Abstract：
UNASSIGNED: Scoliosis is a multifaceted three-dimensional deformity that significantly affects patients\' balance function and walking process. While existing research primarily focuses on spatial and temporal parameters of walking and trunk/pelvic kinematics asymmetry, there remains controversy regarding the symmetry and regularity of bilateral lower limb gait. This study aims to investigate the symmetry and regularity of bilateral lower limb gait and examine the balance control strategy of the head during walking in patients with idiopathic scoliosis.
UNASSIGNED: The study involved 17 patients with idiopathic scoliosis of Lenke 1 and Lenke 5 classifications, along with 17 healthy subjects for comparison. Three-dimensional accelerometers were attached to the head and L5 spinous process of each participant, and three-dimensional motion acceleration signals were collected during a 10-meter walking test. Analysis of the collected acceleration signals involved calculating five variables related to the symmetry and regularity of walking: root mean square (RMS) of the acceleration signal, harmonic ratio (HR), step regularity, stride regularity, and gait symmetry.
UNASSIGNED: Our analysis reveals that, during the walking process, the three-dimensional motion acceleration signals acquired from the lumbar region of patients diagnosed with idiopathic scoliosis exhibit noteworthy disparities in the RMS of the vertical axis (RMS-VT) and the HR of the vertical axis (HR-VT) when compared to the corresponding values in the healthy control (RMS-VT: 1.6 ± 0.41 vs. 3 ± 0.47, P < 0.05; HR-VT: 3 ± 0.72 vs. 3.9 ± 0.71, P < 0.05). Additionally, the motion acceleration signals of the head in three-dimensional space, including the RMS in the anterior-posterior and vertical axis, the HR-VT, and the values of step regularity in both anterior-posterior and vertical axis, as well as the values of stride regularity in all three axes, are all significantly lower than those in the healthy control group (P < 0.05).
UNASSIGNED: The findings of the analysis suggest that the application of three-dimensional accelerometer sensors proves efficacious and convenient for scrutinizing the symmetry and regularity of walking in individuals with idiopathic scoliosis. Distinctive irregularities in gait symmetry and regularity manifest in patients with idiopathic scoliosis, particularly within the antero-posterior and vertical direction. Moreover, the dynamic balance control strategy of the head in three-dimensional space among patients with idiopathic scoliosis exhibits a relatively conservative nature when compared to healthy individuals.

摘要：
■脊柱侧凸是一种多方面的三维畸形，显着影响患者的平衡功能和行走过程。虽然现有的研究主要集中在步行和躯干/骨盆运动学不对称性的空间和时间参数，关于双侧下肢步态的对称性和规律性仍存在争议。本研究旨在探讨特发性脊柱侧凸患者双侧下肢步态的对称性和规律性，并探讨行走过程中头部的平衡控制策略。
■该研究涉及17例特发性脊柱侧凸患者，包括Lenke1和Lenke5分类，与17名健康受试者进行比较。每个参与者的头部和L5棘突都安装了三维加速度计，和三维运动加速度信号被收集在一个10米的步行测试。分析收集到的加速度信号，包括计算与步行的对称性和规律性相关的五个变量：加速度信号的均方根（RMS），谐波比（HR），步骤规律性，步幅规律性,和步态对称。
■我们的分析表明，在行走过程中,与健康对照中的相应值相比，从诊断为特发性脊柱侧凸的患者的腰椎区域获得的三维运动加速度信号在垂直轴RMS（RMS-VT）和垂直轴HR（HR-VT）方面表现出值得注意的差异（RMS-VT：1.6±0.41vs.3±0.47，P<0.05；HR-VT：3±0.72vs.3.9±0.71,P<0.05)。此外,头部在三维空间中的运动加速度信号，包括前后轴和垂直轴的RMS，HR-VT,以及前后轴和垂直轴上的阶跃规律性值，以及所有三个轴的步幅规律性值，均显著低于健康对照组(P<0.05)。
■分析结果表明，三维加速度计传感器的应用被证明是有效且方便的，可以仔细检查特发性脊柱侧凸患者行走的对称性和规律性。特发性脊柱侧凸患者的步态对称性和规律性明显不规则，特别是在前后和垂直方向。此外，与健康个体相比，特发性脊柱侧凸患者头部在三维空间中的动态平衡控制策略表现出相对保守的性质。
