Outcomes
Ankle Disability, pain
Participants completed, after baseline, online questionnaires at 4, 8, 12, 16, 21, 26, 31, 35, 39, 43, 47, and 52 weeks’ follow-up. The baseline questionnaire included questions on demographics, educational level (‘low’, ‘middle’, or ‘high’), comorbidities, paid job (‘yes, <16 hours’, ‘yes, >16 hours’, or ‘no’), sports participation (‘yes’ or ‘no’), minutes of sport participation per week, previous LASs, Ankle Function Score (AFS) (0–100) and Foot and Ankle Disability Index (FADI) (0–100),All follow-up questionnaires collected information about the previous month and included the occurrence of a recurrent LAS of the index LAS, subjective recovery (measured on a 7-point Likert scale ranging from 1 ‘completely recovered’ to 7 ‘worse than ever’; patients are deemed to be recovered if they rate themselves as ‘completely recovered’ [ = 1] or ‘strongly recovered’ [ = 2] on the Likert scale, whereas those who rate themselves as ‘3, slightly recovered’ to ‘7, worse than ever’ are deemed to be not recovered), AFS (0–100),The primary outcome was the difference in self-reported recurrent LAS between the intervention and control group during 1-year follow-up. A recurrent LAS was defined as a re-sprain of the index LAS.Secondary outcomes were differences in ankle function, pain at rest and during activity, subjective recovery, and sport participation (type and level) at 12, 26, and 52 weeks.
