中风是严重步态障碍的主要原因，恢复行走能力是物理治疗干预的主要目标。软机器人外装护具是便携式、轻便且不显眼的辅助装置，旨在通过在步行训练期间促进更自然的瘫痪肢体功能来改善中风后个体的移动性。然而，目前尚不清楚使用软机器人外装的长期步态训练是否会在临床上影响中风后的步态功能和运动质量。这项初步研究的目的是检查软机器人外装增强步态训练对慢性卒中后个体的临床和生物力学步态结果的治疗效果。5名中风后患者接受了高强度的步态训练，并在6-8周的时间内进行了18次训练。在基线、中点和完成时测量基于性能的临床结局和生物力学步态质量参数。观察到步行速度（< 0.05）和耐力（< 0.01）以及其他传统步态相关结局的临床有意义的改善。包括髋关节（< 0.01）和膝关节（< 0.05）屈曲/伸展在内的步态质量测量显示出对称方式（< 0.05）的运动范围增加。我们还观察到双侧踝关节角速度增加（< 0.05），表明行走功能的生物力学改善。本研究的结果提供了初步证据，表明软机器人外装护具可以成为在临床环境中增强高强度步态训练的有用工具。这项研究证明了更广泛的研究软外套技术与更大的中风后人口更可靠的推广。试验注册本研究在ClinicalTrials.gov注册（ID：NCT 04251091）
Stroke is a leading cause of serious gait impairments and restoring walking ability is a major goal of physical therapy interventions. Soft robotic exosuits are portable, lightweight, and unobtrusive assistive devices designed to improve the mobility of post-stroke individuals through facilitation of more natural paretic limb function during walking training. However, it is unknown whether long-term gait training using soft robotic exosuits will clinically impact gait function and quality of movement post-stroke. The objective of this pilot study was to examine the therapeutic effects of soft robotic exosuit-augmented gait training on clinical and biomechanical gait outcomes in chronic post-stroke individuals. Five post-stroke individuals received high intensity gait training augmented with a soft robotic exosuit, delivered in 18 sessions over 6–8 weeks. Performance based clinical outcomes and biomechanical gait quality parameters were measured at baseline, midpoint, and completion. Clinically meaningful improvements were observed in walking speed ( < 0.05) and endurance ( < 0.01) together with other traditional gait related outcomes. The gait quality measures including hip ( < 0.01) and knee ( < 0.05) flexion/extension exhibited an increase in range of motion in a symmetric manner ( < 0.05). We also observed an increase in bilateral ankle angular velocities ( < 0.05), suggesting biomechanical improvements in walking function. The results in this study offer preliminary evidence that a soft robotic exosuit can be a useful tool to augment high intensity gait training in a clinical setting. This study justifies more expanded research on soft exosuit technology with a larger post-stroke population for more reliable generalization.
