本研究旨在评估Scoliometer®，这是一种测量脊柱侧凸患者躯干轴向旋转的仪器。目的包括确定1）Scoliometer ®筛查能力和有效性，以及2）Scoliometer®测量的评估者内和评估者间可靠性。由两名评估者对65名特发性脊柱侧凸患者进行的Scoliometer®测量与椎骨（椎弓根）旋转和侧弯的影像学评估（Cobb方法）相关。与椎弓根旋转的相关性范围为0.32至0.46，与Cobb角的相关性范围为0.46至0.54。频率分析显示Scoliometer®具有相对较好的特异性、敏感性和预测能力。评价者内和评价者间的信度系数较高（r= 0.86 - 0.97）。这些结果表明良好的测量再现性。低于最佳的方法间相关系数表明，Scoliometer®测量的有效性不足以单独使用该方法来确定患者诊断和管理。然而，根据正频率分析，使用这一工具作为筛选手段是适当的。
This study was designed to evaluate the Scoliometer®, an instrument that measures axial trunk rotation in individuals with scoliosis. The objectives included determining 1) the Scoliometer's® screening capability and validity and 2) the intrarater and interrater reliability of Scoliometer® measurements. Scoliometer® measurements made by two raters on 65 persons with idiopathic scoliosis were correlated with radiographic assessment of vertebral (pedicle) rotation and lateral curvature (Cobb method). Correlations ranged from .32 to .46 with pedicle rotation and from .46 to .54 with the Cobb angle. Frequency analysis revealed relatively good specificity, sensitivity, and predictive capability of the Scoliometer®. Intrarater and interrater reliability coefficients were high (r= .86–.97). These results indicate good measurement reproducibility. The less-than-optimal between-method correlation coefficients suggest that the validity of Scoliometer® measurements is not sufficient to use this method alone for determining patient diagnosis and management. Based on the positive-frequency analysis, however, the use of this tool as a screening device would be appropriate.
