Energy Efficiency of Gait Rehabilitation Robot: A Review

Gait rehabilitation robots have been reported to reduce impairment and regain functional abilities of gait disorder significantly. While energy efficiency is essential in the process of gait rehabilitation, few gait rehabilitation robots can achieve it. This paper aims to emphasize the importance of energy efficiency on the development of gait rehabilitation robots and conduct a view of rehabilitation training approaches as well as robots. Gaps and conflicts in traditional rehabilitation robots are analyzed based on the rehabilitation requirements and energy efficiency. While related research in reduction on energy consumption of human and optimization of human with device together during walking, is summarized. Finally, we discuss and highlight the future directions regarding the energy-efficient feature in gait rehabilitation robots.
