Accurate range of motion (ROM) assessment is essential for evaluating musculoskeletal function and guiding rehabilitation, particularly in pediatric populations. Traditional methods, such as optical motion capture and handheld goniometry, are often limited by cost, accessibility, and inter-rater variability. This study evaluated the feasibility and accuracy of the Microsoft Azure Kinect-powered Monitored Augmented Rehabilitation System (MARS) compared to Kinovea. Sixty-five pediatric participants (ages 5-18) performed standardized shoulder and elbow movements in the frontal and sagittal planes. ROM data were recorded using MARS and compared to Kinovea. Measurement reliability was evaluated using intraclass correlation coefficients (ICC3k), and accuracy was evaluated using root mean squared error (RMSE) analysis. MARS demonstrated excellent reliability with an average ICC3k of 0.993 and met the predefined accuracy threshold (RMSE ≤ 8°) for most movements, with the exception of sagittal elbow flexion. These findings suggest that MARS is a reliable, accurate, and cost-effective alternative for clinical ROM assessment, offering a markerless solution that enhances measurement precision and accessibility in pediatric rehabilitation. Future studies should enhance accuracy in sagittal plane movements and further validate MARS against gold-standard systems.
准确的活动范围（ROM）评估对于评估肌肉骨骼功能和指导康复至关重要，尤其是在儿科人群中。传统方法，如光学动作捕捉和手持式角度测量法，常常受到成本、可及性和评估者间差异的限制。本研究评估了由微软Azure Kinect驱动的监测增强康复系统（MARS）与Kinovea相比的可行性和准确性。65名儿科参与者（年龄5 - 18岁）在额面和矢状面进行了标准化的肩部和肘部运动。使用MARS记录ROM数据，并与Kinovea进行比较。使用组内相关系数（ICC3k）评估测量可靠性，使用均方根误差（RMSE）分析评估准确性。MARS表现出出色的可靠性，平均ICC3k为0.993，并且除矢状面肘部屈曲外，大多数运动均达到了预定义的准确性阈值（RMSE≤8°）。这些发现表明，MARS是临床ROM评估的一种可靠、准确且经济高效的替代方法，提供了一种无标记解决方案，提高了儿科康复中的测量精度和可及性。未来的研究应提高矢状面运动的准确性，并进一步将MARS与金标准系统进行验证。
