Cross-cultural adaptation and validation of the Spanish version of the Cumberland Ankle Instability Tool (CAIT): an instrument to assess unilateral chronic ankle instability.

摘要: The Cumberland Ankle Instability Tool (CAIT) is a valid instrument to determine the presence of chronic ankle instability (CAI) and assess its severity. Self-report test very useful for researchers clinical practice, CAI widespread tool. Nevertheless, there lack measurement instruments validated into Spanish, which represents major difficulty research dealing with Spanish-speaking population. questionnaire was cross-culturally adapted Spanish. psychometric properties tested in Spanish version CAIT were measured internal consistency, test–retest reliability, construct validity, criterion responsiveness 108 participants who recruited from several fitness centers. had high consistency (Cronbach's α = 0.766) reliability (intraclass correlation coefficient 0.979, 95 % confidence interval (CI) 0.958–0.990).
