Simetria na distribuição do suporte de peso em pé : em busca de parâmetros e tecnologias para aplicações diagnósticas e terapêuticas

Tese (doutorado)—Universidade de Brasília, Faculdade de Ceilândia, Programa de Pós-Graduação em Ciências e Tecnologias em Saúde, 2016.O Acidente Vascular Encefálico (AVE) gera posturas inadequadas tanto para iniciar transferências funcionais como para distribuir eficientemente as sobrecargas articulares entre os segmentos do corpo. A redistribuição mais relatada nessa população na postura em pé é a assimétrica com sobrecarga do membro não-afetado, embora evidências apontem para outras estratégias de distribuição do suporte de peso. Além disso, faz-se necessário o desenvolvimento de instrumentos que permitam tanto a análise dessa redistribuição quanto à indução de simetrias/assimetrias. O objetivo do estudo foi investigar parâmetros que subsidiassem o desenvolvimento de tecnologias para análise de efeitos terapêuticos da indução de simetria na distribuição do suporte de peso em pessoas após o AVE. Na primeira etapa do estudo, foram levantadas pesquisas que investigaram a distribuição do suporte de peso nessa população. Confirmou-se que prevalece a ideia de que essas pessoas possuem assimetria com sobrecarga no hemicorpo não-parético. A heterogeneidade dos estudos e a falta de parâmetros de quais são os limites de simetria apontam para necessidade de estudos padronizados e melhor parametrizados quanto ao comportamento assimétrico para melhor compreensão dessas estratégias. Na segunda etapa, analisou-se a percepção dos terapeutas quanto à viabilidade de tecnologia para indução de simetria. Os entrevistados apontaram que tal dispositivo seria útil na reabilitação dessa população. Na terceira etapa, foi realizada a adaptação transcultural e análise da confiabilidade de um instrumento que identifica a predominância de uso de membros inferiores. A WFQ-Brasil mostrou-se útil na identificação do membro preferencialmente usado para diferentes tipos de tarefas. Na fase seguinte, a Escala de Fugl-Meyer e a WFQ-Brasil foram usadas, objetivando verificar a hipótese de predominância de uso severidade-dependente. Os indivíduos com hemiparesia adotaram o membro não-afetado como preferencialmente usado, confirmando a hipótese de conveniência. No entanto, fracas correlações entre as pontuações obtidas nos dois testes apontam para necessidade de analisar pessoas com diferentes níveis de severidade motora para confirmar tal hipótese. Na última fase, foi desenvolvido um dispositivo que monitora a pressão e emite sinal vibratório para alertar o usuário quando a distribuição do suporte de peso entre os pés encontra-se fora dos limites de simetria, objetivando a indução de simetria nessa distribuição. Os procedimentos adotados nos permitiram concluir que a adoção do conceito de limite de simetria deve ser considerada na busca de parâmetros para aplicações diagnósticas e terapêuticas.Stroke generates postures both to start functional transfers as to efficiently distribute the joint burdens between the body segments. The most reported in this population redistribution in the standing posture is the asymmetric toward to non-affected limb, although evidence point to other distribution strategies of weight-bearing. In addition, it is necessary to develop tools to enable both the analysis of this redistribution and the induction of symmetry / asymmetry. The aim of this study was to investigate parameters that subsidize the development of technologies for analysis of therapeutic effects of symmetry induction in weight-bearing distribution in people after stroke. In the first stage of the study, they were raised studies that investigated the weight-bearing distribution in this population. It was observed that was prevalent that idea affirming that subjects with chronic hemiparesis have asymmetric distribution toward to non-paretic hemibody. However, the heterogeneity among studies and the lack of parameters to define limits of symmetry pointing to necessity of additional studies. In the second step, we analyzed the perception of the therapists on the feasibility of technology for inducing symmetry weight distribution support. Respondents indicated that such a device would be useful in the rehabilitation of this population. In the third step, the cross-cultural adaptation and analysis of the reliability of an instrument that identifies the predominant use of lower limbs was performed. The WFQ-Brazil proved to be useful to identification to preferred foot for different types of tasks. In the next phase, the Fugl-Meyer Scale and WFQ-Brazil were used in order to verify the hypothesis of predominance of severity-dependent. Individuals with hemiparesis adopted the non-affected limb as preferably used, confirming the hypothesis of convenience. However, weak correlations between the scores obtained in the two tests point to the need to examine people with different levels of motor severity to confirm this hypothesis. In the last phase, it developed a device that monitors the pressure and emits vibrating signal to alert the user when the weight distribution is outside the limits of symmetry, aiming symmetry induction this distribution. The procedures adopted in the study allowed us to conclude that the adoption the limits of symmetry concept should be considered in the search parameters for diagnostic and therapeutic applications

Adaptação transcultural para o português brasileiro do Waterloo Footedness Questionnaire-Revised : WFQ-R-Brasil

Hemiparesia 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.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
