Amputees from underdeveloped and developing regions have limited access to prosthetic devices. In this scenario, collaborative groups arise for the development of low-cost prosthetics devices, made by 3D printing, with open source distribution, aiming the access and improvement of the life quality on economically disadvantaged populations, on a global scale. In this perspective, the objective of this study was to analyze the characteristics related to the human factors and ergonomics, present in the design of open source prostheses for the upper limbs. The documentary study had as subjects 9 projects conveyed by the ENabling The Future website. In addition, the human factors and ergonomics of the devices, although present in the designs, are lack in consistent and can imply in the user's use and engagement with the devices. However, the open source prostheses are coherent design projects considering the contexts and objectives their are intended, being able to act as an accessible alternative to conventional prostheses, enabling the accomplishment of daily life activities of a considerable part of the population.
A atenção aos aspectos ergonômicos no desenvolvimento das órteses customizadas permite a adequação destes dispositivos à geometria das sessões do corpo de um indivíduo específico, às debilidades que se pretende corrigir e às tarefas a serem realizadas com apoio do dispositivo. Nesse contexto, o objetivo deste estudo foi o de identificar processos autorais de especialistas para o desenvolvimento e fabricação de órteses customizadas, identificando as etapas, tecnologias e os meios de fabricação utilizados. Para tal, realizou-se uma revisão bibliográfica sistematizada, na qual foram selecionados 05 estudos que apresentam processos próprios de desenvolvimento de órteses customizadas. Foram detectados os seguintes pontos focais: 1. A automatização do processo 2. A utilização de novas tecnologias não invasivas na obtenção de dados antropométricos (como scanners 3D e Tomografia Computadorizada) que permitem liberdade de criação em softwares CAD. 3. A tarefa a ser realizada. 4. Redução das etapas e do tempo consumido nas mesmas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
