The assessment of joint ranges is an essential component of the physical examination, enabling monitoring and follow-up. Additionally, it is a key component of muscle mobility assessment. Smartphone applications for range-of-motion assessments offer a cost-effective alternative to traditional measurement tools, reducing the need for expensive equipment while maintaining accuracy. Their portability and ease of use provide significant advantages in clinical settings, allowing for quicker assessments. This, in turn, can enhance patient care by enabling more frequent monitoring and timely interventions, ultimately improving treatment outcomes. This study evaluated the validity and reliability of the PhysioMaster application in measuring knee range of motion. Twenty-nine participants performed passive knee extensions, with data collected simultaneously through the application and video recordings for posterior angle calculations. The application demonstrated excellent validity, with intraclass correlation (ICC = between 0.729 and 0.814) and the Pearson correlation values ranging from r = 0.908 to 0.974. For inter-rater reliability, ICC was 0.898 and Pearson correlation coefficient r = 0.82. Additionally, the coefficient of variation was 5.18%, and the measurement error was 0.82°. The results showed that the PhysioMaster application is a valid and reliable tool for assessing passive knee extension in clinical environments, supporting efficient and accurate patient evaluations.
关节活动范围的评估是体格检查的重要组成部分，有助于进行监测和随访。此外，它也是肌肉活动度评估的关键组成部分。用于活动范围评估的智能手机应用程序提供了一种经济高效的替代传统测量工具的方法，在保持准确性的同时减少了对昂贵设备的需求。它们的便携性和易用性在临床环境中具有显著优势，能够进行更快的评估。这反过来可以通过更频繁的监测和及时的干预来加强患者护理，最终改善治疗效果。本研究评估了PhysioMaster应用程序在测量膝关节活动范围方面的有效性和可靠性。29名参与者进行了被动膝关节伸展，通过该应用程序和视频记录同时收集数据以计算后角。该应用程序显示出极佳的有效性，组内相关系数（ICC = 0.729至0.814之间）以及皮尔逊相关值范围从r = 0.908至0.974。对于评分者间可靠性，ICC为0.898，皮尔逊相关系数r = 0.82。此外，变异系数为5.18%，测量误差为0.82°。结果表明，PhysioMaster应用程序是临床环境中评估被动膝关节伸展的有效且可靠的工具，有助于进行高效准确的患者评估。
