We aimed to systematically review and quantify the association between acupuncture and pelvic floor muscle exercise and bladder dysfunction rehabilitation in individuals with spinal nerve injury. A meta-analysis was conducted using an evidence-based nursing analysis method based on clinical evidence. China National Knowledge Infrastructure, PubMed, VIP database, Wan Fang database, Cochrane Library, and other databases were searched by computer from January 1, 2000 to January 1, 2021. The literature was searched for clinical randomized controlled trials on acupuncture stimulation, pelvic floor muscle function training, and bladder function recovery training after spinal cord nerve injury. Two reviewers independently used The Cochrane Collaboration recommended randomized controlled trial risk of bias assessment tool to evaluate the quality of the literature. Then, the meta-analysis was performed using RevMan 5.3 software. A total of 20 studies were included, with a total sample size of 1468 cases, including 734 patients in the control group and 734 patients in the experimental group. The results of our meta-analysis showed that acupuncture treatment [OR = 3.98, 95% CI (2.77, 5.72), Z = 7.49, P < .001] and pelvic floor muscle treatment [OR = 7.63, 95% CI (4.47, 13.04), Z = 7.45, P < .001] was statistically significant. Acupuncture and pelvic floor muscle exercise are effective intervention and treatment methods, which have obvious effects on rehabilitation treatment of bladder dysfunction after spinal nerve injury.
