Background: Lower limb exoskeleton rehabilitation robot is a bionic robot, which is the
product of the combination of medical technology and robot technology, simulating human walking
movement. It can be mainly used for rehabilitation training of patients with lower limb dysfunction.
Objective: To provide an overview of recent lower limb exoskeleton rehabilitation robot and introduce
their respective characteristics and development.
Method: A recent lower limb exoskeleton rehabilitation robot is divided into passive drive, pneumatic
drive, hydraulic drive and motor drive. This paper reviews various representative patents related to lower
limb exoskeleton rehabilitation robot. The structural characteristics and applications of the typical
lower limb exoskeleton rehabilitation robots are introduced.
Results: The differences between different types of lower limb exoskeleton rehabilitation robots are
compared and analyzed, and the structural characteristics are concluded. The main problems in its development
are analyzed, the development trend is foreseen, and the current and future research of the
patents on lower limb exoskeleton rehabilitation robot is discussed.
Conclusion: There are a lot of patents and articles about the exoskeleton rehabilitation robots, however,
if these problems can be solved, such as small size, light weight and high power output are solved at the
same time, the consistency with human body will be advanced, with the combination of traditional rehabilitation
medicine. It will be possible to maximize the rehabilitation of the lower limbs.
