504 patients with a grade I or II ankle sprain seeking care in an acute care setting were randomized to usual care, including protection, rest, ice, compression, and elevation (PRICE) with or without participation in a standardized physiotherapy program. The purpose of this study was to evaluate if patients who participated in the physiotherapy program demonstrated significantly better function on the Foot and Ankle Outcome Score (FAOS) over a 6-month follow-up. No significant differences were observed between groups in the rate of patients demonstrating excellent recovery (FAOS score >450/500) at 1, 3, or 6 months, or in mean FAOS total or specific domain scores at 1, 3, or 6 months.
