项目摘要

DESCRIPTION (provided by applicant): The public health problem addressed by this proposal is that inactivity in individuals with chronic disabilities who use a wheelchair results in signifiant and costly secondary complications, such as pressure ulcers, obesity, diabetes, osteoporosis, and cardiovascular comorbidities. We propose an interactive telehealth monitoring and auto-biofeedback system to promote physical activity, pressure relief maneuver performance, and self-management among wheelchair users. In this project we focus on patients with spinal cord injury (SCI) who are at particularly high risk for developing pressure ulcers from sitting too long (31% annual incidence, 85% lifetime incidence). However, the proposed technology is broadly applicable to wheelchair based telehealth. The proposed technology - which attaches to any wheelchair without modification - has three core components: 1) an activity monitoring system (i.e., wheelchair speed, distance travelled, and number of self-propulsions), 2) a pressure relief monitoring system, and 3) a system that provides reminders and feedback regarding the achievement of pressure relief and physical activity goals. Biofeedback will be delivered locally (to the user) via a wheelchair mounted display and remotely (to the clinician) via a secure internet interface. The enabling technologies are innovative sensor systems to monitor wheelchair specific activity patterns but the significant value comes from integrating these novel measurements within biofeedback system that encourages wheelchair users to actively avoid secondary complications of inactivity and allows care providers to identify at risk patients and intervene efficiently. Existing technologies do not compare with the proposed solution. Products exist to monitor wheelchair seat pressure but these products are costly, cumbersome, and not designed for home use. Products exist to monitor wheelchair specific physical activity but these devices cannot distinguish passive from active wheelchair movement. No existing technology combines these measures with auto-biofeedback and telehealth functionality. The team we have assembled for this collaborative project includes engineers, clinicians, and scientists from BioSensics (a privately held biomedical technology development company) and Rancho Los Amigos National Rehabilitation Center (one of the largest comprehensive rehabilitation centers in the United States). In addition, this project benefits from the consultation of a world-renowned expert in physical activity monitoring (Dr. Bijan Najafi, University of Arizona), as well as a leading expert and critical decision maker in SCI care (Dr. Sophia Chun, Chief of SCI, Veterans Health Administration). This team has collaborated successfully on prior projects. The Specific Aims of Phase I are to 1) improve prototyped and pilot tested versions of the proposed system by leveraging existing BioSensics technologies commercialized through prior NIH SBIR awards; 2) validate the measurements of the proposed system using state-of-the-art tools including a high-density pressure mat and camera-based motion capture, and 3) evaluate the efficacy of local biofeedback (to the user via a wheelchair mounted display) during community usage. By demonstrating that biofeedback increases physical activity and achievement of pressure relief will justify further NIH investment in the proposed technology. Within 6 months of the completion of Phase I, we anticipate having a commercially available beta release of the system (BioSensics has successfully brought several products to market in this timeframe). In Phase II we will develop the remote monitoring and telehealth aspects of the proposed system by adding automatic wireless data transfer capabilities (via mobile and Wi-Fi networks) and developing a secure website for remotely accessing activity data and sending telehealth reminders to the wheelchair mounted display.

描述（由申请人提供）：该提案解决的公共卫生问题是，使用轮椅的慢性残疾患者的不活动导致象征性和昂贵的继发性并发症，例如压溃疡，肥胖，糖尿病，骨质疏松症和心血管疾病。我们提出了一种交互式远程医疗监控和自动型型式背式系统，以促进轮椅使用者之间的体育活动，减压操纵性能和自我管理。在这个项目中，我们专注于脊髓损伤（SCI）的患者，这些患者因坐太久而出现压力溃疡的风险特别高（每年31％，终生发病率85％）。但是，拟议的技术广泛适用于基于轮椅的远程医疗。所提出的技术 - 无需修改的任何轮椅 - 具有三个核心组成部分：1）活动监控系统（即轮椅速度，距离，旅行距离和自我启动的数量），2）压力缓解监控系统，3）一个系统，该系统提供了有关压力缓解和体育锻炼目标的提醒和反馈。生物反馈将通过轮椅安装的显示屏在本地（用户）交付，并通过安全的Internet界面远程（临床医生）交付。支持技术是创新的传感器系统可以监视轮椅特定的活动模式，但重大价值来自将这些新颖的测量结果整合到生物反馈系统中，该测量结果鼓励轮椅使用者主动避免避免使用不活动的次要并发症，并允许护理提供者在风险患者处识别和有效介入。现有技术与建议的解决方案不相比。存在用于监视轮椅座椅压力的产品，但这些产品昂贵，繁琐，并且不是为家庭使用而设计的。存在用于监视轮椅特异性体育锻炼的产品，但这些设备无法将被动式轮椅运动区分开。没有现有技术将这些措施与自动反馈和远程医疗功能相结合。我们为这个合作项目组成的团队包括生物敏感学（私有生物医学技术开发公司）的工程师，临床医生和科学家和Rancho Los Amigos国家康复中心（美国最大的综合康复中心之一）。此外，该项目受益于世界知名的咨询体育活动监测专家（亚利桑那大学Bijan Najafi博士）以及SCI Care的领先专家和关键决策者（Sophia Chun博士，SCI，退伍军人健康管理局负责人）。该团队已成功地在先前的项目上合作。第一阶段的具体目的是1）通过利用现有的通过先前的NIH SBIR奖项商业化的现有生物密度技术来改善所提出系统的原型和试点测试版本； 2）使用最先进的工具（包括高密度压力垫和基于摄像头的运动捕获）验证提出的系统的测量值，3）在社区使用过程中评估本地生物反馈（通过轮椅安装的显示器对用户）的功效。通过证明生物反馈可以增加体育活动并实现升压的实现将证明对拟议技术的进一步投资是合理的。在第一阶段完成后的6个月内，我们预计该系统的商业可用Beta版本（在此期限内成功地将多种产品推向市场）。在第二阶段，我们将通过添加自动无线数据传输功能（通过移动和Wi-Fi网络）并开发一个安全的网站来开发拟议系统的远程监视和远程医疗方面，以远程访问活动数据并将Telethealth提醒发送到轮椅上。
