BACKGROUND: Accuracy studies of biophotogrammetry protocols require standardization similar to radiography. OBJECTIVE: To estimate the diagnostic accuracy of a biophotogrammetric assessment protocol for cervical hyperlordosis, compared to radiography, and its intra- and inter-examiner reliability for measuring the cervical lordosis angle. METHODS: A study of diagnostic accuracy in women complaining of cervical pain. Two photos were taken using the CorelDraw biophotogrammetric protocol and one radiograph using the Cobb C1-C7 method. The Intra- and Inter-examiner reliability was calculated using the Kappa index and the intraclass correlation coefficient (ICC). The Bland-Altman plot and the ROC curve were presented. RESULTS: The sample consisted of 19 women. The accuracy of biophotogrammetry was 94.73% and the reliability between biophotogrammetry and radiography presented an ICC of 0.84 and a Kappa of 0.87. The excellent intra (ICC = 0.94) and inter-examiner (ICC = 0.86) reliability of the biophotogrammetry was confirmed. The area under the ROC curve was 93.5%. The Bland-Altman plot indicated differences between the two instruments close to the mean (1.5∘). CONCLUSION: The biophotogrammetric protocol proved to be accurate in diagnosing cervical hyperlordosis, with excellent reliability between the biophotogrammetric and radiographic assessments. It also demonstrated excellent intra- and inter-examiner reliability in measuring the cervical lordosis angle.

计算机生物摄影测量法诊断颈椎变化的准确性及其对颈椎前凸角的可靠性

背景：生物摄影测量协议的准确性研究需要类似于射线照相的标准化。目的：与 X 线照相相比，评估生物摄影测量评估方案对颈椎前凸的诊断准确性，以及测量颈椎前凸角度的检查者内部和检查者之间的可靠性。方法：对主诉颈椎疼痛的女性进行诊断准确性的研究。使用 CorelDraw 生物摄影测量协议拍摄了两张照片，使用 Cobb C1-C7 方法拍摄了一张射线照片。使用 Kappa 指数和组内相关系数 (ICC) 计算考官内部和考官间的可靠性。呈现了 Bland-Altman 图和 ROC 曲线。结果：样本由 19 名女性组成。生物摄影测量的准确度为 94。73%，生物摄影测量法和射线照相术之间的可靠性呈现 0.84 的 ICC 和 0.87 的 Kappa。确认了生物摄影测量法出色的内部 (ICC = 0.94) 和考官间 (ICC = 0.86) 可靠性。ROC曲线下面积为93.5%。Bland-Altman 图表明两种仪器之间的差异接近平均值 (1.5∘)。结论：生物摄影测量方案在诊断颈椎前凸过度症方面被证明是准确的，生物摄影测量和射线照相评估之间具有出色的可靠性。它还在测量颈椎前凸角方面表现出出色的检查者内部和检查者间可靠性。ROC曲线下面积为93.5%。Bland-Altman 图表明两种仪器之间的差异接近平均值 (1.5∘)。结论：生物摄影测量方案在诊断颈椎前凸过度症方面被证明是准确的，生物摄影测量和射线照相评估之间具有出色的可靠性。它还在测量颈椎前凸角方面表现出出色的检查者内部和检查者间可靠性。ROC曲线下面积为93.5%。Bland-Altman 图表明两种仪器之间的差异接近平均值 (1.5∘)。结论：生物摄影测量方案在诊断颈椎前凸过度症方面被证明是准确的，生物摄影测量和射线照相评估之间具有出色的可靠性。它还在测量颈椎前凸角方面表现出出色的检查者内部和检查者间可靠性。
