The Adams Forward Bend Test recognizes the rotational aspect of the curve with the spine in flexion, and the AP X-ray measures the coronal plane deviation by using the Cobb Angle. However, modern techniques including CT-scan, biplanar radiograph, ultrasound, and surface topography allow the clinician to better evaluate and visualize the true 3-D nature of the spine. Surface Topography imaging uses the surface of the trunk to estimate the spine position using a mathematical algorithm that has been found to be accurate when compared to the radiologic Cobb Angle. The sagittal balance of the spine measured by surface topography is compared in three different situations, namely, "standing up straight," "standing relaxed," and "walking," which will help to best assess posture and risk of proximal junctional kyphosis before and after the treatment. Coronal imbalance (lateral deviation) and a range of maximal vertebral surface rotation (amplitude in either direction) are considered as the parameters with an excellent to good reproducibility. COP displacement or symmetry from the midline is used to measure the stability of the trunk. Therefore, those selected spine shape parameters and COP deviation would be considered as the best descriptors in the assessment of postural sway and outcome of PSSE in children with AIS.
Adams 前屈测试可识别脊柱弯曲时的旋转方面，而前后位 X 光片则使用 Cobb 角测量冠状面偏差。然而，包括 CT 扫描、双平面射线照相、超声和表面地形在内的现代技术使临床医生能够更好地评估和可视化脊柱的真实 3D 性质。表面地形成像使用躯干的表面，通过已被证明与放射科 Cobb 角相比准确的数学算法来估计脊柱位置。通过表面地形测量的脊柱矢状平衡在三种不同情况下进行比较，即“站直”、“放松站立”和“行走”，这有助于在治疗前后更好地评估姿势和近端交界性后凸的风险。冠状不平衡（侧向偏离）和最大椎体表面旋转范围（任一方向的幅度）被认为是具有极好到良好可重复性的参数。COP 从中线的位移或对称性用于测量躯干的稳定性。因此，那些选择的脊柱形状参数和 COP 偏差将被认为是评估 AIS 儿童姿势摆动和 PSSE 结果的最佳描述符。
