Project Summary The overall goal of the proposed work is to develop a platform capable of delivering and monitoring adherence, proficiency, and safety of a home-based simplified Tai Chi intervention for older adults. During Phase I of this Fast-Track STTR project we will further develop a novel approach to assessing Tai Chi performance adherence, proficiency, and safety based on wearable sensor data. Metrics of adherence and safety will be determined. A multi-item proficiency scoring metric will be developed using a modified Delphi consensus process. Subjects will be asked to perform movements in the laboratory from the simplified Tai Chi intervention while wearing a network of nine-axis sensors. Proficiency will be assessed by Tai Chi experts using the previously developed metric. Collected data will be used to aid development of algorithms to predict adherence, proficiency, and safety. Sensitivity analyses will be performed to identify the minimum number of sensors necessary to achieve satisfactory results. During Phase I we will also carry out stakeholder focus groups to inform the development of a user-friendly Tele-Tai Chi platform. During Phase II of this Fast-Track STTR project we will develop a user-friendly ‘Tele-Tai Chi’ platform via a user-centered design approach. To accomplish this aim, we will develop a platform consisting of a wireless body sensor network, a tablet computer (to collect data, and provide instructions and feedback), and a web- based dashboard (for remote access to program data). An iterative design approach will be employed based on the needs of the end-user including practitioners, Tai Chi instructors, and researchers. Focus groups will be employed to ascertain this information over the course of the project. Next we will demonstrate feasibility of tracking adherence, proficiency and safety over a 3-month training period in a 3 consecutive cohorts (n=10 each) of older adults. For this preliminary test of our platform, subjects will participate in a 12-week home-based simplified Tai Chi program delivered via pre-programed tablets, supplemented with laboratory visits at baseline, 3, 6, and 12 weeks. Subjects will be asked to practice at home for 45 minutes a minimum of 3 times per week. Instumented laboratory visits will: a) simulate typical home practice sessions and provide additonal data on usability and inform estimates of adherence and proficiency algorithms; and b) allow for longitudinal evaluation of function and postural control, which will be used to explore associations between platform-derived measures of adherence and proficiency and fall risk.

项目摘要 拟议工作的总体目标是开发一个能够提供和监测遵守情况的平台， 熟练程度和安全性的家庭为基础的简化太极干预老年人。 在这个快速通道STTR项目的第一阶段，我们将进一步开发一种评估Tai的新方法 基于可穿戴传感器数据的Chi性能依从性、熟练度和安全性。度量 将确定依从性和安全性。多项目熟练度评分指标将使用 改良德尔菲共识法。将要求受试者在实验室中从 佩戴九轴传感器网络时简化了太极拳干预。熟练程度将通过以下方式进行评估： 太极专家使用以前开发的度量。收集的数据将用于帮助开发 预测依从性、熟练度和安全性的算法。将进行敏感性分析，以确定 需要最少的传感器数量来获得满意的结果。在第一阶段，我们还将开展 与利益相关者焦点小组合作，为用户友好的远程太极平台的开发提供信息。 在这个快速通道STTR项目的第二阶段，我们将开发一个用户友好的“远程太极”平台， 以用户为中心的设计方法。为了实现这一目标，我们将开发一个由无线 身体传感器网络，平板电脑（收集数据，并提供指令和反馈），以及网络， 基于仪表板（用于远程访问程序数据）。将采用迭代设计方法， 根据最终用户的需求，包括从业人员，太极教练和研究人员。焦点小组将 在整个项目过程中，他们被用来确定这些信息。接下来，我们将展示 在3个连续队列中跟踪3个月培训期间的依从性、熟练度和安全性 （n=10）老年人。对于我们平台的初步测试，受试者将参加为期12周的 以家庭为基础的简化太极计划通过预先编程的平板电脑提供，并辅以实验室 基线、第3、6和12周访视。受试者将被要求在家练习至少45分钟， 每周3次。实验室检查将：a）模拟典型的家庭实践课程，并提供 关于可用性的附加数据，并告知依从性和熟练度算法的估计;以及B）考虑到 功能和姿势控制的纵向评价，将用于探索 平台衍生的依从性和熟练度以及跌倒风险的测量。
