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.Keywords: diagnosis; monitoring; hemiplegia.
RESUMOHemiparesia pós-doença cerebrovascular causa posturas compensadas que podem modificar predominância de uso do pé adotada antes da deficiência. Recentemente, hipótese de predominância modulada pela gravidade da paresia declara que medidas para detectar predominância tornaram-se cruciais para sugerir ideias em busca de estratégias de neurorreabilitação. A Waterloo Footedness Questionnaire-Revised (WFQ-R) representa a medida mais aceita e não foi ainda adaptada transculturalmente para o Português brasileiro. Nosso objetivo foi então adaptar o WFQ-R, verificando sua confiabilidade. Nós completamos os passos essenciais para adaptar uma versão testada em 12 pessoas com hemiparesia e 12 fisicamente aptas amostradas por conveniência para procedimentos de verificação da confiabilidade. Medidas foram tomadas por dois examinadores independentes durante o teste e por um deles no reteste após uma semana. Nenhuma diferença semântica, linguística ou cultural foi encontrada, e confiabilidade aceitável foi registrada. WFQ-R-Brasil é confiável e está pronto para uso na população de brasileiros fisicamente aptos e com hemiparesia.Palavras-chave: diagnóstico; monitoramento; hemiplegia Right or left brain asymmetries have been demonstrated in studies of complex cognitive functions such as musical abilities, language, emotions, and visuospatial tasks 1 . Mutha et al. 2 defended that a hemispheric specialization model, in which unilateral hemispheres become responsible through different motor control mechanisms, decreases the energy expenditure and time for communication between processing units (efficiency), optimizing performance. With this rationale, the asymmetry of performing different tasks by choosing a preferred hand or foot
