Cross-cultural adaptation of the Victorian institute of sports assessment - Hamstrings (VISA-H) questionnaire for Spanish speaking athletes with proximal hamstring tendinopathy.

Abstract

OBJECTIVE\nTo cross-culturally adapt and validate the Victorian Institute of Sports Assessment - Hamstrings (VISA-H) scale into Spanish.\n\n\nDESIGN\nClinical measurement study (psychometric analysis).\n\n\nSETTING\nSports clubs and physiotherapy clinics.\n\n\nPARTICIPANTS\nThe Spanish version of the VISA-H (VISA-H-Sp) scale was administered to 101 subjects: 50 healthy runners and 51 patients with a clinical diagnosis of PHT.\n\n\nMAIN MEASURES\nThe Victorian Institute of Sports Assessment - Hamstrings.\n\n\nRESULTS\nCronbach s alpha for the VISA-H-Sp was >0.8. The ICC 2,1 was 0.993 (95%CI 0.991-0.995). In the exploratory factor analysis, a one-factor solution explained 72.1% of the total variance. Athletes with PHT scored significantly lower in the VISA-H-Sp than healthy subjects (P\xa0<\xa00.001). The VISA-H-Sp score results in the PHT group showed significant correlations with SF-36 physical components (Spearman r >0.6; P\xa0< 0.001), and low or non-significant association with psychological dimensions. The standard error of measurement was 1.45 whereas the minimal detectable change was 4.02 points. The responsiveness indicators included an effect size of 2.75, and a standardised response mean of 3.1\xa0at discharge.\n\n\nCONCLUSION\nThe VISA-H-Sp shows adequate psychometric properties for assessing the severity of symptoms in Spanish-speaking athletes who suffer from PHT.
