Brief Summary

Fear of re-injury and deficiencies in ankle joint function are common conditions amongst high performance (elite) athletes with chronic ankle instability (CAI), who participate in indoor sports. This fear of re-injury associates with the high recurrence rate of lateral ankle sprains, which is a primary characteristic feature of CAI. The Spraino® shoe patch is a new Danish invention, which is designed to reduce the risk of sustaining lateral ankle sprains in this population. This cohort study will investigate self-reported fear of re-injury and objectively measured ankle joint function in elite indoor sports athletes with CAI, both before and after a 10-week period during which they will use Spraino® during all training sessions and games.

Outcome Measures

Primary Outcomes (1)

  • Fear of re-injury (Continuous)

    Fear of re-injury will be measured using a Numeric Rating Scale (NRS) from 0 to 100 with 10-point increments (e.g. by asking the participants: "How fearful are you of re-injuring your ankle?"), with lower scores indicating more fear of re-injury.

    10 weeks

Secondary Outcomes (7)

  • Y-balance test (Continuous)

    10 weeks

  • The side-hop test (fastest time). (Continuous)

    10 weeks

  • The Foot and Ankle Ability Measure (FAAM) sports scale

    10 weeks

  • Tampa Scale of Kinesiophobia-11 (TSK-11)

  • Fear-Avoidance Beliefs Questionnaire (FABQ)

Study Arms (1)

Spraino intervention group

EXPERIMENTAL

Participants will use Spraino® as a measure to prevent future lateral ankle sprains during all training sessions and games.

Device: Spraino

Interventions

SprainoDEVICE

Spraino® is an adhesive polytetrafluoroethylene (PTFE or "Teflon") patch developed with the purpose of minimizing lateral shoe-surface friction whenever initial contact is carried out in an inverted position of the ankle joint. Each Spraino® PTFE patch has a minimum durability of 20 hours use and will be provided by the study sponsor, Spraino® ApS. The participants will receive four pairs of Spraino® upon their enrollment to the study.
