Abstract(s)
A amputação pode ser descrita como a extração de uma extremidade do corpo, que pode
ocorrer por diversos motivos, como traumatismos, neoplasia ou doenças vasculares ou
infeciosas. Atualmente o número de amputados do membro superior é bastante
considerável, dando a esta matéria uma crescente busca de alternativas que ajudem o
paciente, pelo menos, a executar as tarefas diárias básicas. O desenvolvimento e pesquisa
de vários tipos de próteses têm sido muito ativos, sendo um dos mais procurados a prótese
mioelétrica. Como tal, é necessário que estas próteses, dado ao seu objetivo, sejam bem
dimensionadas, sobretudo na parte do processo de aquisição de dados e da sinergia do
músculo com a prótese. O objetivo principal desta dissertação é o estudo dos mais
importantes elementos a considerar para a boa ligação prótese-músculo, bem como a
escolha das opções mais viáveis a aplicar no trabalho. Esta dissertação termina com o
projeto de dois sistemas de controlo e aquisição de dados no qual é implementado o controlo
de limite.
The amputation can be described as the extraction of a body extremity, which can occur for multiple reasons, like injuries, neoplasm, or vascular/infectious diseases. Nowadays the number of upper limb amputees is quite considerable, giving this matter a growing search for alternatives that help the patient, at least, to perform daily basic tasks. The development and research of multiple kinds of prosthesis have been very active, being the myoelectric prosthesis one of the most requested. As such, it is necessary that these prostheses, given their objective, are well dimensioned, especially in the part of the process of data acquisition and prosthesis-muscle synergy. The main objective of this dissertation will be the study of the most important factors to consider for a good prosthesis-muscle connection, as well as the choice of the most viable options to apply in the work. This dissertation ends with the design of two control and data acquisition systems in which limit control is implemented.
