The efficacy of exoskeleton robotic training on ambulation recovery in patients with spinal cord injury: A meta-analysis.

Abstract

Objective: To discuss the efficacy of exoskeleton robotic training on ambulation recovery in patients with spinal cord injury (SCI).Methods: PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched systematically from their inception to April 2022 for studies on exoskeleton robotic training in patients with SCI. The language was restricted to English. The retrieved studies were screened to select eligible clinical trials. Meta-analysis was performed using Review Manager 5.4.Results: Eleven randomized clinical trials (RCTs) involving 456 participants were included in the meta-analysis. The results of the meta-analysis showed that exoskeleton robotic training was more effective in improving FIM [SMD = 0.58, 95%CI = (0.07, 1.10), P = 0.03], LEMS [MD = 4.64, 95%CI = (3.58, 5.70), P<0.05], MAS [MD = 0.76, 95%CI = (0.48, 1.03), P<0.05] and BBS [MD = -3.11, 95%CI =  (-12.59, 6.36), P<0.05] in patients with SCI, compared to conventional gait training(CGT). Subgroup analysis showed that the exoskeleton robotic could significantly improve the walking endurance and walking speed of patients with a duration of injury within 6 months. The sensitivity of inverted funnel plot analysis is low, suggesting that the analysis results of this study are relatively stable.Conclusion: Exoskeleton robotic training improves ambulation in patients with SCI, especially for patients with a course of injury within six months.
