FitMi Plus: Smart Functional Modules for Practicing Activities of Daily Living after Stroke

每年有70万人在中风中幸存下来，其中超过50%的人有持续性运动 减损。密集康复可以减少他们的损伤，但获得这种治疗是 有限的。家庭治疗可以补充治疗师的时间，但目前的护理标准是 简单地向个人提供打印的练习表，这是一种没有动力和 通常都是无效的。确实存在技术解决方案，但没有一个提供有效的手段 个人在家中以激励性的方式直接练习日常生活活动。这个 此Fast Track SBIR的目标是开发和测试FitMi Plus，FitMi Plus是Flint Rehab的改进版本 商业上成功的FitMi系统，用于激励家庭治疗锻炼。原版 FitMi系统由两个名为PUCK的无线输入设备组成，每个设备都包含 传感器并连接到一个软件应用程序，该应用程序可以检测到简单练习何时完成。 FitMi Plus将扩展FitMi的能力，通过以下方式检测日常生活活动的完成情况 通过不同的功能模块将公共对象耦合到PUK。这种方法有一个关键 允许重复使用系统中最昂贵和最复杂的组件的优势 每个功能模块，从而最大限度地降低成本和最大限度地提高系统灵活性。我们 假设FitMi Plus家庭治疗对运动障碍患者是可行的 由于中风和比现行标准更激励和有效的做法，印制 练习单。此Fast Track项目的目标是：1)建立FitMi的可行性 此外，通过试点测试可以检测门把手转动的初始4个功能模块， 拉上拉链，打开电灯开关，把液体倒进玻璃杯里；2)扩大图书馆 基于来自PTS和OTS的反馈的功能模块；以及3)比较家庭- 基于FitMi Plus的功能训练与非功能训练的随机对照试验 与慢性中风患者的关系。我们假设，使用FitMi Plus锻炼的人 在功能能力上的提高要比那些没有表现出来的人要大得多 在他们的家庭治疗中进行功能锻炼。如果成功，这个项目将导致 商业化的、经过临床验证的家庭治疗工具，可在 实际操作，从而提高中风后的远期功能恢复。

Over 50% of the 700,000 individuals who survive a stroke each year have persistent movement impairments. Intensive rehabilitation could reduce their impairments, but access to such therapy is limited. Home therapy could supplement time with a therapist, but the current standard of care is simply providing individuals printed sheets of exercises, an approach that is not motivating and often not effective. Technological solutions do exist, but none provide an effective means for individuals to directly practice activities of daily living in a motivating way on their own at home. The goal of this Fast Track SBIR is to develop and test FitMi Plus, an improved version of Flint Rehab’s commercially successful FitMi system for motivating at-home therapeutic exercise. The original FitMi system consists of two wireless input devices called Pucks that each contain an array of sensors and connect to a software application that detects when simple exercises are completed. FitMi Plus will expand the capabilities of FitMi to detect the completion of activities of daily living by coupling common objects to the Pucks via distinct Functional Modules. This approach has the key advantage of allowing the most expensive and complex components of the system to be reused with each Functional Module, thus minimizing cost and maximizing system flexibility. We hypothesize that home therapy with FitMi Plus will be feasible for individuals with motor impairment due to stroke and more motivating and effective than the current standard of practice, printed sheets of exercises. The aims of this Fast Track project are to: 1) Establish the feasibility of FitMi Plus by pilot testing an initial set of 4 Functional Modules that can detect turning a doorknob, zipping a zipper, turning on a light switch, and pouring liquid into a glass; 2) Expand the library of Functional Modules based on feedback from PTs and OTs; and 3) Compare the efficacy of home- based functional training with FitMi Plus to non-functional exercise in a randomized controlled trial with individuals with chronic stroke. We hypothesize that individuals who exercise with FitMi Plus will have significantly greater increases in functional ability than individuals who do not perform functional exercises during their home therapy. If successful, this project will result in a commercially-ready, clinically validated home therapy tool that could become widely adopted in actual practice, thus improving long-term functional recovery after stroke.
