Artigo Completo:

O padrão de caminhada em indivíduos que apresentam disfunções musculares fomenta a demanda por dispositivos auxiliares de locomoção. Estes artefatos de assistência ao movimento variam de acordo com sua forma, tamanho e características funcionais, obedecendo às aplicações clínicas desejadas. Dentre as órteses de membro inferior, o Tutor Curto visa melhorar a capacidade do andar em indivíduos com limitações neuromusculares diversas, oferecendo níveis variados de suporte durante a marcha. O objetivo deste estudo é explorar a possibilidade de utilização de novos designs em Manufatura Aditiva para reproduzir a forma e as características funcionais de um Tutor Curto de forma eficaz. Para tanto, este trabalho apresenta um estudo sobre a atuação das forças mecânicas através da análise de Elementos Finitos em um tutor curto. Será apresentado o estudo de distribuição estresse decorrente do desenvolvimento da marcha, bem como o deslocamento do dispositivo ortopédico no decorrer da caminhada do paciente.

Orthosis and Finite Elements: a study for development of new designs through additive manufacturing Abstract: The gait pattern in people that present motor limitations foment the demand for auxiliary locomotion devices. These artifacts for movement assistance vary according to its shape, size and functional features, following the clinical applications desired. Among the ortheses of lower limbs, the ankle-foot orthesis aims to improve the ability to walk in people with different neuromuscular limitations, although they do not always answer patients' expectations for their aesthetic and functional characteristics. The purpose of this study is to explore the possibility of using new design in additive manufacturer to reproduce the shape and functional features of a ankle-foot orthesis in na efficient and modern way. Therefore, this work presents a study about the performance of the mechanical forces through the analysis of finite elements in an ankle-foot orthesis. It will be demonstrated a study of distribution of the stress on the orthopedic device in orthostatism and during the movement in the course of patient's walk.
