Ankle and foot orthotics play a pivotal role in the rehabilitation of individuals who have suffered a stroke, aiding in the restoration of their gait and overall mobility. However, optimizing the effectiveness of these orthoses requires a personalized approach that takes into account each patient’s unique biomechanical characteristics. This study delves into the innovative use of carbon fiber combined with cost-effective 3-D printing technology to craft custom foot plate orthoses for individuals with partial foot amputations. The core of this investigation revolves around the development, testing, and validation of a novel prosthetic foot plate. To ensure precision in design and performance, the study begins by modeling the human foot as a finite element (FE) model, replicating the dimensions of a UK7- sized foot with a 2 mm thickness. This FE model serves as the foundation for the creation of the foot plate, enabling theoretical predictions and empirical assessments to be conducted with scientific rigor. One of the most significant findings of this research is the remarkable efficiency of carbon fiber in extending the length of the legs and mitigating strain on the delicate distal ends of the feet. By redistributing the weight to other areas of the foot or leg, the carbon fiber foot plate offers a breakthrough solution for enhancing balance, stability, and comfort for individuals with partial foot amputations. In summary, this study showcases the transformative potential of carbon fiber and 3-D printing in the realm of ankle and foot orthotics, with a particular focus on individuals with partial foot amputations. Through meticulous design, testing, and validation, the research underscores the importance of tailored orthotic solutions and offers a promising pathway towards optimizing gait rehabilitation and overall mobility for a diverse patient population.
