In this paper, we explore the effect of residual hip assistance in one above-knee amputee subject using a novel lightweight powered hip exoskeleton. Differently from a powered prosthesis, a powered hip exoskeleton adds mass proximally. Thus, we expect that the negative effect of the added mass will be lower for a powered hip exoskeleton than a powered ankle and knee prosthesis. Consequently, residual-hip assistance may more easily lead to a net reduction of metabolic effort. To preliminarily assess this hypothesis, we measured the physiological cost index (PCI) while an above-knee subject walked with and without a powered hip exoskeleton. Experimental results show 20.5% reduction of PCI when walking with the powered hip exoskeleton.
在本文中，我们使用一种新型轻质动力髋关节外骨骼，探究了其对一名膝上截肢者残髋辅助的效果。与动力假肢不同，动力髋关节外骨骼在近端增加了质量。因此，我们预计，对于动力髋关节外骨骼而言，增加质量带来的负面影响要低于动力踝膝关节假肢。所以，残髋辅助可能更容易使代谢消耗实现净减少。为了初步评估这一假设，我们测量了一名膝上截肢者在佩戴和不佩戴动力髋关节外骨骼行走时的生理成本指数（PCI）。实验结果表明，佩戴动力髋关节外骨骼行走时，PCI降低了20.5%。
