大多数中风患者在身体的一侧会有永久性的虚弱（偏瘫），这降低了他们行走的能力。自主动力外骨骼已被提出作为解决这一问题的可能方案。对健康受试者的研究表明，辅助动力外骨骼具有改善步态的潜力，例如，通过减少步行的代谢成本。然而，只有少数研究是针对偏瘫患者进行的。因此，自主外骨骼改善这一人群步态的能力在很大程度上仍然未知。在这项研究中，我们评估了一名偏瘫患者在平地上行走时，有和没有自主动力髋关节外骨骼的自主选择步行速度。结果表明，所提出的外骨骼将自我选择的步行速度提高了约30%。生物力学分析表明，行走速度的增加是动力髋骨外骨骼的结果，使受试者在偏瘫的一侧可以迈出更长的步伐。本案例研究为未来外骨骼发展和临床研究设计提供了重要信息。
Most individuals suffering a stroke have permanent weakness on one side of the body (hemiparesis) that reduces their ability to ambulate. Autonomous powered exoskeletons have been proposed as a possible solution to this problem. Studies with healthy subjects show that assistive powered exoskeletons have the potential to improve gait, for example, by reducing the metabolic cost of walking. However, only a handful of studies have been conducted with individuals with hemiparesis. Thus, the ability of autonomous exoskeletons to improve gait in this population remains largely unknown. In this study, we assess self-selected walking speed with and without an autonomous powered hip exoskeleton in one individual with hemiparesis walking on level ground. Results show that the proposed exoskeleton improves self-selected walking speed by ~30%. The biomechanical analysis suggest that the increased walking speed is the result of the powered hip exoskeleton enabling the subject to take longer strides on the hemiparetic side. This case study provides important information to inform future exoskeleton development and clinical study design.
