Turkish Language and Cross-cultural Adaptation of the Cumberland Ankle Instability Tool

Cumberland Ankle Instability Tool (CAIT) is a valid patient-reported outcome measure (PROM) to determine the presence of ankle instability (AI) and assess its severity. The aim of current study is to adapt the CAIT into the Turkish language, test its psychometric properties and determine cut-off score in the Turkish population with AI compare to healthy counterparts. In order to evaluate the Turkish version of CAIT (CAIT-TR), data will obtaine from 200-250 participants with and without AI. Test-retest reliability, internal consistency, cut-off score, and ceiling and floor effects will evaluate.
