Assessing shoulder joint range-of-motion (ROM) is crucial for evaluating shoulder mobility but remains challenging due to its complexity. This review examined the potential of single-camera markerless motion capture systems with an RGB-depth (RGB-D) sensor for shoulder ROM measurements, focusing on their reliability and validity.
We systematically searched nine databases through December 2022 for studies that evaluated the reliability and validity of single-camera markerless motion-capture systems in measuring simple (one-directional) and complex (multi-directional) shoulder movements. We extracted data on participant characteristics, device details, and measurement outcomes, and then assessed the methodological quality using the Consensus-Based Standards for the Selection of Health.
Of the 2,976 articles identified, 14 were included in this review. The findings indicate that intra-rater reliability findings across six studies were inconsistent, with simple movements like abduction and flexion demonstrating better reliability and less heterogeneity compared to complex movements. Validity assessments across 12 studies also showed inconsistency, with abduction and flexion measurements exhibiting higher validity than rotational movements. Studies focusing on simple movements reported good to excellent validity, particularly for abduction and flexion. Quality assessments using the COSMIN checklist revealed that the methodological quality varied across studies, ranging from inadequate to very good.
This systematic review suggests that RGB-D sensors show promise for measuring shoulder joint ROM, especially in simple movements like flexion and abduction. However, complex movements and inconsistencies limit their immediate clinical applicability, necessitating further high-quality research with advanced devices to ensure accurate and reliable assessments.
评估肩关节活动范围（ROM）对于评估肩部活动能力至关重要，但由于其复杂性，仍然具有挑战性。本综述研究了带有RGB深度（RGB-D）传感器的单相机无标记运动捕捉系统在测量肩部ROM方面的潜力，重点关注其可靠性和有效性。
我们系统地检索了截至2022年12月的九个数据库，以寻找评估单相机无标记运动捕捉系统在测量简单（单向）和复杂（多向）肩部运动时的可靠性和有效性的研究。我们提取了关于参与者特征、设备细节和测量结果的数据，然后使用基于共识的健康选择标准评估方法质量。
在识别出的2976篇文章中，有14篇被纳入本综述。研究结果表明，六项研究中的评分者内可靠性结果不一致，与复杂运动相比，外展和屈曲等简单运动显示出更好的可靠性和更少的异质性。12项研究的有效性评估也显示出不一致，外展和屈曲测量的有效性高于旋转运动。关注简单运动的研究报告了良好到优秀的有效性，特别是在外展和屈曲方面。使用COSMIN检查表进行的质量评估表明，不同研究的方法质量各不相同，从不足到非常好。
本系统综述表明，RGB-D传感器在测量肩关节ROM方面具有潜力，特别是在屈曲和外展等简单运动中。然而，复杂运动和不一致性限制了它们的直接临床适用性，需要使用先进设备进行进一步的高质量研究，以确保准确可靠的评估。
