Objective: To make a cross-cultural adaptation of the MAS for Brazil. Method: The process of cross-cultural adaptation took place in five stages: 1) translation of the original version of the MAS by two independent bilingual translators; 2) synthesis of translations (creation of version 1); 3) back-translation (version 1 in Portuguese was reversed to English by two independent bilingual translators); 4) analysis by the specialists committee (four translators and two physiotherapists); 5) pre-test (application of the instrument in the target population). A Delphi study was also performed and the instrument was submitted to the approval of ten physiotherapists from different states in the country. Results: The consensus about the clarity, semantic equivalence, and technicalscientific relevance of MAS-Brazil was obtained in the second phase of the Delphi study, with agreement between 80 and 100%. In the first phase of the Delphi study, suggestions were made to improve the clarity of the items, which resulted in the Delphi-2 list. Conclusion: The MAS-Brazil was created through an appropriate process of cross-cultural adaptation, ensuring its semantic equivalence and cultural adequacy. It is still necessary to verify the measuring properties of this version for its appropriate use clinically and in research.
