Ankle Sprain Physiotherapy in Perth

The Ottawa Ankle Rules are a validated clinical decision tool for determining whether an X-ray is needed after ankle injury. X-ray is indicated if there is bone tenderness at the posterior edge or tip of either malleolus (the bony prominences on each side of the ankle), or inability to bear weight for 4 steps both immediately after the injury and in the clinic. If none of these are present, the likelihood of a fracture is very low. Your physiotherapist applies these rules at your initial assessment. If an X-ray is indicated, you will be directed to an emergency department or imaging facility. Most ankle injuries presenting to physiotherapy are sprains rather than fractures, but this is always assessed carefully.

Recovery time depends on the sprain grade. Grade 1 (minor stretching): 1-2 weeks. Grade 2 (partial tear): 3-6 weeks. Grade 3 (complete rupture): 6-12 weeks. These timelines assume appropriate rehabilitation -- simply resting until pain resolves leaves the ankle with persistent proprioceptive deficits and strength loss that significantly increase re-injury risk. The most important predictor of long-term outcome is whether comprehensive rehabilitation addressing strength, proprioception, and functional movement is completed. Athletes managed with structured rehabilitation return to sport faster and with lower re-injury rates than those managed with rest alone.

Recurrent ankle sprains are a common and preventable problem. After an initial lateral ankle sprain, the ligaments are stretched and the proprioceptive receptors within them are damaged. Without rehabilitation, strength and proprioception deficits persist -- leaving the ankle vulnerable to re-sprain under any unexpected loading condition. Studies show that up to 70% of people who sprain their ankle never fully rehabilitate it, and recurrence rates in this group are high. A structured rehabilitation program addressing strength, proprioception, and functional stability significantly reduces re-injury risk. Ankle bracing can also provide useful external support during high-risk activities while rehabilitation is in progress.

In the acute phase (first 24-72 hours), ice (applied with a cloth between the ice and skin for 15-20 minutes at a time, repeated every 2-3 hours) helps manage swelling and pain. Compression bandaging and elevation of the ankle above heart level during rest also reduce swelling in this phase. Heat is not appropriate in the acute phase as it increases blood flow and can worsen swelling. After the acute phase has resolved (usually after 48-72 hours), heat may help reduce muscle stiffness. It is important to note that neither ice nor heat drives recovery -- they manage symptoms. The treatments that drive recovery are movement, loading, and progressive rehabilitation.
