The Brazilian version of the Victorian Institute of Sport Assessment - Hamstring (VISA-H) Questionnaire: Translation, cross-cultural adaptation and measurement properties.

STUDY DESIGN: Study of diagnostic accuracy/assessment scale. BACKGROUND: Proximal hamstring tendinopathy (PHT) usually causes disability, deep pain in the proximal insertion of the tendon, and limitations in daily life and sports practice. Scales that assess PHT pain and disability may assist practitioners in their clinical decision-making processes. OBJECTIVES: To perform a translation, cross-cultural adaptation and to evaluate the measurement properties of the Victorian Institute of Sport Assessment - Hamstring (VISA-H) questionnaire for the Brazilian population. METHODS: The VISA-H was adapted to Brazilian Portuguese (VISA-H-Br) and applied in 2 occasions with 5-8-day intervals. The following measurement properties were evaluated: internal consistency, test-retest reliability, standard error of the measurement (SEM), smallest detectable change (SDC), structural validity, and construct validity. Ninety (n = 90) participants (40 PHT and 50 asymptomatic participants) were evaluated using the Lower Extremity Functional Scale (LEFS) and VISA-H. PHT was diagnosed via clinical examination. RESULTS: The questionnaire was successfully translated, cross-culturally adapted, and renamed VISA-H-Br. The VISA-H-Br questionnaire demonstrated high internal consistency (Cronbach α = 0.96), excellent test-retest reliability (ICC = 0.90, CI 95% 0.83-0.93), and strong construct validity (rho = 0.692, p < 0.01 compared to LEFS). The SEM was 2.15 points, and the SDC was 5.96 points. No ceiling or floor effects were detected. CONCLUSION: The Brazilian version of the VISA-H was consistent, reliable, and valid. Therefore, it may be used in clinical practice and research to assess the pain and disability of patients with PHT.
