Cross-cultural adaptation to Brazilian Portuguese of the Waterloo Footedness Questionnaire-Revised: WFQ-R-Brazil

<div><p>ABSTRACT Post-stroke hemiparesis causes compensated postures, which can modify the footedness established before the impairment. Recently, a paresis severity-modulated dominance hypothesis stated that measures to detect footedness become crucial to float new ideas for neurorehabilitation strategies. The Waterloo Footedness Questionnaire-Revised (WFQ-R) represents the most acceptable measure but it had not yet been cross-culturally adapted for Portuguese spoken in Brazil. Our aim was to cross-culturally adapt the WFQ-R to Brazilian Portuguese, verifying its reliability. We completed the essential steps to cross-culturally adapt one version, tested in 12 patients with post-stroke hemiparesis and 12 able-bodied individuals, sampled by convenience, to verify reliability. Measurements were taken by two independent raters during the test and by one of them at the one-week retest. No great semantic, linguistic or cultural differences were found, and acceptable reliability was recorded. The WFQ-R-Brazil is reliable and ready for use in the Brazilian able-bodied and post-stroke hemiparesis population.</p></div>
