Abstract：
This study aimed to investigate the effectiveness of 3D postural correction (3DPC) using corrective cushions (CCs) and abdominal muscle contraction (AMC) on the thickness symmetry of the transversus abdominis (TrA) and spinal alignment in patients with idiopathic scoliosis (IS). In the first experiment, ultrasound measurements were taken of the TrA thickness on both the convex and concave sides of the lumbar curve in the supine position during AMC and non-AMC without 3DPC, and during AMC and non-AMC with 3DPC using CCs, in 11 IS patients. In the second experiment, 37 IS patients participated in a four-week 3DPC exercise program that aimed to maintain TrA thickness symmetry based on the results of the first experiment. The study found that TrA thickness symmetry significantly increased after 3DPC using CCs and combined with AMC (p < 0.05). Additionally, the Cobb angles and trunk rotation angles showed significant decreases, and trunk expansion showed a significant increase (p < 0.05). These results indicate that the simultaneous application of 3DPC and AMC is the most effective way to achieve TrA thickness symmetry in IS patients. Therefore, 3DPC and AMC should be considered as crucial elements in exercise interventions for IS patients.
摘要：
本研究旨在探讨使用矫正垫（CC）和腹肌收缩（AMC）的3D姿势矫正（3DPC）对特发性脊柱侧凸（IS）患者腹横肌（TrA）和脊柱对齐的厚度对称性的有效性。在第一个实验中,在AMC和无3DPC的非AMC中仰卧位时，对腰椎曲线的凸侧和凹侧进行了超声测量，在AMC和非AMC与使用CC的3DPC期间，在11个IS患者中。在第二个实验中,37名IS患者参加了为期四周的3DPC锻炼计划，该计划旨在根据第一个实验的结果保持TrA厚度对称性。研究发现，使用CC并结合AMC的3DPC后，TrA厚度对称性显着增加（p<0.05）。此外,Cobb角和躯干旋转角显着减小，躯干扩张显著增加(p<0.05)。这些结果表明，同时应用3DPC和AMC是实现IS患者TrA厚度对称的最有效方法。因此,3DPC和AMC应被视为IS患者运动干预的关键因素。
