Mobilize Center: Models for Mobile Sensing and Precision Rehabilitation

项目总结 动员中心是一个生物医学技术资源中心(BTRC)，其目标是 利用移动设备创建和传播量化运动生物力学的创新工具 技术，并提供个性化的移动健康康复计划。其中一个 Center的新工具是OpenCap，它使研究人员能够量化和分析 来自智能手机视频的三维人体运动的生物力学。这款免费的基于云的工具 于2022年7月上映。它已经被1500多名生物力学研究人员使用 并收集了40,000多项运动捕捉试验的数据。作为BTRC，动员 中心也有培训和传播目标，包括创建和维护 数据共享社区，以加快研究。数据共享在以下情况下尤其具有影响力 涉及深度学习应用程序，满足其对大型数据集的需求。OpenCap降低了 社区收集和处理运动数据的障碍，因此提出了一种 有机会同时推进动员中心的数据共享目标。然而， OpenCap的主要目的是收集数据，而不是共享数据。它缺少以下关键功能 开放数据共享和科学可再现性，例如关联元数据的机制， 搜索和过滤数据集以下载、将数据链接到出版物(S)、注册数据并提供 对数据的永久引用(例如，DOI)。而不是为这些重新发明轮子 我们将利用SimTK这一旨在促进开放科学的在线平台。SimTK 是一个基于Web的软件、模型和数据共享存储库，用于生物计算 拥有超过13万名成员的社区。具体地说，我们将使OpenCap可以与 SimTK方式：1)集成OpenCap和SimTK，支持全功能的视频和运动数据 共享，以便OpenCap数据集可以利用SimTK功能来促进开放 科学；2)扩展SimTK的API，使OpenCap能够收集标准化的元数据。 实现这些目标将扩大我们的数据共享目标的影响，使OpenCap 广泛使用，并增加了OpenCap的数量、多样性、可查找性和可重用性 数据集。

PROJECT SUMMARY The Mobilize Center is a Biomedical Technology Resource Center (BTRC) with the goals of creating and disseminating innovative tools to quantify movement biomechanics with mobile technologies and deliver personalized mobile health rehabilitation programs. One of the Center’s new tools is OpenCap, which enables researchers to quantify and analyze the biomechanics of 3-D human movement from smartphone videos. This free, cloud-based tool was released in July 2022. It is already in use by more than 1,500 biomechanics researchers and has compiled data from more than 40,000 motion capture trials. As a BTRC, the Mobilize Center also has training and dissemination aims, including an aim to create and maintain data-sharing communities to accelerate research. Data-sharing is particularly impactful when it comes to deep learning applications with their need for large datasets. OpenCap lowers the barrier for communities to collect and process motion data, and therefore, presents an opportunity to simultaneously advance the Mobilize Center’s data-sharing aim. However, OpenCap’s primary purpose is data collection and not data sharing. It lacks key features for open data sharing and scientific reproducibility, such as a mechanism to associate metadata, search and filter datasets to download, link data to publication(s), register the data, and provide a permanent reference (e.g., a DOI) to the data. Rather than reinventing the wheel for these features, we will leverage SimTK, an online platform designed to promote open science. SimTK is a web-based software, model, and data-sharing repository for the biocomputational community with over 130,000 members. Specifically, we will make OpenCap interoperable with SimTK by: 1) Integrating OpenCap and SimTK to support full-featured video and motion data sharing, so that OpenCap datasets can take advantage of SimTK functionality to promote open science, and 2) Extending SimTK’s API to enable OpenCap to collect standardized metadata. Achieving these aims will expand the impact of our data-sharing aim, make OpenCap more widely used, and increase the number, diversity, findability and re-usability of OpenCap’s datasets.
