Το ερωτηματολόγιο VISA-A questionnaire κατασκευάστηκε στα αγγλικά το 2001 για το Victorian Institute of Sport Tendon Study Group. Μεταφράστηκε σε άλλες γλώσσες. Αποτελείται από 8 ερωτήσεις, οι οποίες αξιολογούν τον πόνο, τη λειτουργικότητα, την καθημερινή δραστηριότητα και την αθλητική δραστηριότητα του ασθενή με πρόβλημα στον Αχίλλειο τένοντα. Δεν αποτελεί μέσο διάγνωσης όπως σημείωσαν οι ερευνητές, αλλά είναι ένα έγκυρο και αξιόπιστο μέσο αξιολόγησης της σοβαρότητας της τενοντοπάθειας του Αχίλλειου τένοντα.

Methods For the cross-cultural adaptation, the back-translation procedure was utilised, comprising forward and backward translations by 4 bi-lingual translators. Three groups of 61 healthy people (mean age: 25.8, SD: 5.2), 15 athletes (mean aged: 23.4, SD: 5.1) and 14 patients with Achilles tendinopathy (Mean aged: 30.6, SD: 7.7), were included for the validity study. Subjects were requested to complete the VISA-A along with Percy/Conochie and Stanish/Curwin Scales via interviews. For reliability, all participants completed two more VISA-A one hour and one week after the 1st assessment.
Results Content validity of the Greek versions of the VISA-A questionnaire was achieved as all participants found the questionnaires appropriate and comprehensible. Concurrent validity of VISA-A with Percy and Conochie scale yielded moderate correlation (Spearman r = 0,632, p = 0,252) whereas with Stanish and Curwin scale the correlation was strong and significant (Spearman r =- 0,74, p = 0,002). Differences between healthy and patients were also significant. Test–retest of VISA-A was excellent with very small error between measurements for all participants (ICC>.89). Internal consistency was also very high (Cronbach a = 0.94).
