Abstract
BACKGROUND: Spinal cord injury (SCI) is a type of damage to the central nervous system (CNS) caused by various factors. The secondary injury of SCI is more complicated. Studies have found that electroacupuncture can help the recovery of nerve function during spinal cord injury. Therefore, this study explored the efficacy of electroacupuncture on complications after spinal cord injury through meta-analysis. METHODS: Relevant literatures published from January 2010 to March 2022 were searched with "Electric acupuncture, Spinal cord injury, Neural functional recovery, Spinal cord injury in rats, Neuronal Signaling" as search words. The risk of bias of included references was analyzed and assessed using RevMan 5.3 software and Stata software. Heterogeneity between studies was assessed using the Q-test and heterogeneity (I (2)). RESULTS: There was no heterogeneity among the study groups. The comparison on the therapeutic effects of electroacupuncture and conventional therapy suggested that electroacupuncture was more effective for nerve recovery after spinal cord injury than conventional therapy. It can better improve the recovery of motor function after spinal cord injury in rats. On the other hand, SCI+EA had a good inhibitory effect on the expression of RhoA protein signal in rats and had a positive effect on the signal pathway. Discussion. The results of meta-analysis confirmed that electroacupuncture was more effective than conventional therapy in inhibiting pathways.
