脊髓损伤会导致损伤平面以下肢体严重的感觉和运动功能障碍，对患者的生存质量造成了严重的影响。作为脊髓损伤的一种新型治疗技术，下肢外骨骼机器人受到了国内外学者的广泛关注。本文介绍了下肢外骨骼机器人的基本原理，简述了其在脊髓损伤患者行走功能恢复中的最新国内、外进展，进一步对该领域的研发提出新的展望，以期为脊髓损伤患者术后的康复基础研究及临床治疗方案提供一定的参考和借鉴。

Spinal cord injury can cause severe sensory and motor dysfunction in the limb below the level of injury，affecting the patient′s quality of life significantly. The lower limb exoskeleton robot has drawn a lot of attention from academics both domestically and internationally as a novel therapy method for spinal cord injury. This paper introduces the basic principles of lower limb exoskeleton robots，briefly describes its most recent domestic and international progress in the recovery of walking function in patients with spinal cord injury，and further puts forward new prospects for research and development in this field，in order to provide specific references and references for the basic research and clinical treatment plan of postoperative rehabilitation of patients with spinal cord injury.
