背景:除了抗炎药,体育锻炼是轴性脊柱关节炎(AS)患者现代治疗的基石。数字健康应用程序(DHAs),如瑜伽应用程序YogiTherapy可以远程授权患者自主和正确地进行锻炼。
目的:本研究旨在设计和开发基于智能手机的应用程序,YogiTherapy,对于AS患者。为了获得对图形用户界面(GUI)可用性的更多见解,以进一步开发应用程序,这项研究专注于评估用户与GUI的交互。
方法:应用程序的开发和用户体验研究发生在2020年10月至2021年3月之间。DHA是由工程专业的学生设计的,风湿病学家,和AS患者。经过最初的开发过程,该应用程序的试点版本由5名患者和5名风湿病学家进行了评估。参与者必须与应用程序的GUI进行交互,并在应用程序中完成5个导航任务。随后,完成率和经验问卷(吸引力,perspecuity,效率,可靠性,刺激,和新颖性)由患者完成。
结果:后测问卷的结果显示,大多数患者已经熟悉数字应用程序(4/5,80%)。任务T1和T2的可用性测试的任务完成率为100%(5/5),其中包括选择和开始瑜伽课程并导航到信息页面。风湿病学家表示,他们甚至更有经验的数字设备(2/5,40%的专家;3/5,60%的中间体)。在这种情况下,他们对所有5个可用性任务T1至T5的任务完成率为100%(5/5)。用户体验问卷的平均结果范围从-3(最负面)到+3(最正面)。根据风湿病学家的评估,与可靠性(平均2.000,SD0.395)相比,吸引力(平均2.267,SD0.401)和刺激(平均2.250,SD0.354)取得了最好的平均结果。患者的吸引力平均为2.167(SD0.565),刺激平均为1.950(SD0.873)。最低的平均得分是关于洞察力的报告(平均1.250,SD1.425)。
结论:新开发和测试的DHAYogiTherapy在风湿病学家和风湿性疾病患者中表现出中等可用性。该应用程序可用于AS患者作为补充治疗。GUI的初始评估确定了在开始临床评估之前需要解决的重要可用性问题。在第二步中还需要进行前瞻性试验,以证明该应用程序的临床益处。
BACKGROUND: Besides anti-inflammatory medication, physical exercise represents a cornerstone of modern treatment for patients with axial spondyloarthritis (AS). Digital health apps (DHAs) such as the yoga app YogiTherapy could remotely empower patients to autonomously and correctly perform exercises.
OBJECTIVE: This
study aimed to design and develop a smartphone-based app, YogiTherapy, for patients with AS. To gain additional insights into the usability of the graphical user interface (GUI) for further development of the app, this
study focused exclusively on evaluating users\' interaction with the GUI.
METHODS: The development of the app and the user experience
study took place between October 2020 and March 2021. The DHA was designed by engineering students, rheumatologists, and patients with AS. After the initial development process, a pilot version of the app was evaluated by 5 patients and 5 rheumatologists. The participants had to interact with the app\'s GUI and complete 5 navigation tasks within the app. Subsequently, the completion rate and experience questionnaire (attractiveness, perspicuity, efficiency, dependability, stimulation, and novelty) were completed by the patients.
RESULTS: The results of the posttest questionnaires showed that most patients were already familiar with digital apps (4/5, 80%). The task completion rates of the usability test were 100% (5/5) for the tasks T1 and T2, which included selecting and starting a yoga lesson and navigating to an information page. Rheumatologists indicated that they were even more experienced with digital devices (2/5, 40% experts; 3/5, 60% intermediates). In this case, they scored task completion rates of 100% (5/5) for all 5 usability tasks T1 to T5. The mean results from the User Experience Questionnaire range from -3 (most negative) to +3 (most positive). According to rheumatologists\' evaluations, attractiveness (mean 2.267, SD 0.401) and stimulation (mean 2.250, SD 0.354) achieved the best mean results compared with dependability (mean 2.000, SD 0.395). Patients rated attractiveness at a mean of 2.167 (SD 0.565) and stimulation at a mean of 1.950 (SD 0.873). The lowest mean score was reported for perspicuity (mean 1.250, SD 1.425).
CONCLUSIONS: The newly developed and tested DHA YogiTherapy demonstrated moderate usability among rheumatologists and patients with rheumatic diseases. The app can be used by patients with AS as a complementary treatment. The initial evaluation of the GUI identified significant usability problems that need to be addressed before the start of a clinical evaluation. Prospective trials are also needed in the second step to prove the clinical benefits of the app.
