ARTICLE HIGHLIGHTS
Background

Achilles tendinopathy is a major cause of chronic pain and disability. Many studies have been published on a multitude of treatments for Achilles tendinopathy, but prospective series on the outcome are lacking. The Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire was created in 2001 to assess clinical severity for patients with Achilles tendinopathy. It is a self-administered questionnaire evaluating symptoms and their effect on physical activity, and displayed reliability and construct validity.

Research frontiers

The VISA-A has been translated into Swedish, Italian, and German and proved to be able to determine the clinical severity and provide information about the effect of the management of patients with Achilles tendinopathy who speak these languages.

Innovations and breakthroughs

This work translated the VISA-A questionnaire into the Dutch language (VISA-A-NL), assessed its validity and reliability, and provided a valid questionnaire for the Dutch population. The questionnaire seems to be designed only for athletes as 40% of the points account for activity. As approximately 30% of patients with complaints of Achilles tendinopathy have a sedentary lifestyle, applicability to non-athletes was also evaluated.

Applications

Psychometric properties of the VISA-A-NL, without questions 7 and 8, are satisfactory for both athletes and non-athletes. It is therefore proposed that the modified VISA-A-NL questionnaire is considered for a mixed population of patients with Achilles tendinopathy.
