Engineering Application of Lower Limb Exoskeleton System in Clinical Rehabilitation

Spinal cord injuries and strokes can severely affect the function of the lower limbs, which in turn reduces people's quality of life. Lower limb function is an important part of daily life, and therefore, clinical treatment of these disorders is aimed at restoring the patient's ability to walk normally. Due to the great potential of lower limb exoskeletons in the clinical rehabilitation of these diseases, the number of studies on lower limb exoskeletons has increased a lot in recent years. However, there are some gaps between the current research and clinical practice of lower limb exoskeletons in the laboratory, and this paper provides some lower limb exoskeletons based on clinical rehabilitation practice to bridge the gap between theory and practice. This review article mentions the advantages and disadvantages of several different driving modes of lower limb exoskeletons, and focuses on the design of rigid electric drive lower limb exoskeletons and their role in clinical rehabilitation. This article compares the rehabilitation methods involved in the lower extremity exoskeleton with traditional treatment methods, and illustrates that the lower extremity exoskeleton can better assist patients in gait recovery in some cases.
