Tradução e Adaptação Cultural do Questionário PRTEE (patient-rated tennis elbow evaluation) para a Língua Portuguesa

Abstract

Introduction: Frequently found in clinical rehabilitation, tennis elbow may induce pain and functional decline. Its evaluation is considered crucial; however, some evaluations lack more individuals’ functional information. In Brazil, this disorder doesn’t have any specific evaluation tools. The development of the ‘Patient-rated Tennis Elbow Evaluation’ (PRTEE) questionnaire, in Canada, has enabled tennis elbow measurement through a systematic approach of translation and cultural adaptation of the survey. Purpose: To translate the English version of the Patient-rated Tennis Elbow Evaluation questionnaire to Portuguese; check the level of understanding among health professionals and laymen; identify suggestions regarding its structure; and develop a new version, culturally adapted to the Brazilian population. Methods: Two translations of the original English version to Portuguese were prepared; they were then translated back in two new English versions. The two new English translations were compared to the original English version; they were analyzed and, in the presence of differences, modified. A Brazilian version of the Patient-rated Tennis Elbow Evaluation was obtained and assessed concerningits contents and cultural equivalence. In order to verify the level of understanding, the questionnaire was applied to health professionals (48) and laymen (52). In the process of cultural equivalence of the instrument, the questions indexed as not-understood were reformulated. Results: In the first application, three items of the questionnaire reached a percentage greater than 15% of not-understood. After being reformulated and reapplied, these items showed high percentage of understanding. Conclusion: A culturally adapted version of the Patient-rated Tennis Elbow Evaluation (PRTEE) was developed to Brazilian health professionals and laymen
