Returning to running after an ankle sprain

Ankle sprains have a high recurrence rate, and the reason is rarely that the ligament failed to heal. It is that the ankle’s sense of its own position — proprioception — was never retrained, so the joint keeps getting caught in the same vulnerable position.

The part most people skip

Ligaments carry nerve endings that tell your brain where the joint is. Damage them and that signal degrades, so your foot lands slightly less accurately on uneven ground. Strength work alone does not restore it. Balance work does.

Standing on one leg is the entry point: first with eyes open, then eyes closed, then on a softer surface, then while doing something else with your hands. It looks trivially easy and is not.

Before you run again

• You can hop on the injured leg, repeatedly, without pain
• You can balance on it for 30 seconds with your eyes closed
• Calf strength is comparable side to side — count single-leg heel raises
• You can change direction at speed without hesitating

If any of those are missing, running is not the next step; it is the step after.

Coming back sensibly

Start with a walk-run pattern on flat, predictable ground. Add distance before you add pace, and add pace before you add trail or camber. Expect this to take a few weeks rather than a few days.

Swelling that returns after every run means you are progressing faster than the ankle is adapting.
