Ankle Sprain Physiotherapy · Bukit Timah, Singapore
Ankle Sprain Physiotherapy
A rolled or twisted ankle is one of the most common sports injuries there is — but it's also one of the most under-treated. Studies suggest as many as 1 in 5 people go on to develop chronic ankle instability after a single sprain, and correctly-graded rehab is the single biggest factor in preventing that.

What Is an Ankle Sprain?
An ankle sprain is an injury to one or more of the ligaments that hold the ankle joint together — bands of tissue that stabilise the joint by limiting how far it can roll or twist. Around 85% of ankle sprains are lateral sprains, where the foot rolls inward and the ligaments on the outside of the ankle (most often the anterior talofibular ligament, or ATFL) are stretched or torn.
It typically happens from a fall, a sudden twist, landing awkwardly from a jump, or stepping on an uneven surface. It's genuinely one of the most common injuries in sport — and also one of the most commonly under-managed, since the "it's just a sprain, walk it off" attitude is exactly what allows a large share of sprains to become a recurring, long-term problem.
How Ankle Sprains Are Graded
Severity is classified by how much ligament damage has occurred. This grading guides — but doesn't dictate on its own — how your rehab is structured.
Grade I — Mild
A stretch to the ligament with little to no tearing. Minimal swelling, no real joint instability, usually still able to bear weight.
Grade II — Moderate
Partial tearing of the ligament, with mild to moderate instability. Noticeable swelling and bruising, and weight-bearing is usually painful.
Grade III — Severe
Complete rupture of one or more ligaments, with significant instability. Substantial swelling and bruising, often across both sides of the ankle, and weight-bearing is typically very difficult.
Do I Need an X-Ray?
Most ankle sprains don't need imaging — the diagnosis is usually made clinically. To decide when an X-ray is actually warranted, clinicians commonly use the Ottawa Ankle Rules, a validated clinical decision tool. An X-ray is generally indicated if:
- There's bone tenderness along the back edge or tip of either ankle bone (malleolus)
- There's bone tenderness at the base of the fifth metatarsal or the navicular bone in the foot
- You're unable to bear weight — both immediately after the injury and at assessment — for at least four steps
If none of these apply, imaging is unlikely to change your management, and we can usually proceed straight to treatment. If they do apply, we'll refer you appropriately before starting rehab.
Evidence-Based Treatment
For decades, the default advice for a sprained ankle was to immobilise it in a cast or rigid brace for weeks. The evidence has moved on from that. A 2025 systematic review and meta-analysis found physiotherapy-led functional treatment produced significantly better pain outcomes than immobilisation for grade I and II acute sprains. Current clinical guidelines reflect this: a short period of protection for comfort in the first few days is reasonable, but functional treatment — a supportive brace or tape combined with a structured exercise programme — is what the evidence actually supports for most sprains, not prolonged immobilisation.
Accurate Grading & Assessment
Confirming the grade of injury and ruling out associated damage — a high ankle sprain (syndesmotic injury) or fracture needs a different approach entirely.
Early Protection, Brief
In the first few days, managing swelling and pain — protecting the joint, elevation, and appropriate compression — while avoiding the extended immobilisation that delays recovery.
Restore Range of Motion
Gentle, progressive movement work to regain the ankle's full range as swelling allows — stiffness left unaddressed here tends to linger.
Proprioception & Balance Retraining
This is the piece most often skipped after a sprain — and the single biggest factor in whether the ankle becomes unstable long-term. A sprain damages not just ligament but the nerve receptors that give your brain positional feedback about the joint; balance and proprioceptive exercises retrain that.
Strength & Graded Return to Sport
Rebuilding calf and ankle stabiliser strength, then progressing through sport-specific movement — cutting, jumping, landing — before a full return to play.
Why Proper Rehab Matters: Preventing Chronic Instability
This is the part that makes a proper rehab programme worth prioritising over "resting it and hoping." Estimates vary across studies, but a reasonably well-supported figure from Cochrane review data is that 10 to 20% of people who sprain an ankle go on to develop chronic ankle instability — recurring giving-way, a persistent feeling of unreliability in the joint, and repeat sprains, sometimes for years afterward. Other studies report considerably higher rates of ongoing symptoms depending on how "chronic" is defined and how long people are followed up.
The mechanism is well understood: a previous ankle sprain is consistently the strongest known predictor of a future one, largely because the proprioceptive and neuromuscular deficits a sprain causes don't resolve on their own without targeted rehab. This is precisely why the balance-and-proprioception phase of treatment isn't an optional add-on — skipping it is one of the most common reasons a "minor" sprain turns into a recurring problem.
How Long Does Recovery Take?
Recovery time depends heavily on the grade of injury:
- Grade I: Typically 1 to 3 weeks before returning to normal activity
- Grade II: Generally 3 to 6 weeks, with a graded return to sport built in
- Grade III: Often 6 to 12 weeks or longer, and occasionally requires orthopaedic input if instability persists
These are general guides, not guarantees — how consistently you follow the balance and strengthening phases matters just as much as the grade itself in determining both how fast you recover and whether it stays resolved. We'll give you a timeline specific to your presentation at assessment.

Ankle Sprain FAQ
Should I rest a sprained ankle completely, or keep moving it?
A short period of protection for comfort in the first few days is reasonable, but the current evidence favours functional treatment — a supportive brace or tape paired with early, guided movement — over prolonged immobilisation for most sprains. Complete rest for weeks tends to leave the joint stiffer and the surrounding muscles weaker, without actually improving the outcome.
Do I need crutches or a boot?
It depends on the grade of injury and how much weight you can comfortably bear. Milder sprains usually don't need either. More significant sprains may benefit from a short period of supported weight-bearing, but this is assessed individually rather than applied as a default.
Why does my ankle still feel unstable months after it stopped hurting?
This is a genuinely common pattern, and it usually means the proprioceptive and strength deficits from the original sprain were never fully addressed — pain resolving doesn't automatically mean the joint's stability and positional control have fully recovered. This is exactly what the balance and strengthening phase of rehab is meant to prevent, and it's worth addressing even if the injury happened a while ago.
Should I tape or brace my ankle every time I play sport now?
For a period after a sprain, or if you have ongoing instability, external support like taping or a brace is genuinely useful and evidence-supported. Long-term, the goal is to build enough strength and proprioceptive control that you're not solely reliant on it — but for some people with recurrent instability, ongoing use during high-risk activity is a reasonable, practical choice.
How do I know if it's a sprain or something more serious, like a fracture?
Signs that warrant an X-ray include bone tenderness directly over either ankle bone or specific spots in the foot, and being unable to take four steps immediately after the injury or at assessment (the Ottawa Ankle Rules). If none of these apply, imaging usually isn't necessary and we can proceed straight to treatment — but if you're ever unsure, it's worth getting it checked rather than guessing.
