DataGait: Gait as a Measure of Functional Mobility on Discharge

这个项目正在开发一个用户友好的应用程序，它可以用你自己的手机测量步行，这可以被社区的临床医生和患者使用，在出院和/或从COVID-19中恢复后，客观地测量他们的步行质量，这是一个关键的健康指标。我们正在了解COVID-19如何影响人们，但我们现在知道，对一些人来说，它可能是一个长期的疾病，恢复缓慢。“长期新冠肺炎”患者会出现一系列症状，包括疲劳、行走等体力活动时呼吸困难、心动过速、疼痛和神经痛。患有COVID-19或从COVID-19中恢复的患者采用步行方式，他们抑制能量消耗;这可以通过步态分析，通过客观测量间接的心肺功能和疲劳来检测。步行受身体生理功能的各种复杂相互作用的影响，可以提供有关个人健康和一般健康状况的深入信息。NHS的物理治疗师已经确定了需要一个系统来监测流动性，同时对呼吸困难进行更具体的个人评估，以指导他们在治疗这些患者时做出决策。我们提出了一种远程监测系统，该系统将允许终端用户通过捕获用于分析、报告并反馈给临床医生。该系统将通过标准化测试，包括10米和2分钟的步行，使用临床验证和接受的耐力和运动能力指标。通过使用现有的智能手机传感器对这些测试进行仪器化，它们将客观地提供具有临床价值和用途的时间（计时）和空间（距离和步行速度）步行结果。此外，我们的系统将为患者提供一种获取一系列其他措施的方法，以形成电子“恢复日志”。这些数据将与专家临床医生共享，从而获得客观和纵向的信息，以支持临床决策和对疑似、确诊或有风险的COVID-19患者进行风险评估。随着对前线NHS员工的需求不断增加，以及大多数非紧急门诊预约被推迟，物理治疗师特别要求开发和部署这样的应用程序。我们将与主要利益相关者，临床医生，最终用户以及世界知名学者合作，提供一个可以在项目开始后六个月内测试和部署的产品，并且其可以适用于其他现有的临床状况和复发的流行病和即将到来的大流行病。这项步态技术此前得到了InnovateUK ICURe 26（https：//icure.uk/）的支持，并与全球100名健康专业人士、组织和商业领袖进行了联系，以进行市场验证。

This project is developing a user friendly App, which measures walking using your own phone, which can be used by clinicians and patients in the community, following discharge and/or recovering from COVID-19, to objectively measure their walking-quality, a key health indicator.We are learning about how COVID-19 affects people, but we now know that for some people it can be a long term illness with a slow recovery. People with ‘long covid’ experience a range of symptoms including fatigue, breathlessness during physical activity such as walking, tachycardia, pain and neuralgia. Patients with or recovering from COVID-19 adopt a walking style where they curb energy expenditure; this can be detected by gait analysis, by objectively measuring indirect cardio-respiratory functioning and fatigue. Walking is influenced by various complex interactions of the body's physical functioning, and can provide in-depth information on wellbeing and the general health status of an individual. NHS physiotherapists have identified the need for a system to monitor mobility alongside more specific individual assessments of breathlessness to guide their decision making in the treatment of these patients.Currently, specific walking tests are used clinically in a subjective way; we propose a remote monitoring system that will allow end-users to monitor their own health status, by capturing objective data for analysis, reporting, and feedback to clinicians. The system will use clinically validated and accepted measures of endurance and movement ability, via standardised tests including 10 metre and 2-minute walks. By instrumenting these tests with existing smartphone sensors, they will be objective providing both temporal (timing) and spatial (distance and walking speed) walking outcomes which have clinical value and use. In addition, our system will offer patients a means to capture a range of other measures to form an electronic ‘recovery diary’.This data will be shared with expert clinician therefore obtaining objective and longitudinal information which would support clinical decision making and risk assessments for people with suspected, confirmed or at risk of COVID-19. With the demand on frontline NHS staff ever increasing, and with most non-urgent out-patient appointments postponed, physiotherapists have specifically requested an application like this to be developed and deployed.We will work with key stakeholders, clinicians, end-users as well as world-renowned academics, to deliver a product which can be tested and deployed within six months from project start, and which can be adapted for other existing clinical conditions and recurring epidemics and pandemics to come. This gait technology was previously supported by InnovateUK ICURe26 (https://icure.uk/) to market validate, with contacts made with 100 health professionals and organisations and business leaders around the world.
