Physical activity (PA), including regular exercise, is essential for the successful management of axial spondyloarthritis (axSpA). To promote a physically active lifestyle, a digital training diary (Trainingslog) was developed in an user-centered approach by the Swiss Ankylosing Spondylitis Association (SVMB). A training diary promotes PA through feedback, goal setting and self-monitoring, which can also be used for PA counselling by physiotherapists (PT). Usability, feasibility and acceptance are essential for the successful implementation of a mobile Health Intervention such as the Trainingslog. The study objective is to evaluate the usability, feasibility and acceptance of the Trainingslog for individuals with axSpA and PTs.
A mixed-methods design was performed among potential end-users of the Trainingslog. Quantitative data was collected by use of questionnaires (System Usability Scale (SUS, 0-100 scale), user version of the Mobile App Rating Scale (uMARS, 5 point scale)) and number of training entries. Subsequently, qualitative data was gathered through semi-structured online focus groups or individual interviews.
11 PTs (9 women, mean age 52.5 [SD 15.6]) and 10 individuals with axSpA (6 women, mean age 48 [SD 13.4]) participated. The quantitative data showed mean SUS scores for usability of 82.5 [SD 21.76] for PTs and 77.0 [SD 9.34] for individuals with axSpA. The mean uMARS sector B scores for feasibility were 4.2 [SD 0.49] for PTs and 4.1 [SD 0.38] for individuals with axSpA. Acceptance, as indicated by the uMARS results (mean score > 3 in Sectors E and F for both groups), was given. But there was a lower-than-expected agreement in the training entries, with 59.86% of entries matching between the Trainingslog and the paper diary. The qualitative analysis unveiled that while usability and feasibility were good, acceptance was lower, primarily due to the use of a web-based link instead of an app version.
The Trainingslog showed a good usability and feasibility, while the acceptance was lower than expected. Acceptance could be increased by offering the Trainingslog as an app-based version, along with implementing additional recommendations for enhancement. Consequently, the Trainingslog has the potential to be applied in PA counselling by PTs or as a self-monitoring tool for individuals with axSpA.
身体活动（PA），包括定期锻炼，对于成功管理轴性脊柱关节炎（axSpA）至关重要。为了促进积极的生活方式，瑞士强直性脊柱炎协会（SVMB）以用户为中心的方法开发了一个数字训练日记（Trainingslog）。训练日记通过反馈、目标设定和自我监测来促进身体活动，这也可被物理治疗师（PT）用于身体活动咨询。可用性、可行性和可接受性对于成功实施诸如Trainingslog这样的移动健康干预至关重要。本研究的目的是评估Trainingslog对axSpA患者和物理治疗师的可用性、可行性和可接受性。
在Trainingslog的潜在最终用户中进行了混合方法设计。通过问卷（系统可用性量表（SUS，0 - 100分制）、移动应用评分量表用户版（uMARS，5分制））和训练记录数量收集定量数据。随后，通过半结构化在线焦点小组或个人访谈收集定性数据。
11名物理治疗师（9名女性，平均年龄52.5岁[标准差15.6]）和10名axSpA患者（6名女性，平均年龄48岁[标准差13.4]）参与了研究。定量数据显示，物理治疗师的可用性SUS平均得分为82.5分[标准差21.76]，axSpA患者为77.0分[标准差9.34]。物理治疗师的可行性uMARS B部分平均得分为4.2分[标准差0.49]，axSpA患者为4.1分[标准差0.38]。uMARS结果表明两组均接受（E和F部分平均得分>3）。但训练记录中的一致性低于预期，Trainingslog与纸质日记之间的记录匹配率为59.86%。定性分析表明，虽然可用性和可行性良好，但接受度较低，主要原因是使用了基于网络的链接而非应用程序版本。
Trainingslog显示出良好的可用性和可行性，但接受度低于预期。通过提供基于应用程序的版本，并实施其他改进建议，可以提高接受度。因此，Trainingslog有潜力应用于物理治疗师的身体活动咨询或作为axSpA患者的自我监测工具。
