Early in 1974, Wagner, J; Bourgois, R wrote the following in the article Biomechanical Study of the Hinge Knee Prosthesis: Preliminary Report: “Biomechanical study may eventually lead to prostheses that are more compatible with the muscles and skeleton and could eliminate such clinical problems as fractures or loosening”. Nowadays, one might not say eventually but definitely. Biomechanical analyses of prosthesis and orthosis have contribute for the design, evaluation and certification of these devices. Techniques such as numerical analysis and fatigue/load testing are also essential for this domain.
Thinking about this, we launch the GIBI, Research Group of BioInstrumentation, in collaboration with two research laboratories: LebM and GRANTE, both at the Federal University of Santa Catarina. Juliana Martins de Carvalho and I lead the group during its existence. Our goal was to research cutting-edge sensor and instrumentation systems for body applications (invasive or not). Currently, Juliana carries out the project, as I left to North America. Juliana recently finished her master thesis, where she developed a novel load cell, using strain gages, for spine prosthesis analysis.
