The objective of this study was to conduct the first patient usability testing of a mobile health (mHealth) system for in-home swallowing therapy. Five participants with a history of head and neck cancer evaluated the mHealth system. After completing an in-application (app) tutorial with the clinician, participants were asked to independently complete five tasks: pair the device to the smartphone, place the device correctly, exercise, interpret progress displays, and close the system. Quantitative and qualitative methods were used to evaluate the effectiveness, efficiency, and satisfaction with the system. Critical changes to the app were found in three of the tasks, resulting in recommendations for the next iteration. These issues were related to ease of Bluetooth pairing, placement of device, and interpretation of statistics. Usability testing with patients identified issues that were essential to address prior to implementing the mHealth system in subsequent clinical trials. Of the usability methods used, video observation (synced screen capture with videoed gestures) revealed the most information.
本研究旨在对一种用于居家吞咽治疗的移动医疗（mHealth）系统进行首次患者可用性测试。五名有头颈部癌症病史的参与者评估了 mHealth 系统。在完成了与临床医生的应用内（app）教程后，参与者被要求独立完成五项任务：将设备与智能手机配对、正确放置设备、锻炼、解释进展显示和关闭系统。使用定量和定性方法评估了系统的有效性、效率和满意度。在三个任务中发现了应用程序的关键更改，这为下一个迭代提出了建议。这些问题与蓝牙配对的便利性、设备的放置和统计数据的解释有关。对患者进行的可用性测试确定了在将 mHealth 系统应用于后续临床试验之前必须解决的问题。在使用的可用性方法中，视频观察（带视频记录手势的同步屏幕捕获）提供了最多的信息。
