MiGo-Wheels: A comprehensive feedback system to help wheelchair users maintain a healthy lifestyle

对于美国大约200万人来说，保持健康的生活方式可能很困难 他们依靠手动轮椅来获得灵活性和独立性。尽管具体的健康挑战 对于每个轮椅使用者来说，取决于他们受伤或受损的性质，其中一些最常见的 问题是：1)体力活动减少引起的并发症，2)反复应激引起的并发症 受伤，3)有限的轮椅技能获得引起的并发症，以及4)由于 轮椅部件发生故障或损坏。这些并发症中的许多可以通过 生活方式的适应和健康习惯的形成。然而，这些并发症通常是紧密的 再加上，需要用户在多个维度养成健康的习惯，以便在 从长远来看。科技可以帮助轮椅使用者养成健康的习惯，保持身体活动，避免 强调受伤，发展轮椅技能，维护轮椅，但没有商业产品 目前存在解决这些相互关联的卫生挑战的办法。在此阶段，我们建议使用SBIR 为轮椅使用者开发和试行综合健康系统。迷你轮将会 为用户提供活动目标，倡导健康推进习惯，奖励轮椅技能 发展。最后，为了保持最佳的轮椅性能，它将检测并提醒用户 潜在的轮椅性能问题，类似于汽车上的检查引擎灯。迷你轮将由 由三个设备组成的无线网络：1)戴在手腕上的活动手表，它将检测按压、测量 时空推送特性，并提供视觉反馈，2)安装在轮椅上的传感器将 测量轮椅的方向、倾角和加速度，以及3)安装在轮椅上的传感器，它将 测量轮椅轮子的角速度。Migo-Wheels还将包括一款智能手机应用程序 (在第二阶段开发)允许用户查看一段时间内的性能趋势，接收其他反馈 和通知，与其他轮椅用户连接，并控制设备设置。我们的假设是 这一全面的方法将使轮椅用户能够在 以综合和可持续的方式，从而减少大范围负面健康的发生率 与轮椅使用相关的影响。可行性测试将与 兰乔·洛斯阿米戈斯康复中心。目标1：开发轮椅和轮椅原型 传感器单元(1-3个月)。目标2：开发监控全套轮椅的算法 活动和维护数据(2-4个月)。目标3：进行实验室试点研究(N=20名轮椅使用者) 验证Migo-Wheels的可行性(5-6个月)。如果这个项目成功，这将是 开发一种有价值的新工具，帮助轮椅使用者改善他们的整体健康状况。

Maintaining a healthy lifestyle can be difficult for the estimated 2 million people in the United States who rely on manual wheelchairs for mobility and independence. Although the specific health challenges for every wheelchair user depend on the nature of their injury or impairment, some of the most common issues are: 1) complications due to reduced physical activity, 2) complications due to repetitive stress injuries, 3) complications arising from limited acquisition of wheelchair skills, and 4) complications due to wheelchair component failure or deterioration. Many of these complications can be managed through lifestyle adaptation and the formation of healthy habits. However, these complications are often tightly coupled, requiring users to form healthy habits in multiple dimensions in order to manage them over the long term. Technology could help wheelchair users form robust habits to stay physically active, avoid stress injuries, develop their wheelchair skills, and maintain their wheelchair, but no commercial product currently exists that addresses these interconnected health challenges. We propose in this Phase I SBIR to develop and pilot test a comprehensive wellness system for wheelchair users. MiGo-Wheels will provide users with activity goals, promote healthy propulsion habits, and reward wheelchair skill development. Finally, to maintain optimal wheelchair performance, it will detect and alert the user to potential wheelchair performance issues, similar to a check engine light in a car. MiGo-Wheels will consist of a wireless network of three devices: 1) a wrist-worn activity watch that will detect pushes, measure spatiotemporal push characteristics, and deliver visual feedback, 2) a wheelchair mounted sensor that will measure the wheelchair’s heading, tilt angle, and acceleration, and 3) a wheel-mounted sensor that will measure angular velocity of the wheelchair’s wheel. MiGo-Wheels will also include a smartphone app (developed in Phase II) to allow users to view performance trends over time, receive additional feedback and notifications, connect with other wheelchair users, and control device settings. Our hypothesis is that this comprehensive approach will enable wheelchair users to manage their health challenges in an integrated and sustainable manner, thus reducing the incidence of the broad range of negative health effects associated with wheelchair use. Feasibility testing will be performed in collaboration with the Rancho Los Amigos Rehabilitation Center. Aim 1: Develop prototype wheelchair and wheel-mounted sensor units (Months 1-3). Aim 2: Develop algorithms for monitoring a comprehensive set of wheelchair activity and maintenance data (Months 2-4). Aim 3: Perform in-lab pilot study (N=20 wheelchair users) to validate the feasibility of MiGo-Wheels (Months 5-6). If this project is successful, it will be the first step in developing a valuable new tool for helping wheelchair users improve their overall health.
