背景技术背景：肢体残疾人（PWD）面临着一些独特的挑战，使他们无法参加现场锻炼计划。虽然移动的应用程序可以提供一个无处不在的渠道，在社区内提供方便的运动服务，没有运动应用程序已被设计为残疾人谁经历某些功能limited.Objective：本研究的目的是检查的可用性的移动的运动应用程序在PWD.METHODS：一个顺序的解释性混合方法的设计被用来全面测试可用性的4个核心领域：有效性（即易用性）、效率（即操作速度）、感知满意度和有用性。参与者完成了7个面对面的可用性任务和1个结构化面试。设备包括一台预装了锻炼应用程序的平板电脑。该应用程序包括锻炼视频，重点关注健身的几个组成部分：有氧能力，肌肉力量，功能性力量或平衡，以及运动范围。该应用程序包含3种不同版本的锻炼计划：（1）适用于能够使用上肢和下肢的人的计划，（2）适用于仅能够使用上肢的人的坐姿计划，以及（3）专为偏瘫患者设计的计划。该应用程序还包括信息图表形式的教育资源，旨在解决关键的社会认知理论结构，包括社会支持，结果预期，自我效能，以及锻炼的障碍或促进因素。描述性报告了参与者特征和定量可用性数据。结果：共有12名PWD测试了锻炼应用程序的可用性，并在第一次尝试时完成了96%（69/72）的可用性任务。用户的操作速度各不相同，这促使开发团队对应用程序进行了微小的修改。定性结果显示了3个主要主题：促进运动采用，视频的积极体验，以及易于学习。参与者指出，该应用程序规避了与离开家（例如，恶劣的天气条件，健康状况或残疾症状恶化，交通困难，社会支持）相关的几个障碍：移动的运动应用程序提供了一个简单的平台，是有效的，有用的，并赞赏残疾人。参与者还认为该应用程序易于使用，并认为它是帮助残疾人获得定期锻炼的宝贵工具。研究结果还提供了对参与者对移动的锻炼应用程序的偏好的深入了解，这些应用程序可以帮助未来的研究和开发项目。未来的运动试验需要确定移动的应用程序技术对残疾人生活方式身体活动的真正影响。试验注册：Clinicaltrials.gov NCT 03024320; https://clinicaltrials.gov/ct2/show/NCT03024320（由WebCite存档，网址为http：//www.webcitation.org/75hNLgRFH）。
BACKGROUND: People with physical disabilities (PWD) experience several unique challenges that prevent them from participating in onsite exercise programs. Although mobile apps can provide a ubiquitous channel for delivering convenient exercise services within the community, no exercise apps have been designed for people with disabilities who experience certain functional limitations.OBJECTIVE: The aim of this study was to examine the usability of a mobile exercise app in PWD.METHODS: A sequential explanatory mixed-method design was used to holistically test usability in 4 core areas: effectiveness (ie, ease of use), efficiency (ie, operation speed), perceived satisfaction, and usefulness. Participants completed 7 face-to-face usability tasks and 1 structured interview. Equipment included a computer tablet that came preinstalled with the exercise app. The app included exercise videos that focused on several components of fitness: aerobic capacity, muscular strength, functional strength or balance, and range of motion. The app contained 3 different versions of the exercise program: (1) a program for people with the ability to use the upper and lower limbs, (2) a seated program for people with the ability to use only upper limbs, and (3) a program designed for people with hemiparesis. The app also included educational resources in the form of infographics aimed at addressing key social cognitive theory constructs included social support, outcome expectancies, self-efficacy, and barriers or facilitators to exercising. Participant characteristics and quantitative usability data were descriptively reported. Qualitative data were analyzed using thematic analysis.RESULTS: A total of 12 PWD tested the usability of the exercise app and completed 96% (69/72) of the usability tasks on the first attempt. Operation speed varied among users, which prompted the development team to make minor revisions to the app. Qualitative results demonstrated 3 overarching themes: facilitates exercise adoption, positive experiences of videos, and easy to learn. Participants noted that the app circumvented several barriers to exercise associated with leaving the home (eg, inclement weather conditions, exacerbations of health conditions or disability symptoms, difficulties with transportation, and social support).CONCLUSIONS: The mobile exercise app provided a simple platform that was effective, useful, and appreciated by PWD. Participants also perceived the app as easy to use and felt it was a valuable tool for assisting PWD to obtain regular exercise. Study findings also offered insight into the participants' preferences for mobile exercise apps that can aid future research and development projects. Future exercise trials are needed to determine the true impact of mobile app technology on lifestyle physical activity in people with disabilities.TRIAL REGISTRATION: Clinicaltrials.gov NCT03024320; https://clinicaltrials.gov/ct2/show/NCT03024320 (Archived by WebCite at http://www.webcitation.org/75hNLgRFH).
