Description of intervention(s) / exposure
A Delphi approach will be used to establish consensus of opinion from a panel of experts on RTS criteria and the definition of successful RTS after an acute lateral ankle sprain injury. There are three planned Delphi rounds, that will be 1-2 months apart. The process for each Delphi round will involve: data collection via an online survey (using the SurveyMonkey platform), analysis of responses, and provision of feedback to panelists. The goal of the Delphi process is to achieve consensus, a priori defined as >70% agreement between panelists.

For each Delphi round, expert panelists will be sent an email invitation with a link to an anonymous online survey. The first round of the Delphi survey will include a combination of structured and open response questions informed by a review of the literature. The second and third Delphi rounds will predominantly use structured questions with Likert rating responses (“Yes”, “No” or “Unsure/I do not know”). These rounds aim to quantify findings from the previous round and form a consensus among participants.

Content analysis will be used to identify themes from open response questions. Responses will initially be read for familiarisation and then re-read for identification of themes. Once themes are identified, data will be categorised. For trustworthiness and to decrease risk of bias, this process will be undertaken independently by two researchers. Analyses will be discussed between the two researchers to achieve agreement, and any items for which agreement is not achieved will be discussed with a third party. This will culminate in a list of RTS criteria from the open responses that will be developed into structured questions for the subsequent Delphi round.

Structured questions that reach consensus (>70% of panelists agreed on the inclusion or exclusion of the RTS criteria for use in sportspersons after a lateral ankle sprain) will be removed from the survey for the following round. A participant’s opinion to include a RTS criteria is defined as selection of the “Yes” Likert option, and an opinion to exclude a RTS criteria is defined a selection of the “No” option.

Between each round, feedback on the previous round will be provided to participants via email. Data from structured questions will be presented back to participants as the percentage of panelists who selected each answer category. Data from open response questions will be summarised as new RTS criteria/themes that have come out of participant responses. A thematic summary of explanation of responses will be included after each structured question that did not reach consensus in the previous round.

Outcomes
Primary outcome [1] 307752 0
Panelists will be asked to indicate if they feel the assessment of a certain outcome should be a criterion to support the return to sport decision after an acute lateral ankle sprain. Possible answers include 'yes', 'no' or 'unsure'. Outcome that will be asked about include: swelling, pain, range of motion, arthrokinematics, ligamentous laxity, muscle function (strength, endurance, power), proprioception, balance, kinematics, physical and sport specific activities, fitness, and patient-reported outcomes.

Achievement of agreement between panelists will be calculated for each response item and is defined as >70%,
Timepoint [1] 307752 0
After three Delphi survey rounds separated by approximately 4-6 weeks (i.e. 0 weeks, 6 weeks and 12 weeks).
Secondary outcome [1] 352785 0
Summary data of demographics of survey participants including age, sex, profession, years worked, sport employed with, and experience managing return to sport after lateral ankle sprain injuries will be assessed using a purpose-designed online survey.
Timepoint [1] 352785 0
After completion of the third Delphi round (~12 weeks).

Eligibility
Key inclusion criteria
Eligibility criteria for participants (expert panelists) are: i) health professional (e.g. physiotherapist, athletic trainer/therapist, sports medicine physician); ii) currently working with athletes competing in nationally selected representative teams or teams in Tier/Division 1 national competitions (e.g. English Premier League, NCAA Division 1, Suncorp Super Netball); iii) currently working in field or court sports in which the primary gross motor skills are running and jumping/landing or changing direction and there is a high prevalence of lateral ankle sprain injuries; iv) involved in making RTS decisions for individuals with an acute lateral ankle sprain injury; v) proficiency in the English language. The sports to be targeted for this study include: basketball, volleyball, netball, handball, korfball, soccer, rugby, American/Canadian football, Australian rules football, Gaelic football, lacrosse, field hockey, hurling, camogie, tennis, badminton and squash.
