Sensor system for self-management of prosthetic socket fit

许多下肢截肢的退伍军人很难管理他们的假肢 由于残肢感觉降低、认知问题或不充分 训练虽然他们被指示补偿残肢的变化， 大量的全天使用假肢袜子，许多退伍军人花费大量 一天中有一个不合适的假肢接受腔，这可能导致许多皮肤 问题、不适和疼痛。这个项目的目标是开发和测试一个套接字- 适配感测系统，其可以适应患者特定的肢体体积变化，并且可以 帮助退伍军人在截肢后康复护理期间自我管理其接受腔配合。 插座式传感系统可以检测退伍军人何时穿得太少或太多 许多袜子，并可以离散提醒退伍军人时，他们需要添加或删除 假肢袜 在这个项目中，我们将追求以下两个具体目标：1）完善插座配合 传感系统和2）测试插座配合检测算法。我们将完善系统 使用经验丰富的退伍军人假肢用户和临床医生的反馈，我们将 在截肢后康复护理期间，用三名退伍军人测试该系统。 该项目将创建一个易于使用的工具，以帮助退伍军人下肢截肢 自我管理假肢接受腔适配。这个工具将特别有利于退伍军人在 在康复的早期阶段，将有助于减少可预防的疼痛，不适， 以及插座配合不良常见的皮肤问题。我们相信这个项目将提高 通过自我管理的插座适配， 假肢使用和社区参与。

Many Veterans with lower-limb amputations have difficulty managing their prosthetic socket fit due to reduced sensation in their residual limb, cognitive issues, or insufficient training. Although they are instructed to compensate for changes in residual limb volume throughout the day using prosthetic socks, many Veterans spend large portions of the day with a poorly fitting prosthetic socket, which can lead to numerous skin problems, discomfort, and pain. The goal of this project is to develop and test a socket- fit sensing system that can adapt to patient-specific changes in limb volume and can help Veterans self-manage their socket fit during post-amputation rehabilitation care. The socket-fit sensing system can detect when the Veteran is wearing too few or too many socks and can discretely alert the Veteran when they need to add or remove prosthetic socks. In this project, we will pursue the following two specific aims: 1) refine the socket-fit sensing system and 2) test socket-fit-detection algorithms. We will refine the system using feedback from experienced Veteran prosthesis users and clinicians, and we will test the system with three Veterans during their post-amputation rehabilitation care. This project will create an easy-to-use tool to help Veterans with lower-limb amputations self-manage prosthetic socket fit. This tool will be especially beneficial for Veterans at an early stage in their rehabilitation and will help reduce preventable pain, discomfort, and skin issues common with poor socket-fit. We believe this project will enhance Veteran engagement with self-managing socket fit and ultimately will increase prosthesis use and community participation.
