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.

许多接受下肢截肢的退伍军人在处理假肢方面存在困难。 因残肢感觉减退、认知问题或感觉不足而适合插座 训练。尽管他们被指示补偿残肢的变化 全天使用假体袜子，许多退伍军人花了很大一部分 假肢插座不合适，可能会导致大量皮肤 问题、不适和痛苦。这个项目的目标是开发和测试一个套接字- FIT传感系统，可以适应患者特定的肢体体积变化，并可以 帮助退伍军人在截肢后康复护理期间自我管理他们的牙槽适合性。 贴合插槽的感应系统可以检测到退伍军人穿得太少或太多 许多袜子，并可以在需要添加或移除时谨慎地提醒退伍军人 假体袜子。 在本项目中，我们将追求以下两个具体目标：1)改进插座贴合 2)测试插座适配性检测算法。我们将完善这一制度 利用经验丰富的假肢使用者和临床医生的反馈，我们将 在三名退伍军人的截肢后康复护理期间测试该系统。 这个项目将创建一个简单易用的工具来帮助退伍军人进行下肢截肢 自我管理假体插座适合。这个工具将对退伍军人特别有益， 康复的早期阶段，将有助于减少可预防的疼痛、不适、 以及与插座适合性差的常见皮肤问题。我们相信这个项目将加强 凭借自我管理插座贴合的资深员工参与度最终将增加 假体使用和社区参与。
