PROJECT SUMMARY Lower limb amputees rely on prosthetic sockets as the interface with their prosthetic legs. The prosthetic sockets only work well if they fit residual limbs of amputees perfectly. Unfitted sockets cause various health issues for lower limb amputees and could significantly limit amputees’ functionality. Currently, prosthetists lack the capability to diagnose socket fit during the socket fitting procedure, which limits their capability to customize the sockets for better fit. The proposed Easy-to-use, iNtelligent, Affordable LinEr (ENABLE) System for Socket Fit Assessment（ENABLE） system will be used as a diagnosis tool for prosthetists. Based on a novel material, which changes color based on loaded pressure, this Enable system will permit prosthetists to evaluate the socket fit by observing the pressure distribution on the residual limb directly. During the proposed project, we will develop the smart liner system and test it through both bench tests and human subject tests. We will also validate that prosthetists will be able to use the smart liner to make appropriate socket fit diagnosis through simulated clinical cases.

项目总结 下肢截肢者依靠假肢插座作为假肢与假肢的接口。假体插座 只有在完全适合截肢者的残肢时，它们才能起到很好的作用。未安装的插座会导致各种健康问题 这可能会严重限制截肢者的功能。目前，假肢医生缺乏 在插座装配过程中诊断插座适配性的能力，这限制了他们定制的能力 插座，以便更好地贴合。拟议的易于使用、智能、经济实惠的插座衬垫(Enable)系统 Fit评估(Enable)系统将被用作假肢医生的诊断工具。基于一种新材料， 它根据加载的压力改变颜色，该启用系统将允许修复师评估插座 通过直接观察残肢上的压力分布进行拟合。在拟议的项目期间，我们将 开发智能衬垫系统，并通过台架测试和人体测试对其进行测试。我们还将验证 假肢医生将能够使用智能衬垫通过模拟进行适当的插座匹配诊断 临床病例。
