An Easy-to-use, iNtelligent, Affordable LinEr (ENABLE) System for Socket Fit Assessment

项目概要 下肢截肢者依靠假肢接受腔作为与假肢的接口。假肢接受腔 只有完美贴合截肢者的残肢才能发挥作用。不合适的插座会导致各种健康问题 下肢截肢者可能会严重限制截肢者的功能。目前，假肢师缺乏 在插座安装过程中诊断插座安装的能力，这限制了他们定制的能力 插座以便更好地配合。拟议的易于使用、智能、经济实惠的 LinEr (ENABLE) 套接字系统 适合度评估（ENABLE）系统将作为假肢医师的诊断工具。基于一种新颖的材料， 根据负载压力改变颜色，该启用系统将允许假肢师评估接受腔 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 开发智能衬里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 假肢师将能够使用智能衬管通过模拟进行适当的接受腔配合诊断 临床病例。

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.
