Resumo: | Introduction – The piston effect is one of the main problems regarding the effectiveness of prostheses. A decrease in the piston effect can lead to a more natural gait by increasing proprioceptivity. Objectives – Check if there is a difference in piston effect values between various suspension systems for a transtibial prosthesis with the use of Liners, and test the application of imaging tests in the analysis of the better prosthetic solution for a particular individual. Methods – Radiography of the prosthesis, in charge, in the orthostatic position, keeping the weight of the amputee equally distributed on both feet. Then was held another x-ray in the sagittal plane with the knee flexed at 30° with a weight of 5kg applied at the distal end of the prosthesis for 30 sec. After these two exams, the measurements for each type of suspension system were taken. Results – Of the four studied systems only three have piston values since one of the systems did not create enough suspension to withstand the weight placed on the distal end of the prosthesis. Through the radiology exams performed, measurements of the three systems could find piston effect variations ranging from 47.91mm to 72.55mm. Conclusion – By performing the imaging study there were differences at the level of the piston effect in the various suspension systems, proving that this is a viable tool in the evaluation of the piston effect. Also through the analysis of the results was notorious that the suspension system Vacuum Assisted Suspension System (VASS) is what presents less piston effect. |

Uma diminuição do mesmo pode levar a uma marcha mais natural através do aumento da propriocetividade. Objetivos – Verificar se existe diferença de valores do efeito de êmbolo entre vários sistemas de suspensão para próteses transtibiais com a utilização de Liners e testar a aplicação de testes de imagiologia na análise da melhor solução protésica para um determinado indivíduo. Metodologia – Foi obtida uma radiografia da prótese em carga na posição ortostática, mantendo o peso do indivíduo igualmente distribuído pelos dois pés. Seguidamente foi realizada outra radiografia no plano sagital com o joelho com 30° de flexão, com a prótese suspensa e um peso de 5kg aplicado na extremidade distal da mesma durante 30 seg. Através destes dois exames efetuaram-se as medições do êmbolo para cada tipo de sistema de suspensão. Resultados – Dos quatro sistemas estudados apenas três apresentam valores de êmbolo, visto que um dos sistemas não criou suspensão suficiente para suportar o peso colocado na extremidade distal da prótese. Através das medições realizadas nos exames imagiológicos dos três sistemas pudemos encontrar variações de efeito de êmbolo que vão dos 47,91mm aos 72,55mm. Conclusão – Através da realização do estudo imagiológico verificaram-se diferenças a nível do efeito de êmbolo nos vários sistemas de suspensão, provando que esta é uma ferramenta viável na avaliação do mesmo. Também através da análise dos resultados ficou notório que o sistema de suspensão Vacuum Assisted Suspention System (VASS) é o que apresenta menos êmbolo.Escola Superior de Tecnologia da Saúde de Lisboa (Instituto Politécnico de Lisboa)2022-09-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.25758/may.1184oai:journals.ipl.pt:article/628Saúde e Tecnologia; No. 13 (2015): Maio 2015; 27-33Saúde & Tecnologia; N.º 13 (2015): Maio 2015; 27-331646-9704reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://journals.ipl.pt/stecnologia/article/view/628https://doi.org/10.25758/may.1184https://journals.ipl.pt/stecnologia/article/view/628/523Direitos de Autor (c) 2022 Saúde & Tecnologiainfo:eu-repo/semantics/openAccessMatos, José FulgêncioBriôa, MárioCunha, GildaEiras, MargaridaRibeiro, Margarida2022-12-20T10:59:04Zoai:journals.ipl.pt:article/628Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:21:25.481978Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
