This study focuses on the fabrication of an anisotropic textile brace that exerts corrective forces based on the three-point pressure system to treat scoliosis, which is a medical condition that involves deformity of the spine. The design and material properties of the proposed anisotropic textile brace are discussed in detail here. A case series study with 5 scoliosis patients has been conducted to investigate the immediate in-brace effect and biomechanics of the proposed brace. Radiographic examination, three-dimensional scanning of the body and interface pressure measurements have been used to evaluate the immediate effect of the proposed brace on reducing the spinal curvature and asymmetry of the body contours and its biomechanics. The results show that the proposed brace on average reduces the spinal curvature by 11.7° and also increases the symmetry of the posterior trunk by 14.1% to 43.2%. The interface pressure at the corrective pad ranges from 6.0 to 24.4 kPa. The measured interface pressure shows that a sufficient amount of pressure has been exerted and a three-point pressure distribution is realized to reduce the spinal curvature. The obtained results indicate the effectiveness of this new approach which uses elastic textile material and a hinged artificial backbone to correct spinal deformity.

对脊柱弯曲施加矫正力的各向异性纺织支具的设计与制造

这项研究的重点是制造一种各向异性纺织支架,该支架基​​于三点压力系统施加矫正力来治疗脊柱侧弯,这是一种涉及脊柱畸形的医学状况。此处详细讨论了所提出的各向异性纺织支架的设计和材料特性。已经对 5 名脊柱侧弯患者进行了案例系列研究,以调查所提议的支具的即时支具内效应和生物力学。射线照相检查、身体三维扫描和界面压力测量已被用于评估所提议的支架对减少脊柱弯曲和身体轮廓不对称及其生物力学的直接影响。结果表明,所提出的支具平均将脊柱弯曲减少了 11。7° 并且还将后躯干的对称性增加了 14.1% 到 43.2%。矫正垫的界面压力范围为 6.0 至 24.4 kPa。测量的界面压力表明已经施加了足够的压力并且实现了三点压力分布以减少脊柱弯曲。获得的结果表明这种新方法的有效性,该方法使用弹性纺织材料和铰接的人工骨干来矫正脊柱畸形。
