Abstract
PURPOSE: Achilles tendinopathy is a prevalent overuse injury among athletes and in those with a sedentary lifestyle. Current evidence indicates that the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire is a valid, reliable and disease-specific outcome measure for assessing the clinical symptoms in patients with Achilles tendinopathy. The objective of this study was to translate and cross-culturally adapt the VISA-A questionnaire into Persian (VISA-A-P) and evaluating its psychometric properties. MATERIALS AND METHODS: Cultural adaptation of VISA-A-P was conducted according to Beaton's guideline. The final version of VISA-A-P was handed to 61 patients for analysis of psychometric properties. Test-retest reliability, internal consistency, concurrent validity, item-total correlation, and floor/ceiling effect were evaluated in patients with Achilles tendinopathy. To assess test-retest reliability, 35 patients refilled the VISA-A-P twice within 5-7 days. Known-group validity was evaluated using 50 healthy individuals. RESULTS: VISA-A-P showed excellent test-retest reliability (ICC = 0.90), excellent internal consistency (Cronbach's alpha = 0.95), strong correlation with FAAM, and moderate to strong correlation with FAOS questionnaires. There was a significant difference between the average score of patients (34.55 ± 18.24) and the healthy group (73.1 ± 20.10). VISA-A-P showed neither ceiling nor floor effect. CONCLUSIONS: The VISA-A-P is a reliable and valid instrument for measuring the symptoms in Persian speaking populations with Achilles tendinopathy.Implications for rehabilitationAchilles tendinopathy is a debilitating overuse injury that insidiously affects tendoAchilles.VISA-A-P revealed acceptable validity and reliability and it could be used by Persian speaking clinicians and researchers to assess pain and function in people with Achilles tendinopathy.
