Methods: The process was conducted in five stages: translation of the questionnaire into Brazilian Portuguese; development of a first consensual version in Brazilian Portuguese; appraisal of the translation by an expert committee; back-translation; and semantics assessment of the instrument. For semantic evaluation, the translated and adapted Brazilian Portuguese versions were applied to a convenience sample of 10 individuals. Results: The translated instrument showed a high degree of comprehension within the target population, as it was observed all questions from Part I and II were score 4 or higher on an Ordinal Scale ranging from 0 to 5. Conclusion: The Brazilian version of Trinity Amputation and Prosthesis Experience Scales-Revised has a satisfactory verbal comprehension and is now ready for assessment of its psychometric properties.
