At present, the domestic and foreign research on the assistive standing system is mainly aimed at the disabled and lower limb rehabilitation trainers, suitable for ordinary elderly people's assistive system is still very few. This paper briefly introduces the structure and movement mode of assistive standing systems at home and abroad, compares and analyzes the characteristics and performance of different assistive devices, and summarizes the adaptability and effectiveness of different assistive movement trajectories. At the same time, the research on the assistive standing device and its movement trajectory with the elderly as the main object in the future is proposed and prospected.
