The objective of this award is to establish an international research and education partnership between the University of Michigan (U-M) and University of Bologna (UniBo) in Italy. The proposed work is envisioned to improve the quality-of-life of people with disabilities and their caregivers, transform the knee-ankle-foot-orthosis care to data-based diagnosis and model-based design and 3D-printing, and provide an international research experience to students. The goal of this collaboration is to provide a high-quality international research experience to University of Michigan students to increase student diversity and retention and advance students' ability in and knowledge of culture, globalization, leadership, teamwork, and communication. The key intellectual merit of this collaboration is in the model-based design, 3D-printing, and evaluation of individualized assistive devices. The project will utilize technical knowledge gained from University of Michigan and will improve individualized assistive devices such as the knee-ankle-foot orthosis, a brace that helps people with leg instabilities to walk. The scientific objective of this award is to establish an international research and education partnership between the University of Michigan (U-M) and University of Bologna (UniBo) in Italy on the model-based design, 3D-printing, and evaluation of individualized assistive devices (IADs). The project is focused on the advancements in 3D-printing and wearable sensors that enable the design and fabrication of assistive devices for individual needs. Patient-specific biomechanical models will be developed to analyze the motions and forces associated with the daily activities of a patient. For example, from models of patient-specific knee joint motion, compliant 3D-printed knee joints will be analyzed and designed to improve the function of individual assistive devices. Combined metal 3D-printing, precision machining, and mechanical testing will be used to fabricate and test the compliant knee joint. Finally, the knee-ankle-foot-orthosis devices fabricated by conventional and 3D-printing methods will be evaluated on patients in clinic and during daily activities. Specifically, this project aims to design, fabricate, and evaluate an individualized knee-ankle-foot-orthosis (KAFO) with metal and plastic 3D-printed parts. Students will study four research topics related to the KAFO: (1) biomechanical quantification of activities and lifestyles of KAFO patients, (2) analysis and design of a patient-specific compliant knee joint, (3) manufacturing of compliant knee joint, and (4) evaluation of the patient-specific KAFO.The broader impact of the proposed work in design, 3D-printing, and evaluation of personalized assistive devices is to re-establish the quality-of-life of people with disabilities by restoring normal joint motion and function. Personalized assistive devices with good fit and quick delivery can greatly benefit patients as well as their caregivers. Further, tailoring the function of these devices to the patient improves their ability to ambulate and reduces the chances of reinjury. The transformative aspects of this project are the mass production of custom assistive devices and the long-term monitoring of the gait and mobility of assistive device users for physical and psychological diagnosis and prevention of fall and other accidents. The knowledge and biomechanical models can improve the design practice and evaluation of the efficacy of a broad range of assistive devices.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项的目的是建立密歇根大学（U-M）和意大利博洛尼亚大学（UNIBO）之间的国际研究和教育合作伙伴关系。 设想拟议的工作是为了改善残疾人及其护理人员的生活质量，将膝盖障碍的次病护理转变为基于数据的诊断和基于模型的设计和3D打印，并为学生提供国际研究经验。这项合作的目的是为密歇根大学学生提供高质量的国际研究经验，以提高学生多样性和保留，并提高学生在文化，全球化，领导力，团队合作和沟通方面的能力和知识。这种合作的主要知识优点是基于模型的设计，3D打印以及对个性化辅助设备的评估。该项目将利用从密歇根大学获得的技术知识，并将改善个性化的辅助设备，例如膝盖骨骼矫形器，该设备可以帮助有腿不稳定的人走路。该奖项的科学目标是在意大利建立密歇根大学（U-M）和博洛尼亚大学（UNIBO）之间的国际研究和教育合作伙伴关系，该研究对基于型号的设计，3D打印，以及对个性化辅助设备（IADS）的评估。该项目的重点是3D打印和可穿戴传感器的进步，这些传感器可以为个人需求设计和制造辅助设备。 将开发患者特异性的生物力学模型，以分析与患者日常活动相关的运动和力。例如，从患者特异性膝关节运动的模型中，将分析兼容的3D打印膝关节，并设计以提高单个辅助设备的功能。 合并的金属3D打印，精确加工和机械测试将用于制造和测试兼容的膝关节。 最后，将对诊所和日常活动中的患者进行常规和3D打印方法制造的膝盖 - 骨骼正直手段。具体而言，该项目旨在使用金属和塑料3D打印的零件设计，制造和评估个性化的膝盖骨骼正犯（KAFO）。 Students will study four research topics related to the KAFO: (1) biomechanical quantification of activities and lifestyles of KAFO patients, (2) analysis and design of a patient-specific compliant knee joint, (3) manufacturing of compliant knee joint, and (4) evaluation of the patient-specific KAFO.The broader impact of the proposed work in design, 3D-printing, and evaluation of personalized assistive devices is to re-establish the通过恢复正常的联合运动和功能，残疾人的生活质量。具有良好合身和快速交付的个性化辅助设备可以极大地使患者及其护理人员受益。此外，根据患者的身份调整这些设备的功能可以提高他们的行动能力并减少重伤的机会。该项目的变革性方面是大规模生产定制辅助设备，以及对辅助设备使用者的步态和流动性的长期监控，用于身体和心理诊断，预防跌倒和其他事故。知识和生物力学模型可以改善各种辅助设备的功效的设计实践和评估。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，认为值得通过评估来获得支持。
