Résumé
Abstract Introduction Rheumatoid arthritis (RA) is a chronic, multisystem disease that involves synovial inflammation, leading to deformities, like finger ulnar deviation, pain and functional difficulties. The conservative treatment comprises orthoses, features added to the body that aims to correct deformity, reduce pain and improve functionality. In the market there are few kinetic/mobile orthosis models for correction of ulnar deviation in the fingers. However, users usually complain about increased palmar volume, presence of pressure points and functional loss, demonstrating the necessity to develop more effective orthoses. In this paper we introduce an innovative concept, of an original and articulate dynamic/kinetics orthosis, which aims to correct this finger deformity and encourage functionality. Methods Methodological procedures were divided into: Need Recognition; Specification Concept; Prototype and Validation. This paper deals with the last two stages of this research. Results A virtual orthosis prototype using CAD Solid Edge Insight™ was proposed. The orthosis developed consisted of 10 pieces, made of metal and resin with carbon fiber. Conclusion After virtual movement simulation, it was verified that the prototype allows for wrist and finger flexion/extension, the possibility of bilateral use, and provids ulnar deviation correction for the fingers. The final product is innovative and is easy to put on/off; volunteers claimed that the new prototype was satisfactory in terms of deformity correction.
Résumé
A destreza manual é uma habilidade fundamental para o desempenho das atividades cotidianas. Medidas da força muscular, amplitude de movimento e sensibilidade isoladamente podem não refletir o status funcional na avaliação físico-funcional. É importante também o uso de questionários autoaplicáveis e testes funcionais específicos que avaliem o desempenho levando em consideração o membro superior e que possam testar aspectos como a destreza, coordenação e qualidade da preensão, podendo variar em termos de padronização e propriedades psicométricas. A partir desta necessidade foi desenvolvido o Teste Funcional de Membro Superior Elui que visou oferecer um instrumento nacional de mensuração e de referência a ser utilizado na prática clínica, porém suas propriedades psicométricas ainda não são definidas. Objetivo: Analisar a confiabilidade interexaminador e teste re-teste do Teste Funcional de Membro Superior Elui. Método: 50 voluntários saudáveis, de ambos os sexos, com idade média de 32,62 anos que não apresentassem disfunção ou sintomatologia nos membros superiores foram submetidos ao teste por dois examinadores e após 30 dias por um examinador. A aplicação deste teste requer materiais simples presentes no cotidiano, divididos em 10 subitens: Simular Escrita, Virar Chave, Pegar pequenos objetos, Simular alimentação, Despejar água, Abrir Potes, Cortar com a Faca, Simular Vestuário, Pegar objetos Grandes e leves e Pegar objetos grandes e pesados. Cada voluntário avaliado deveria realizar cada item do teste com ambas as mãos ou com a mão dominante, dependendo do subitem analisado, sendo adaptada a lateralidade quando necessário. Resultados: A análise estatística foi realizada visando comparar as diferenças das medidas de cada sub-item do teste em segundos e a análise da confiabilidade interexaminadores e teste reteste pelo Coeficiente de Correlação Intraclasse (ICC) com intervalo de confiança de 95% e p < 0,05. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa local e todos os voluntários assinaram o termo de consentimento livre e esclarecido. Os resultados mostraram que com exceção da tarefa pegar pequenos objetos que teve ICC considerado não aceitável (0,65), todos os outros 9 itens apresentaram excelente confiabilidade interexaminadores entre 0,95-0,99 e Alpha de Cronbach entre 0,97-0,99. Para o teste reteste as tarefas com excelente confiabilidade foram despejar água ICC 0,98 e simular escrita ICC 0,91, boa confiabilidade para as tarefas pegar objetos grandes e pesados ICC 0,85, cortar com faca ICC 0,85 e simular alimentação ICC 0,80; confiabilidade aceitável dos itens virar chave ICC 0,74 e simular vestuário ICC 0,76; com Alpha de Cronbach de todas as tarefas entre 0,79 e 0,99. Conclusão: O Teste Elui apresentou excelente repetitividade tanto entre examinadores como em medidas repetidas ao longo do tempo pelo mesmo examinador na maioria dos subitens, sendo considerado confiável para a amostra estudada, sendo utilizada a terceira medida.
Manual dexterity is a key skill for the performance of everyday activities. Measurements of muscle strength, range of motion, and sensitivity alone may not reflect the functional status in assessing physical and functional conditions. It is also important to use self-applied assessments and specific functional tests to assess overall performance and test aspects such as dexterity, coordination and grasp quality, but these may differ in terms of standardization and psychometric properties. From this need we have developed the Elui Upper Extremity Functionality Test, with the intent to provide a national measuring instrument of the upper extremity and reference to be used in clinical practice, but its psychometric properties have not been yet defined. Objective: The aim of this study was to assess the inter-examiner reliability and test retest of the Elui Upper Extremity Functionality Test. Methods: Healthy volunteers (50) of both genders, with an average age of 32.62 years and no impairment or symptoms in the upper limbs were submitted to the test by two examiners and after 30 days by one examiner. The application of this test requires simple materials present in our everyday life, divided into 10 sub-items: Simulated writing, Turning a Key, Grasping small objects, Simulated feeding, Pouring water, Opening containers, Cutting with a knife, Simulated dressing, Grasping large and light objects, and Grasping large and heavy objects. Each volunteer evaluated should perform each item test with both hands or with the dominant hand, depending on the sub-item analyzed, and if needed, they adapted the laterality. Results: A statistical analysis was carried out to compare the differences in time measurements of each sub-item of the test in seconds. The analysis of the inter-examiner reliability and test-retest used the Interclass Correlation Coefficient (ICC) with a confidence interval of 95% and p < 0.05. The local Research Ethics Committee approved this study and all volunteers signed an informed consent form. With the exception of the Grasping small objects task, which had an unacceptable ICC (0.65), the results showed that all the other nine items had excellent inter-examiner reliability: between 0.95 and 0.99 and Cronbach's alpha between 0.97 and 0.99. For the test-retest, the tasks with excellent reliability were Pouring water ICC 0.98 and simulated writing with ICC 0.91, good reliability for the tasks Grasping large and heavy objects ICC 0.85, Cutting with a knife ICC 0.85 and Simulated feeding ICC 0.80; acceptable reliability for the items Turning a key ICC 0.74 and Simulated dressing ICC 0.76; with Cronbach's alpha of all tasks between 0.79 and 0.99. Conclusion: The Elui test showed excellent repeatability between examiners as well as with repeated measurements over time by the same examiner in most sub-items, being considered reliable for the studied sample using the third measurement.
