Rolled (Sprained) Ankle: Symptoms, Causes & PT Treatment
Updated October 20261 minute read
A rolled ankle is a sprain — a stretch or tear of the ligaments, usually on the outer side, when the foot turns inward. It causes pain, swelling, and bruising. Most sprains heal well, and the best evidence supports early controlled movement plus balance and strengthening rehab rather than prolonged rest. Proper rehab matters because poorly rehabbed sprains often lead to repeat sprains. Inability to bear weight with bony tenderness needs an X-ray to rule out a fracture.
What is an ankle sprain?
An ankle sprain is ligament injury from the joint moving beyond its normal range, most often an inversion (inward roll) injuring the outer ligaments.
Symptoms
Common features are outer-ankle pain, swelling, bruising, tenderness, and difficulty walking. Severity ranges from mild stretching to a more complete tear with significant swelling.
What causes it / risk factors
Stepping on uneven ground, sports with cutting and jumping, prior sprains, and reduced balance all raise risk.
How it's diagnosed
A clinician examines the ligaments and uses specific criteria to decide whether an X-ray is needed to rule out a fracture (for example, inability to bear weight plus bony tenderness).
Physical therapy treatment
What a PT does. Your therapist controls early swelling and pain, restores motion, then rebuilds strength and — crucially — balance to prevent re-injury. Exercises & progression (overview). Early controlled movement, strengthening, and balance/proprioception training, progressing to agility and return to sport. Balance training notably reduces repeat sprains. Recovery timeline. Mild sprains often improve within a few weeks; full rehab to prevent recurrence may take longer.
Treatment options compared
Early active rehab is first-line. Bracing or taping can support early return. Surgery is rarely needed for typical sprains.
Red flags
Seek prompt care for inability to bear weight with bony tenderness (possible fracture), severe deformity, numbness, or a cold/pale foot.
