DEVELOPMENT OF A FULLY PERSONALIZED ORTHOSIS FOR CANINE REHABILITATION
| Resumo: | The rising population of companion dogs has driven an increasing demand for veterinary orthopedic innovations. Carpal hyperextension, a frequent and debilitating condition, compromises locomotion and overall quality of life. Orthoses represent a viable solution when surgery is not feasible due to anesthesia risks, comorbidities, or financial limitations. However, despite their potential, veterinary orthoses remain uncommon, mainly because of high costs, limited customization, and insufficient scientific validation. This dissertation describes the development of a patient-specific carpal orthosis, de- signed to stabilize the joint and improve mobility. The process was guided by a co-creation methodology, actively involving veterinarians, engineers, and pet owners, ensuring that both clinical and practical requirements were addressed. Instead of traditional casting, anatomical measurements and photographic documentation were used to digitally recon- struct the thoracic limb. Through a digital prototyping method, two design concepts were explored: a hybrid solution with rigid and flexible materials, and a fully flexible version intended to enhance comfort and adaptability. Finite Element Analysis (FEA) simulations were conducted on the rigid components, testing different materials (PET, ABS, and Nylon PA12) under gait-related loads. These analyses highlighted stress-prone regions, enabling targeted design refinements. The final orthosis combined rigidity for structural support with flexibility for comfort, successfully stabilizing the carpus in dorsiflexion, preventing collapse during ambulation, and ensuring safe weight distribution. Usability was further assessed through veterinary evaluation and standardized questionnaires, confirming both functionality and adaptability for daily use. This work demonstrates how additive manufacturing and co-creation can contribute to affordable, customized, and clinically effective veterinary orthoses. A standardized protocol was also established, facilitating reproducibility and broader application to future clinical cases of carpal instability. |

| dc.description.none.fl_str_mv | O aumento da população de cães de companhia tem impulsionado a procura por soluções ortopédicas inovadoras em veterinária. A hiperextensão do carpo, uma condição frequente e debilitante, compromete a locomoção e a qualidade de vida. As ortóteses surgem como alternativa viável à cirurgia quando esta não é possível devido a riscos anestésicos, comorbilidades ou limitações financeiras. No entanto, continuam pouco utilizadas devido aos custos elevados, falta de personalização e reduzida validação científica. Esta dissertação apresenta o desenvolvimento de uma ortótese personalizada para o carpo, concebida para estabilizar a articulação e restaurar a mobilidade. O processo seguiu uma metodologia de co-criação, envolvendo médicos veterinários, engenheiros e tutores, garantindo que as necessidades clínicas e práticas fossem satisfeitas. Em substituição da moldagem tradicional, utilizaram-se medições anatómicas e documentação fotográfica para a reconstrução digital do membro torácico. Dois conceitos de design foram testa- dos: um híbrido, combinando materiais rígidos e flexíveis, e outro totalmente flexível, privilegiando conforto e adaptação. As simulações de Análise por Elementos Finitos (FEA) foram aplicadas aos componen- tes rígidos, testando materiais como PET, ABS e Nylon PA12 sob cargas da marcha. Estas análises identificaram regiões críticas e orientaram melhorias no design. A ortótese final uniu rigidez para suporte estrutural e flexibilidade para conforto, estabilizando o carpo em dorsiflexão e prevenindo o colapso durante a locomoção. A usabilidade foi avaliada pelo veterinário e através de questionários estandardizados, confirmando funcionalidade e adequação para uso diário. Este trabalho demonstra como a fabricação aditiva e a co-criação permitem desenvolver ortóteses veterinárias acessíveis, personalizadas e eficazes. Foi ainda estabelecido um protocolo estandardizado para aplicação futura em casos clínicos de instabilidade do carpo. |
