Individuals with spinal cord injuries (SCI) face substantial mobility challenges that affect their independence and quality of life. Traditional medial linkage reciprocal gait orthoses (MLRGO) often lack efficiency in enhancing mobility and stability. This study introduces the Advanced MLRGO, designed to overcome these limitations and improve walking function for SCI patients. The Advanced MLRGO was developed using orthopedic engineering and biomechanics principles, with detailed simulations performed in COMSOL Multi-physics to evaluate force distribution and resistance. A clinical trial involving five individuals with SCI was conducted to compare the performance of the Advanced MLRGO against the Prime-Walk orthosis and the standard MLRGO. Results showed that the MLRGO system significantly improved walking speed ( = 0.03) and distance traveled ( = 0.04) compared to the Prime-Walk. The Advanced MLRGO also exhibited notable enhancements over the standard MLRGO, showing increased walking speed ( = 0.033) and distance ( = 0.026), as well as reduced donning time ( = 0.048). These findings indicate that the Advanced MLRGO significantly enhances mobility and independence for individuals with thoracic SCI. Future research should focus on improving doffing efficiency and assessing individual user experiences to maximize these benefits.
脊髓损伤（SCI）患者面临着严重的行动挑战，这影响了他们的独立性和生活质量。传统的内侧联动往复式步态矫形器（MLRGO）在提高行动能力和稳定性方面往往缺乏效率。本研究推出了先进的MLRGO，旨在克服这些局限性并改善SCI患者的行走功能。先进的MLRGO是利用矫形工程和生物力学原理开发的，在COMSOL多物理场中进行了详细的模拟，以评估力的分布和阻力。进行了一项涉及五名SCI患者的临床试验，以比较先进的MLRGO与Prime-Walk矫形器和标准MLRGO的性能。结果表明，与Prime-Walk相比，MLRGO系统显著提高了行走速度（P = 0.03）和行走距离（P = 0.04）。先进的MLRGO与标准MLRGO相比也有显著提升，显示出行走速度增加（P = 0.033）和距离增加（P = 0.026），以及穿戴时间减少（P = 0.048）。这些发现表明，先进的MLRGO显著提高了胸段SCI患者的行动能力和独立性。未来的研究应专注于提高脱卸效率并评估个体用户体验，以最大化这些益处。
