We provide a meta-analysis for clinicians and researchers regarding reliability and validity of rasterstereographic measurement of the spinal posture.
A comprehensive PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) literature search identified 19 eligible studies evaluating reliability and validity of static rasterstereographic measurements in healthy subjects and patients with different spinal pathologies.
Our meta-analysis suggests that rasterstereography is a reliable and valid instrument to assess spinal posture parameters, especially thoracic kyphosis, lumbar lordosis, and scoliosis, reliability overall effect sizes rs > .91, ps < .001, validity overall effect sizes rs > 70, ps < .001, when compared to traditional radiological imaging techniques. Validity is higher in scoliosis patients compared with healthy controls. Limitations are a lack of reported statistics of the included studies and small sample sizes.
The first meta-analysis on reliability and validity of rasterstereography shows satisfactory results. Rasterstereography thus presents a reliable and valid alternative to classic radiological imaging technique to assess and evaluate spinal posture in patients with spinal pathologies. Further studies are needed, focusing on the measurement properties of both static and dynamic rasterstereographic measurements.
为临床医生和研究人员提供关于脊柱姿势的光栅立体测量的可靠性和有效性的荟萃分析。
全面的 PRISMA（系统评价和荟萃分析的首选报告项目）文献检索确定了 19 项符合条件的研究，这些研究评估了健康受试者和患有不同脊柱疾病的患者的静态光栅立体测量的可靠性和有效性。
我们的荟萃分析表明，光栅立体摄影术是一种可靠且有效的评估脊柱姿势参数的工具，尤其是胸椎后凸、腰椎前凸和脊柱侧凸，整体可靠性效应大小 rs>0.91，ps<0.001，整体有效性效应大小 rs>70，ps<0.001，与传统放射影像学技术相比。与健康对照组相比，在脊柱侧凸患者中，有效性更高。局限性在于纳入研究的报告统计数据和样本量小。
这是关于光栅立体摄影术可靠性和有效性的第一项荟萃分析，结果令人满意。因此，光栅立体摄影术为评估脊柱疾病患者的脊柱姿势提供了一种可靠且有效的替代传统放射影像学技术的方法。需要进一步的研究，重点关注静态和动态光栅立体测量的测量特性。
