Objectives: In this study, the objective was to evaluate the validity and reliability of the Turkish version of the Victorian Institute of Sports Assessment – Achilles (VISA-A) questionnaire for patients with Achilles tendnopathy.
Design: Fifty-five patients with a diagnosis of Achilles tendinopathy and fifty five healthy subjects were included in the study. VISA-A questionnaire were translated and culturally adapted into Turkish language. The final Turkish version, the VISA-A Turkish version (VISA-A-Tr) was tested for reliability on healthy individuals and patients. Tests for internal consistency, validity and structure were performed on 55 patients.
Results: The VISA-A-Tr showed good test-retest reliability (Pearson's r = 0.99, p<0.001). There was no statistically significant difference between the scores of the first, second and third tests in both healthy individuals and patients.
The patients with Achilles tendinopathy had a significantly lower score (p < 0.001) compared with the healthy individuals. The mean VISA-A-Tr score was 52.9±13.6 (range 24–72) for the patients and 97.1±1.5 (range 95–100) for the healthy individuals.
The internal consistency of the scale (Cronbach’s alpha coefficient) was 0.66. The VISA-A-Tr score correlated significantly with another tendon grading system (Spearman's r = -0.86; p < 0.001). There was a significant correlation with the physical domain of the quality of life assessment tool (WHOQOL-BREF) (Spearman's r= +0.37; p < 0.01).
Conclusion: The Turkish version of the VISA-A is a valid and reliable tool for evaluating the severity of the Achilles tendinopathy.
