A seated exercise Internet of Things (IoT) device to enhance compliance rates for cardiac rehabilitation

项目总结/摘要 这个第一阶段项目的长期目标是将一种家用设备商业化， 在安全地坐着的同时进行锻炼，这可以使用户直观地参与， 通过任务、阅读或其他活动，可以显著减少久坐行为， 并显示具有从其他来源导出的生物特征的使用数据， 健康和远程监测健康状况的变化。通过这样做，我们预计将大幅提高 符合心脏康复计划规定的能量消耗水平。本申请要求 基金开发FitSitt，一个非常舒适的椅子，具有独特的动态座椅和背部支撑 主动响应、跟随和支持用户的运动，同时集成同步运动 用来锻炼腿的哑铃。这项技术的提出将改变久坐不动， 运动和锻炼，并可能有助于预防和改善心脏代谢健康的好处， 目标市场为美国近3100万65岁以上的非活跃成年人，并延长独立生活的年限。 虽然心脏康复被证明可以大大降低死亡率并提供重要的健康益处，但令人遗憾的是， 利用不足。久坐不动的行为与慢性病的急剧上升直接相关，但久坐不动的老年人 成年人不太可能保持锻炼习惯，因此FitSitt的方法是将一部分坐着的时间 从久坐到活动，分布在一天中，使运动体验轻松，因为它是 方便、易于使用、可用且舒适。初步研究表明， 当前Fitsitt 0.5的低电阻设置相当于步行1 mph。本研究的主要目的 该项目是完成先进的FitSitt 1.0原型的开发，扩展其功能以确保安全， 增加了技术价值和家庭使用可行性可能性。具体目标是：目标1a： 工程师/升级FitSitt 0.5的功能，以实现长时间的最佳家庭舒适性和舒适性。 目标1b：设计并校准算法，以收集来自车载传感器的使用统计数据。聚集， 与从单独的可穿戴设备导出的心率数据进行关联和校准。目标2：电子数据收集 和校准，并评估组合功能FitSitt 1.0的可用性。老年人谁经历了一个 在过去6个月内发生心脏事件的患者，在24- 小时，然后完成用户体验访谈和评级，包括修改后的系统可用性 规模第二阶段的计划包括进一步完善硬件和扩展软件功能， 商业化，并建造10个先进的原型，用于额外和扩展的用户测试， 在家进行为期数周的试验。该项目的最终目标是将以下内容的聚合联合收割机合并到一个平台中： 具有康复设备健康数据，该康复设备可以用于通过较少的久坐来作用于和改善数据 生活和增加身体活动分布在一天。

PROJECT SUMMARY/ABSTRACT The long term goal of this Phase I project is to commercialize an in-home device that facilitates significant levels of ongoing exercise while safely seated, that can enable intuitive engagement by the user, that doesn’t interfere with tasking, reading or other activities, that can significantly reduce sedentary behavior, and that can aggregate and display usage data with biometrics derived from other sources to present an actionable picture of one’s health and remote monitoring of changes in health status. By doing so, we expect to substantially raise compliance to prescribed levels of energy expenditure of a cardiac rehab program. This application requests funds to develop the FitSitt, a highly comfortable chair with a uniquely articulating dynamic seatand back support that actively respond to, follow, and support the user's movements while integrating a synchronously-moving treadle with which to exercise legs. The technology proposed will transform sitting from sedentariness to movement and exercise and may contribute preventive and ameliorative cardio-metabolic health benefits to a target market of nearly 31 million inactive adults aged 65+ in the US and prolong years of independent living. While cardiac rehab is proven to dramatically reduce mortality and provide important health benefits, it is woefully under-utilized. Sedentary behavior is directly linked to a dramatic rise in chronic disease, but sedentary older adults are not likely to maintain exercise habits, so the approach is for FitSitt to convert a portion of sitting time from sedentary to active, distributed across the day, enabling movement experienced as effortless because it is convenient, easy to use, available, and comfortable. Preliminary studies show that the energy expenditure at a low resistance setting for the current Fitsitt 0.5 is equivalent to walking 1 mph. The primary objective of this project is to complete development of an advanced FitSitt 1.0 prototype, expanding its features to assure safety, increase technical merit and likelihood of feasibility for home use. The specific Aims are: Aim 1a: Engineer/upgrade FitSitt 0.5’s features for optimal in-home maneuverabilityand comfort over extended periods. Aim 1b: Design, then calibrate algorithms to collect use statistics data from on-board sensors. Aggregate, correlate, and calibrate with heart rate data derived from a separate wearable. Aim 2: Validate data collection and calibration, and evaluate usability of combined-feature FitSitt 1.0. Older adults who have experienced a cardiac event within the past 6 months will have unstructured use of the chair in their own homes during a 24- hour period and then complete a user experience interview and rating including a modified System Usability Scale. Plans for Phase II include further refinement of hardware and expansion of software capabilities toward commercialization, and the construction of 10 advanced prototypes for additional and extended user testing over multi-week trials at home. The ultimate goal of this project is to combine into one platform the aggregation of health data with a rehabilitative device which can be used to act on and improve that data through less sedentary living and increased physical activity distributed across the day.
