PURPOSE
The Victorian Institute of Sport Assessment - Achilles tendinopathy questionnaire (VISA-A) evaluates the clinical severity of Achilles tendinopathy. The aim of this study was to translate the VISA-A into French and to study the reliability and validity of this French version, the VISA-AF.

METHOD
The VISA-A was translated into French to produce the VISA-AF using a validated methodology in six steps. Thereafter, several psychometric properties of this French version such as test-retest reliability, internal consistency, construct validity and floor and ceiling effects were evaluated. Therefore, we recruited 116 subjects, distributed into 3 groups: pathological patients (n?=?31), at-risk athletes (n?=?63) and healthy people (n?=?22).

RESULTS
The final version of the VISA-AF was approved by an expert committee. On a scale ranging from 0 to 100, the average scores of the VISA-AF obtained were 59 (±?18) for the pathological group, 99 (±?1) for the healthy group and 94 (±?7) for the at-risk group. The VISA-AF shows excellent reliability, low correlations with the discriminant subscales of the SF-36 and moderate correlations with the convergent subscales of the SF-36.

CONCLUSIONS
The French version of the VISA-A is equivalent to its original version and is a reliable and valid questionnaire for French-speaking patients with Achilles tendinopathy. Implication for Rehabilitation The VISA-AF questionnaire is a reliable translation of the original VISA-A, from English into French, which is one of the most widespread languages in the world. The VISA-AF questionnaire is now a valid instrument that can be used by clinicians and researchers to assess the severity of pain and disability of French-speaking subjects with Achilles tendinopathy. The VISA-AF is a questionnaire to assess the severity of Achilles tendinopathy symptoms but is not a diagnostic tool.
