Accepts healthy volunteers: yes
Observational model: COHORT
Time perspective: CROSS_SECTIONAL
Sampling method: PROBABILITY_SAMPLE
Study population: Basketball athletes with a history of ankle sprain, at least one year of basketball experience, and who participate in basketball training at least once per week.

Brief summary: The aim of our study is to evaluate the applicability, validity, and reliability of the Cumberland Ankle Instability Tool (CAIT) in basketball athletes. Given that a significant proportion of injuries in basketball occur in the ankle, our study holds importance for instability assessments conducted in this population. If the Cumberland Ankle Instability Tool is found to be applicable in basketball athletes, it may be utilized in future research.

Detailed description: The aim of our study is to evaluate the applicability, validity, and reliability of the Cumberland Ankle Instability Tool (CAIT) in basketball athletes. Since most injuries in basketball occur in the ankle, our study is significant for assessing instability in this population. If the Cumberland Ankle Instability Tool is found to be applicable in basketball athletes, it may be utilized in future research.

Hypotheses:

H₀ (Null Hypothesis): The Cumberland Ankle Instability Tool is not applicable, valid, or reliable in basketball athletes.

H₁ (Alternative Hypothesis): The Cumberland Ankle Instability Tool is applicable, valid, and reliable in basketball athletes.

The demographic information of the athletes, including height, age, weight, and years of sports experience, will be recorded. The Cumberland Ankle Instability Tool (CAIT) will be created using Google Forms and distributed to the athletes online.

To assess the reliability of the questionnaire, it will be administered twice to the athletes within a 3 to 7-day interval. The following reliability parameters will be calculated:

Internal consistency, Test-retest reliability, Standard error of measurement (SEM), Minimal detectable change (MDC). For validity assessment, the relationship between the Cumberland Ankle Instability Tool (CAIT) and the Foot and Ankle Ability Measure (FAAM) as well as the Identification of Functional Ankle Instability (IdFAI) will be analyzed.

Eligibility criteria: Inclusion Criteria:
