Design and optimization of the stationary lower limb gait rehabilitation exoskeleton

This paper examines the mechanical design and optimization of a stationary lower limb exoskeleton for paraplegic patients undergoing indoor gait rehabilitation. The prototype integrates frame segments, joint modules, and physical interfaces. The study first analyzes global and regional demand for exoskeletons to define patient needs, gait phases, and design criteria. A systematic methodology, based on literature reviews, guides the design and optimization process using CAD modeling and simulation software to test motion cycles and validate performance. The paper concludes with recommendations and technical guidelines for future exoskeleton development and research.
