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.

对于美国估计有200万人来说，保持健康的生活方式可能很困难 依靠手动轮椅来保证行动能力和独立性的人。虽然具体的健康挑战 对于每一个轮椅使用者取决于他们的伤害或损害的性质，一些最常见的 问题是：1）由于体力活动减少而引起的并发症，2）由于重复压力而引起的并发症 受伤，3）由于获得有限的轮椅技能而引起的并发症，以及4）由于 轮椅部件故障或退化。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，这些并发症往往是紧密的， 再加上，要求用户在多个维度上形成健康的习惯，以便在 长期.技术可以帮助轮椅使用者养成良好的习惯，保持身体活动，避免 强调伤害，发展他们的轮椅技能，并维护他们的轮椅，但没有商业产品 解决这些相互关联的健康挑战的现有机制。我们建议在第一阶段SBIR中 为轮椅使用者开发和试点测试综合健康系统。MiGo-Wheels将 为用户提供活动目标，促进健康的推进习惯，并奖励轮椅技能 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，类似于汽车中的检查引擎灯。MiGo-Wheels将由 一个由三个设备组成的无线网络：1）一个腕戴式活动手表，它将检测推压，测量 时空推动特性，并提供视觉反馈，2）安装在轮椅上的传感器， 测量轮椅的航向、倾斜角度和加速度，以及3）安装在轮子上的传感器， 测量轮椅轮子的角速度。MiGo-Wheels还将包括一个智能手机应用程序 （在第二阶段开发），允许用户查看一段时间内的性能趋势， 和通知，与其他轮椅使用者连接，并控制设备设置。我们的假设是 这种综合方法将使轮椅使用者能够以一种 综合和可持续的方式，从而减少广泛的负面健康的发生率 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：开发原型轮椅和轮式 探头单位（1-3个月）。目标2：开发用于监测一套综合轮椅的算法 活动和维护数据（2-4个月）。目标3：进行实验室内初步研究（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，它将是第一步， 开发一种有价值的新工具，帮助轮椅使用者改善整体健康状况。
