OBJECTIVE: This study aims to improve the design and technology of YogiTherapy and evaluate its usability and quality.
METHODS: We newly implemented the mobile eHealth app YogiTherapy with a modern design, the option to change language, and easy navigation to improve the app\'s usability and quality for patients. After refinement, we evaluated the app by conducting a study with 16 patients with AS (4 female and 12 male; mean age 48.1, SD 16.8 y). We assessed the usability of YogiTherapy with a task performance test (TPT) with a think-aloud protocol and the quality with the German version of the Mobile App Rating Scale (MARS).
RESULTS: In the TPT, the participants had to solve 6 tasks that should be performed on the app. The overall task completion rate in the TPT was high (84/96, 88% completed tasks). Filtering for videos and navigating to perform an assessment test caused the largest issues during the TPT, while registering in the app and watching a yoga video were highly intuitive. Additionally, 12 (75%) of the 16 participants completed the German version of MARS. The quality of YogiTherapy was rated with an average MARS score of 3.79 (SD 0.51) from a maximum score of 5. Furthermore, results from the MARS questionnaire demonstrated a positive evaluation regarding functionality and aesthetics.
CONCLUSIONS: The refined and tested YogiTherapy app showed promising results among most participants. In the future, the app could serve its function as a complementary treatment for patients with AS. For this purpose, surveys with a larger number of patients should still be conducted. As a substantial advancement, we made the app free and openly available on the iOS App and Google Play stores.
目的:本研究旨在改进YogiTherapy的设计和技术,并评估其可用性和质量。
方法:我们以现代设计新实施了移动eHealth应用程序YogiTherapy,更改语言的选项,和轻松导航,以提高应用程序的可用性和质量为患者。细化后,我们通过对16例AS患者(4例女性,12例男性;平均年龄48.1,SD16.8岁)进行研究,对应用进行了评估.我们通过具有思考协议的任务性能测试(TPT)和德语版移动应用程序评定量表(MARS)评估了YogiTherapy的可用性。
结果:在TPT中,参与者必须解决应该在应用程序上执行的6个任务。TPT中的整体任务完成率较高(84/96,88%完成任务)。过滤视频并导航以执行评估测试在TPT期间导致了最大的问题,在应用程序中注册和观看瑜伽视频时非常直观。此外,16名参与者中有12名(75%)完成了德语版的MARS。YogiTherapy的质量从最高得分为5,平均MARS得分为3.79(SD0.51)。此外,MARS问卷的结果显示,对功能性和美观性的评价是积极的.
结论:经过完善和测试的YogiTherapy应用程序在大多数参与者中显示了有希望的结果。在未来,该应用程序可以作为AS患者的补充治疗。为此,仍需对更多患者进行调查.作为一个实质性的进步,我们使应用程序免费和开放的iOS应用程序和谷歌播放商店。
