Chronic ankle instability is a combination of mechanical (excessive range of motion) and functional (subjective feelings of instability) instability of the ankle. People with a history of ankle sprain are at risk for chronic ankle instability.
Conditions
Interventions
Measurements will be conducted with and without ankle brace. The ankle brace used in this study will be the Push Med Ankle Brace (Nea International, Maastricht, the Netherlands). The order of measurem

Eligibility
Inclusion criteria
Inclusion criteria: In order to be eligible to participate in this study, a subject must meet all of the following criteria, which is a copy of the advised selection criteria for study participants with CAI, provided by the International Ankle Consortium: 1. A history of at least 1 significant ankle sprain - Definition ankle sprain: “An acute traumatic injury to the lateral ligament complex of the ankle joint as a result of excessive inversion of the rear foot or a combined plantar flexion and adduction of the foot.30” - The initial sprain must have occurred at least 12 months prior to study enrollment - Was associated with inflammatory symptoms (pain, swelling etc.) - Created at least 1 interrupted day of desired physical activity - The most recent injury must have occurred more than 3 months prior to study enrollment 2. A history of the previously injured ankle joint “giving way” and/or recurrent sprain and/or “feelings of instability A. Definition giving way: “The regular occurrence of uncontrolled and unpredictable episodes of excessive inversion of the rear foot (usually experienced during initial contact during walking or running), which do not result in an acute lateral ankle sprain.” - Specifically, participants should report at least 2 episodes of giving way in the 6 months prior to the study enrollment. B. Definition recurrent sprain: “two or more sprains to the same ankle” C. Definition feeling of ankle joint instability: “The situation whereby during activities of daily living and sporting activities the participant feels that the ankle joint is unstable and is usually associated with the fear of sustaining an acute ligament sprain” - Specifically, self-reported ankle instability should be confirmed with the Cumberland Ankle Instability Tool (CAIT) with a score under 24.
Exclusion criteria
Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study (a copy of the advised selection criteria for study participants with CAI, provided by the International Ankle Consortium): • A history of previous surgeries to the musculoskeletal structures (i.e., bones, joint structures, nerves) in either limb of the lower extremity • A history of a fracture in either limb of the lower extremity requiring realignment • Acute injury to musculoskeletal structures of other joints of the lower extremity in the previous 3 months, which impacted joint integrity and function (i.e., sprains, fractures) resulting in at least 1 interrupted day of desired physical activity.

| Measure | Time frame |
|---|---|
| The main study parameters of this study will be the difference of joint position sense (JPS) and dynamic postural control between the measurement with and without ankle brace. JPS will be measured using the Angle Reproduction Test. Dynamic postural control will be measured using the Y Balance Test (Functional Movement Systems, Danvile, USA). | — |
