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). Correlation 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.
本研究旨在评估脊柱侧凸测量仪，这是一种用于测量脊柱侧凸患者躯干轴向旋转的仪器。研究目的包括确定：1）脊柱侧凸测量仪的筛查能力和有效性；2）该测量仪测量结果的测量者内和测量者间可靠性。两位测量者对65例特发性脊柱侧凸患者进行的脊柱侧凸测量仪测量结果，与椎体（椎弓根）旋转和侧方弯曲（Cobb法）的影像学评估结果进行了相关性分析。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，脊柱侧凸测量仪具有相对良好的特异性、敏感性和预测能力。测量者内和测量者间可靠性系数较高（r = 0.86 - 0.97）。这些结果表明测量具有良好的可重复性。方法间相关性系数未达最佳，这表明脊柱侧凸测量仪测量结果的有效性不足以单独使用该方法来确定患者的诊断和治疗方案。然而，基于阳性频率分析，将该工具用作筛查设备是合适的。
