There are numerous radiography and photogrammetry-based methods of assessing the cervical spine posture in the sagittal plane. The choice of instrument should be based on scientific parameters such as validity and reliability, thus avoiding restrictions to the applicability of the instrument.
What radiography and photogrammetry-based methods used to assess the cervical spine posture in the sagittal plane are valid and/or reliable?
Systematic searches were conducted following Meta-analysis of Observational Studies in Epidemiology guidelines. Methodological quality was assessed according to the Brink & Louw appraisal tool.
Twenty-one studies were included in the qualitative analysis. Twenty different methods of calculating cervical spine posture in the sagittal plane were found. Two studies included validation measures, 16 studies assessed inter-rater reliability, and 17 studies assessed intra-rater reliability. Fourteen studies were included for the quantitative analysis. The meta-analysis shows that the cervical arrow and cervical lordosis photogrammetry-based methods present very high intra-rater reliability. In radiography, the meta-analysis also showed that the Cobb method (inferior C2 - inferior C7), Cobb method (middle C1 - inferior C7), absolute rotation angle, and Gore angle (C2-C7) present very high inter-rater reliability, and the Cobb method (inferior C2 - inferior C7) and absolute rotation angle present very high intra-rater reliability.
This systematic review presents an overview of the methods used to assess cervical spine posture and the respective information on validity and reliability. This panorama facilitates the choice of method when conducting radiography or photogrammetry-based assessment of the cervical spine in the sagittal plane. In addition, it shows the need for new studies that investigate the accuracy and precision of these methods for their possible use in larger studies.
有许多基于影像学和摄影测量学的方法可用于评估颈椎矢状位姿势。仪器的选择应基于有效性和可靠性等科学参数，从而避免对仪器适用性的限制。
用于评估颈椎矢状位姿势的基于影像学和摄影测量学的方法有哪些是有效的和/或可靠的？
根据观察性研究荟萃分析的循证医学指南进行系统检索。根据 Brink 和 Louw 评估工具评估方法学质量。
21 项研究纳入定性分析。发现了 20 种不同的计算颈椎矢状位姿势的方法。两项研究纳入了验证性措施，16 项研究评估了组内信度，17 项研究评估了组内信度。有 14 项研究纳入定量分析。荟萃分析表明，颈椎箭头和颈椎前凸摄影测量法具有非常高的组内信度。在影像学方面，荟萃分析还表明 Cobb 法（下颈椎 2 至下颈椎 7）、Cobb 法（颈椎 1 中点至下颈椎 7）、绝对旋转角度和 Gore 角（C2-C7）具有非常高的组间信度，而 Cobb 法（下颈椎 2 至下颈椎 7）和绝对旋转角度具有非常高的组内信度。
本系统综述介绍了评估颈椎姿势的方法以及各自的有效性和可靠性信息。该全景图有助于在进行颈椎矢状位的影像学或摄影测量评估时选择方法。此外，它还表明需要开展新的研究，以调查这些方法的准确性和精密度，以便在更大规模的研究中可能使用。
