The research plan proposes to test an orthotic bracing platform that eliminates sidebars. The principal investigator received a patent for an orthotic joint that eliminates sidebars by incorporating the stops and locks into the proprietary laminating technique. Some benefits offered by such a system are lighter weight, better comfort and cosmesis, and lower fabrication costs. Steel with aluminum sidebars are currently the most prevalent mechanical joint materials used in knee orthoses. This study could demonstrate feasibility and benefit of sidebarless bracing. Additionally, developmental aim is to achieve orthoses with optimum functional support and highest level of comfort for the user, and optimum strength of the device itself. Mechanical strength testing of orthoses and testing of biomechanical functionality will be conducted on subject orthoses and commercially available orthoses using a surrogate leg, at The Thayer School of Engineering at Dartmouth College. The Biomotion Laboratory at Massachusetts General Hospital, in Boston, will conduct a human study. The human study will include a subjective quality rating of orthoses tested because of importance of orthoses acceptability for patient compliance. Data accumulated will also determine any changes necessary in the basic stopping/locking motion joint design and laminating technique that will further optimize commercialization potential. PROPOSED COMMERCIAL APPLICATIONS: There are over one million clients wearing rigid functional knee orthoses and many more that have knee joints that cross the knee in other types of orthoses. These clients could benefit from a lighter, more tailored, less bulky sidebarless orthotic system. The proposed patented knee joint uses composite reinforcement instead of sidebars.

该研究计划建议测试一种消除侧杠的矫形支撑平台。 首席研究员获得了一项矫形关节专利，该矫形关节通过将止动件和锁结合到专有的层压技术中来消除侧杆。 这种系统带来的一些好处是重量更轻、舒适度和美观性更好，以及制造成本更低。 钢与铝侧杆是目前膝关节矫形器中最普遍使用的机械关节材料。 这项研究可以证明无侧杆支撑的可行性和好处。此外，开发目标是实现为用户提供最佳功能支撑和最高舒适度以及设备本身最佳强度的矫形器。达特茅斯学院塞耶工程学院将使用代腿对受试矫形器和市售矫形器进行矫形器机械强度测试和生物力学功能测试。 波士顿马萨诸塞州总医院的生物运动实验室将进行一项人体研究。由于矫形器可接受性对于患者依从性的重要性，人体研究将包括对所测试的矫形器的主观质量评级。积累的数据还将确定基本停止/锁定运动接头设计和层压技术所需的任何改变，这将进一步优化商业化潜力。拟议的商业应用：有超过一百万的客户佩戴刚性功能性膝关节矫形器，还有更多的客户拥有与其他类型矫形器交叉的膝关节。这些客户可以受益于更轻、更定制、体积更小的无侧杆矫形系统。 拟议的专利膝关节使用复合材料加固代替侧杆。
