REHAB & INJURY PREVENTION

Returning to Training After an Ankle Sprain

Grades, timeframes and the functional return criteria that matter more than the calendar — plus the staged path back to jumping.

The calendar is a poor guide for returning from an ankle sprain. Grade tells you the starting point; function tells you when you are ready. Returning too early raises re-sprain risk roughly five-fold.

Timeframes by grade

Lateral ankle sprains fall into three broad grades:

Grade I (mild stretch): 1–2 weeks to light training.
Grade II (partial tear): 4–6 weeks of gradual return.
Grade III (complete tear): 3–6 months, with medical assessment first.

Functional return criteria

Do not return until you can pass all of these:

Single-leg stand over 30s eyes open, then progress to 30s eyes closed.
Over 15 pain-free single-leg calf raises.
10 single-leg small hops, stable and without fear.
Y-Balance test with left/right difference under 4 cm.

The staged return path

Work through each stage only when the previous one is pain-free: pain-free range of motion → band resistance → proprioception → bodyweight jumps → plyometrics. Skipping stages is how sprains become chronic.

Key takeaways

Grade sets the timeline; function decides readiness.
Pass balance, strength and hop criteria before jumping again.
Early return multiplies re-sprain risk by ~5x.
