Ankle sprains are the most common sports injury worldwide — yet they are routinely undertreated. "Walk it off" and "just rest it" are common refrains that lead to chronic ankle instability in up to 40% of people. A proper physiotherapy rehabilitation program is what prevents a simple sprain from becoming a lifelong problem.
What Happens in an Ankle Sprain?
Most ankle sprains are lateral (outer ankle) sprains caused by the foot rolling inward. The anterior talofibular ligament (ATFL) is the most commonly injured structure, followed by the calcaneofibular ligament (CFL). The ligament fibres stretch or tear, causing pain, swelling, and bruising.
Beyond the ligament injury, ankle sprains cause significant damage to the proprioceptive nerve endings within the ligament tissue. These nerve endings sense joint position and help stabilise the ankle subconsciously. When they are damaged, the ankle loses its ability to self-correct — leading to chronic instability and recurrent sprains if not specifically rehabilitated.
Grades of Ankle Sprain
- Grade 1: Mild stretch, no significant tear, minimal swelling, full weight-bearing. Recovery: 1–3 weeks.
- Grade 2: Partial tear, moderate swelling and bruising, some instability. Recovery: 3–6 weeks.
- Grade 3: Complete ligament rupture, significant swelling and bruising, mechanical instability. Recovery: 6–12+ weeks.
Physiotherapy Treatment
- Acute phase (Days 1–5): PEACE & LOVE protocol, compression, elevation, pain-free range of motion exercises, progressive weight-bearing as tolerated
- Rehabilitation phase (Week 1–4): Strengthening of the peroneal muscles (the primary ankle stabilisers), single-leg balance and proprioception training, gait retraining
- Advanced phase (Week 3–8): Hopping, jumping, change of direction, sport-specific drills, agility training
- Return to sport: Ability to hop on the injured ankle equal to uninjured side, single-leg squat symmetry, passing functional tests specific to the sport
Chronic Ankle Instability
If you have had multiple ankle sprains or your ankle feels unstable even when walking on uneven ground, you likely have chronic ankle instability. This is extremely responsive to physiotherapy — a focused 6–8 week program of peroneal strengthening and proprioception training resolves instability in the majority of cases without surgery.
Frequently Asked Questions
Should I wrap my ankle after a sprain?
Yes — compression with a bandage or brace in the first 48–72 hours reduces swelling. Elevation and ice also help. You should be able to walk on it within a day or two for Grade 1 sprains. Crutches may be needed for Grade 2–3 sprains if walking is too painful.
My ankle sprain happened months ago but it's still weak. Is it too late for physio?
No. Many people present months or years after an ankle sprain with chronic instability — persistent weakness, frequent re-spraining, and reduced confidence on uneven ground. Physiotherapy is very effective for this presentation at any stage.
Will I need a boot or brace?
For Grade 1–2 sprains, a functional ankle brace (not a rigid boot) is now preferred over immobilisation. It allows movement and normal tissue healing while protecting the ligaments. Grade 3 tears may benefit from a short period in a boot initially.
Can I run with an ankle sprain?
Not initially. Running requires full weight-bearing strength and proprioception through the ankle. A graduated return-to-running program starting with walking, then jogging, then faster running is appropriate once you can hop on the injured ankle without pain.
