BACKGROUND: Ankle sprains are highly prevalent with high risk of recurrence. Consequently, there are a significant number of research reports examining strategies for treating and preventing acute and recurrent sprains (otherwise known as chronic ankle instability (CAI)), with a coinciding proliferation of review articles summarising these reports. OBJECTIVE: To provide a systematic overview of the systematic reviews evaluating treatment strategies for acute ankle sprain and CAI. DESIGN: Overview of intervention systematic reviews. PARTICIPANTS: Individuals with acute ankle sprain/CAI.
