: the fresh injury from the night before, and the ankle that had been quietly giving way for three years because the first sprain was never rehabilitated.

An ankle sprain is a tear in a ligament, and the single strongest risk factor for spraining an ankle is having sprained it before. That is the part most people miss. The swelling settles in a couple of weeks whether you do anything or not, so the injury feels finished long before the ankle is actually reliable again.

Late autumn in Metro Vancouver is when the volume climbs. Wet leaves on sidewalks and stairs, dark commutes, and the first weekends on the North Shore mountains all produce the same mechanism: the foot rolls inward under a body still moving forward.

What Is Actually Injured

Most ankle sprains are lateral sprains: the foot rolled inward and the ligaments on the outside of the ankle were overstretched or torn.

Two less common patterns matter because they behave differently and are frequently missed:

High ankle (syndesmotic) sprains, where pain sits above the joint between the two shin bones rather than below the ankle bone. These take considerably longer to recover and are worse with pushing off and twisting.
Medial sprains, on the inside of the ankle, which often accompany a more significant injury.

A sprain is also not only a ligament problem. It disrupts the position sense that tells your brain where your foot is in space, which is why a previously sprained ankle can feel untrustworthy on uneven ground long after the pain has gone.

First: Do You Need an X-ray?

Swelling and bruising do not tell you whether something is broken: severe sprains swell dramatically and some fractures barely swell at all.

Emergency clinicians across Canada screen for this with the Ottawa Ankle Rules, a validated decision tool. Imaging is indicated when there is ankle or midfoot pain together with any of the following:

Bone tenderness along the back and lower edge of either shin bone, or at the tip of the inner or outer ankle bone
Bone tenderness at the navicular (the bony bump on the inside arch) or at the base of the fifth metatarsal (the bony bump on the outside edge of the foot)
Inability to take four steps, both at the time of injury and when assessed

When none of those are present, the probability of a clinically significant fracture is low, with reported sensitivity of roughly 96 to 99 percent for ruling fracture out. A negative result does not mean the ankle is fine, though. It means the bone is probably intact and the injury is in the soft tissue, which is what rehabilitation is for.

If you meet any of those criteria, get assessed medically before starting rehab: a walk-in clinic, urgent care, or the emergency department at Lions Gate, Vancouver General, Burnaby Hospital, Royal Columbian, Eagle Ridge, Surrey Memorial, or Richmond Hospital, depending on where you are.

What the Evidence Supports

The reference standard here is the 2021 lateral ankle sprain clinical practice guideline published in the Journal of Orthopaedic and Sports Physical Therapy by Martin and colleagues. For an acute or recently acute sprain, it reports strong to moderate evidence for four things: protection with appropriate loading, manual therapy, exercise directed at the specific impairments found on assessment, and progressive retraining toward your actual work or sport.

Three practical points follow from that.

Rest is protection, not treatment. Current guidance favours early controlled loading over prolonged immobilisation for most sprains, so walking within comfort, often with support initially, generally beats waiting it out. Ice and elevation are reasonable for comfort early on, but they are symptom management, not recovery.

Balance and position sense training is the part that prevents the next one. The same guideline cites a meta-analysis in which balance training significantly reduced the risk of a recurrent sprain (odds ratio 0.59, 95 percent confidence interval 0.51 to 0.68). A systematic review it draws on found that completing at least six weeks of balance training after an acute sprain substantially lowered recurrence risk. This is the single most skipped element of ankle rehab and the one with the clearest payoff.

Strength has to extend past the ankle. Assessment looks at hip and knee control during single leg tasks, because how the whole limb controls landing and turning determines whether the ankle is put in a vulnerable position again.

For an ankle unreliable for a year or more, which the guideline classifies as chronic ankle instability, the evidence points to proprioceptive and neuromuscular exercise plus graded joint mobilisation. An old sprain is still treatable.

Red Flags: See a Doctor or Emergency Care

Get medical assessment rather than starting rehabilitation if you have:

Any of the Ottawa criteria above, particularly inability to take four steps or bone tenderness over the points described
Obvious deformity of the ankle or foot, or a joint that looks out of position
Numbness, pins and needles, or a foot that is cold, pale or dusky, which needs urgent assessment
Pain severe and out of proportion, or a tense, rapidly swelling lower leg
Fever, spreading redness or heat, which may indicate infection
A painful, swollen, warm calf, or new chest pain or breathlessness, which can indicate a blood clot
An injury in a child or teenager, because growth plates are injured in ways adult ligaments are not
No meaningful improvement after about two weeks, or an ankle that keeps giving way
A fall that caused the sprain in an older adult, where the fall itself needs explaining and bone health matters. Low bone density changes the fracture picture, and our guide to safe exercise with osteoporosis covers that side of it.

Why an In-Home Assessment Works Well Here

A fresh ankle sprain is the definition of an injury that makes travel difficult, and walking from a parking lot to a clinic on an ankle you cannot load properly is the worst part of the appointment.

Seeing you at home also means we assess what you actually have to manage: your stairs, the step at your back door, the distance to the bus, using what is already in your home rather than equipment you do not own.

We serve Greater Vancouver, including Vancouver, North and West Vancouver, Burnaby, New Westminster, Coquitlam, Port Coquitlam, Port Moody, Surrey, and Richmond. Sprains from recreational activity usually sit within our sports injury rehabilitation approach, and for older adults where the sprain came from a fall, our physiotherapy for seniors covers the balance and confidence side as well as the ankle.

Fees and Billing

A 45 minute in-home visit is $180 and a 60 minute visit is $210. Kinesiology and rehabilitation assistant visits start at $130, which suits the later balance and strengthening phase once a physiotherapist has set the plan. Current rates are on our fees page.

Ankle sprains are usually billed privately or through extended health benefits, and most BC plans cover physiotherapy up to an annual limit. ICBC and WorkSafeBC claims are handled separately and apply only to a motor vehicle incident or a workplace injury.

Frequently Asked Questions

How long does an ankle sprain take to heal?

Mild sprains often settle within two to four weeks, and more significant ones take longer. Being pain free is not the same as being recovered: position sense and strength usually lag behind comfort, which is why sprains recur after people feel ready.

Should I keep weight off it?

For most sprains, no. Current guidance favours protected early loading over prolonged rest, which usually means walking within comfort, with support if needed. If you cannot take four steps, get assessed medically first to rule out a fracture.

Do I need an X-ray for every sprain?

No. The Ottawa Ankle Rules exist precisely to avoid unnecessary imaging. If you have no bone tenderness at the specific points and can take four steps, a fracture is unlikely and imaging usually adds nothing.

My ankle has been weak since a sprain years ago. Is it too late?

No. Persistent giving way is classified as chronic ankle instability, and the 2021 guideline supports proprioceptive and neuromuscular exercise with graded joint mobilisation for it. People commonly improve years after the original injury.

Do I need a doctor's referral to see a physiotherapist?

No. Physiotherapy is direct access in British Columbia, so you can book without a referral. Some extended health plans ask for one before reimbursement, so check your policy.
