Abstract：
Digital therapeutics refers to smartphone applications, software, and wearable devices that provide digital solutions to improve healthcare delivery. We developed a digital platform to support the GYM (Grow Your Muscle) study, an ongoing 48-week randomized, controlled trial on reduction of sarcopenia through a home-based, app-monitored physical exercise intervention. The GYM platform consists of a smartphone application including the exercise program and video tutorials of body-weight exercises, a wearable device to monitor heart rate during training, and a website for downloading training data to remotely monitor the exercise. The aim of this paper is to describe the platform in detail and to discuss the technical issues emerging during the study and those related to usability of the smartphone application through a retrospective survey. The main technical issue concerned the API level 33 upgrade, which did not enable participants using the Android operating systems to use the wearable device. The survey revealed some problems with viewing the video tutorials and with internet or smartphone connection. On the other hand, the smartphone application was reported to be easy to use and helpful to guide home exercising. Despite the issues encountered during the study, this digital-supported physical exercise intervention could provide useful to improve muscle measures of sarcopenia.
摘要：
数字疗法指的是智能手机应用，软件,和可穿戴设备，提供数字解决方案，以改善医疗保健服务。我们开发了一个数字平台来支持GYM（增长你的肌肉）研究，正在进行的48周随机，通过家庭减少肌少症的对照试验，应用监控的体育锻炼干预。GYM平台由智能手机应用程序组成，包括锻炼程序和体重锻炼的视频教程，在训练期间监测心率的可穿戴设备，以及用于下载训练数据以远程监控演习的网站。本文的目的是详细描述平台，并通过回顾性调查讨论研究过程中出现的技术问题以及与智能手机应用程序可用性相关的技术问题。主要技术问题涉及API33级升级，这使得使用Android操作系统的参与者无法使用可穿戴设备。调查显示，观看视频教程以及互联网或智能手机连接存在一些问题。另一方面,据报道，智能手机应用程序易于使用，有助于指导家庭锻炼。尽管在研究过程中遇到了一些问题，这种数字支持的体育锻炼干预措施可以改善肌肉肌肉减少症的测量。
