ABSTRACT BACKGROUND: The Bournemouth questionnaire is a multidimensional instrument for evaluating health domains among patients with low back pain. OBJECTIVE: The objective of this study was to translate and cross-culturally adapt the Bournemouth questionnaire for individuals with low back pain, to Brazilian Portuguese. DESIGN AND SETTINGS: This was a cross-sectional study conducted at the Federal University of São Carlos. METHODS: The Brazilian version of the Bournemouth questionnaire was developed following the processes of translation, back-translation, committee review and pre-testing. The translation phase involved two independent bilingual translators whose mother language was Brazilian Portuguese. The back-translation phase involved two independent translators whose mother language was English. In order to verify comprehension of the questionnaire, 44 individuals (43.1% men) with low back pain, and with mean age of 45.4 ± 13.8 years, participated in the pre-testing phase. RESULTS: During the translation phase, some terms and expressions were changed to obtain cultural equivalence to the original Bournemouth questionnaire. In the pre-testing phase, each item of the questionnaire showed a comprehension level of over 90%. CONCLUSION: The Bournemouth questionnaire was translated and culturally adapted to the Portuguese language, to be used among individuals with low back pain.

ABSTRACT BACKGROUND: The revised foot function index (FFI-R) is used to evaluate the functionality of patients with conditions that affect the feet. The objective here was to produce the Brazilian Portuguese version of this index. DESIGN AND SETTING: Translation and validation study conducted at the Federal University of São Paulo, Brazil. METHODS: The translation and cultural adaptation process involved translation by two independent translators, analysis by an expert committee, back translation into the original language, analysis by the expert committee again and a pretest. The Portuguese-language version was administered to 35 individuals with plantar fasciitis and metatarsalgia to determine their level of understanding of the assessment tool. RESULTS: Changes were made to the terms and expressions of some original items to achieve cultural equivalence. Terms not understood by more than 10% of the sample were altered based on the suggestions of the patients themselves. CONCLUSION: The translation and cultural adaptation of the FFI-R for the Portuguese language were completed and the Brazilian version was obtained.

RESUMO O objetivo deste estudo foi traduzir o ABILHAND-Kids para o português brasileiro, adaptá-lo culturalmente e verificar sua validade e confiabilidade. O ABILHAND-Kids foi traduzido para o português e a tradução reversa foi feita por dois tradutores independentes em cada fase. Após a aprovação do comitê, a versão pré-teste foi aplicada em 40 voluntários com filhos com paralisia cerebral para verificar a compreensão dos itens. Participaram da análise das propriedades psicométricas 21 voluntários. A reprodutibilidade foi verificada por análise da confiabilidade intra e interavaliador e a validade pela correlação com o Box and Block Test, Purdue Pegboard Test e força de preensão manual. O ABILHAND-Kids demonstrou alta confiabilidade intra-avaliador (ICC=0,91) e interavaliador (ICC=0,97) e alta consistência interna (Alfa de Cronbach: 0,99). O ABILHAND-Kids apresentou correlação significativa com Box and Block Test (realizado pelo membro superior dominante), com o Purdue Pegboard Test and a força de preensão. A versão brasileira do ABILHANDkids é válida e confiável para avaliar a função de membros superiores em crianças com Paralisia Cerebral, com base na percepção de seus pais.

ABSTRACT This study aimed to translate, to adapt cross-culturally and to validate the ABILHAND-Kids for the Brazilian Portuguese. ABILHAND-Kids was translated to Brazilian Portuguese and translated back by two certified translators in each phase. After the expert committee approval, the pre-test version was applied in 40 parents of children with cerebral palsy in order to verify item comprehension. Twenty-one volunteers were enrolled in the psychometric properties analysis. Reproducibility was verified by interrater and intrarater reliability and the validity was tested by investigating Box and Block Test, Purdue Pegboard Test and grip strength correlations. ABILHAND-Kids showed strong intrarater (ICC=0.91) and interrater (ICC=0.97) reliability and high internal consistency (Cronbach’s alfa: 0.99). ABILHAND-Kids showed significant correlations with Box and Block Test (performed by dominant upper extremity), Purdue Pegboard Test and grip strength. The Brazilian Portuguese version of ABILHAND-Kids is a reliable tool to measure upper extremities function of children with cerebral palsy, based on the perception of their parents.

Resumo Introdução: A fasciíte plantar (FP) caracteriza-se por uma degeneração não inflamatória e dor na parte inferior do calcanhar, sendo uma das queixas mais comuns na região do pé. As compensações e as adaptações para diminuir o desconforto da doença é um achado clínico e atua como um fator que pode contribuir para o comprometimento no equilíbrio e no desempenho funcional. Objetivo: comparar os equilíbrios estático, dinâmico e o desempenho funcional entre indivíduos com e sem a FP. Métodos: participaram da pesquisa 124 voluntários distribuídos em dois grupos: grupo fasciíte plantar bilateral (GFP; n = 62) e grupo controle (GC; n = 62) de ambos os sexos, na faixa etária de 20 a 60 anos. Os desfechos analisados foram o equilíbrio estático, equilíbrio dinâmico por meio dos testes funcionais e o desempenho funcional por um questionário. Os resultados foram analisados utilizando o teste t de Student de amostras independentes para comparar as variáveis entre os grupos. O erro alfa considerado foi p < 0,05. Resultados: Indivíduos com FP apresentaram maior comprometimento durante o teste de equilíbrio dinâmico total (p < 0,001), exceto no movimento póstero-medial esquerdo (p = 0,19). O GC apresentou melhor desempenho funcional (p < 0,001) e não houve diferença entre os grupos para a variável equilíbrio estático nas superfícies estável (p = 0,160) e instável (p = 0,085). Conclusão: Indivíduos com FP obtiveram menores alcances no SEBT total, apresentando déficit de equilíbrio dinâmico e comprometimento no desempenho funcional quando comparados com os participantes saudáveis.

Abstract Introduction: Plantar fasciitis (PF) is characterized by non-inflammatory degeneration and pain under the heel, and is one of the most common foot complaints. The compensations and adjustments made to decrease the discomfort caused by the disease are clinical findings and can be a factor that contributes to impaired balance and decreased functional performance. Objective: To compare functional performance as well as static and dynamic balance among subjects with and without PF. Methods: The sample consisted of 124 subjects of both sexes aged 20-60 years. Participants were divided into two groups: a bilateral PF group (PFG; n = 62) and a control group (CG, n = 62). The following outcomes were analyzed: static and dynamic balance (using functional tests) and functional performance (using a questionnaire). We used Student’s t test for independent samples to compare variables between the groups. The alpha error was set at 0.05. Results: Subjects with PF showed greater impairment in their overall dynamic balance performance (p < 0.001) than the control group, except for left posteromedial movement (p = 0.19). The CG showed showed better functional performance (p < 0.001) than the PF group. There was no difference between groups for the variable static balance on stable (p = 0.160) and unstable surfaces (p = 0.085). Conclusion: Subjects with PF displayed smaller reach distances in the overall Star Excursion Balance Test (SEBT), demonstrating a deficit in dynamic balance and functional performance when compared with healthy subjects.
