The conventional rigid spinal orthosis and the flexible spinal orthosis, SpineCor, have different treatment principles in the management of adolescent idiopathic scoliosis (AIS). These may influence the patients' gait pattern and clinical outcome. In this study, gait analysis on patients with AIS undergoing these two orthotic interventions were conducted. The patients' lower limb kinematic and kinetic data during level walking were collected using a motion analysis system and two force platforms in four test conditions: pre-intervention, having used the orthosis for 1 month and 1 year (in and out of the orthosis). Twenty-one subjects were randomly assigned to the rigid spinal orthosis group (10 subjects) and the SpineCor group (11 subjects). Neither group showed gait asymmetry when comparing the convex and concave sides in the four test conditions. However, significant reduction in the range of motion of the pelvis and hip joints in the coronal plane were found. Although patients with AIS undergoing these two orthotic interventions showed significant changes in walking pattern within the study period, their long-term effect on gait and function requires further investigation through long-term prospective studies.
传统的刚性脊柱矫形器和柔性脊柱矫形器SpineCor在青少年特发性脊柱侧凸（AIS）的治疗原则上有所不同。这些可能会影响患者的步态模式和临床结果。在本研究中，对接受这两种矫形干预的AIS患者进行了步态分析。在四种测试条件下，使用运动分析系统和两个测力平台收集患者在平地行走时的下肢运动学和动力学数据：干预前、使用矫形器1个月和1年（佩戴和不佩戴矫形器）。21名受试者被随机分配到刚性脊柱矫形器组（10名受试者）和SpineCor组（11名受试者）。在四种测试条件下比较凸侧和凹侧时，两组均未显示步态不对称。然而，发现冠状面骨盆和髋关节的运动范围显著减小。尽管接受这两种矫形干预的AIS患者在研究期间行走模式有显著变化，但它们对步态和功能的长期影响需要通过长期前瞻性研究进一步调查。
