Influence of a Soft Robotic Suit on Metabolic Cost in Long-Distance Level and Inclined Walking

الملخص EN

Metabolic cost during walking is positively linked to exercise intensity.

For a walking assistive device, one of the major aims should be the maximization of wearers’ metabolic benefits for different walking situations.

Toward this goal, this paper experimentally evaluates the influence of an authors’ soft robotic suit, which has been developed to assist hip flexion for energy-efficient walking of elderly persons in daily life activities, on metabolic cost reduction in the long-distance level and inclined walking.

Experiment results show that, for a 79-year-old healthy male subject, the robotic suit significantly reduced metabolic cost in the condition of the robotic suit worn and powered on compared with the condition of worn but powered off.
