| Objective: To determine the intervention effect of non-surgical spinal decompression system (SDS) on lumbar disc herniation (LDH). Methods: PubMed, Cochrane Library, Embase, Web of Science, CNKI, Wanfang Database, Chinese Biomedical Literature Database (CBM), and VIP Database which had published randomized controlled trials on SDS intervention of LDH were searched. The search time limit was from the establishment of the database to August 21, 2023. At least 2 researchers screened the literature and extracted the data. Cochrane Handbook 5.1.0 and the Jadad scale were used to evaluate the quality of the included studies. Revman5.4 software was used to analyze the results of the Meta-analysis, and stata14.0 software was used to assess the risk of bias. Results: A total of 16 studies involving 965 patients were included. The results showed that SDS intervention could significantly reduce the score of patients with pain (95% CI ［-1.05~-0.75］; SMD=-0.90, P<0.001). In terms of lumbar function improvement, SDS intervention could increase AEMG of erector spinae (95% CI ［6.49~19.51］; MD=13.00; P<0.001), AEMG of the multifidus (95% CI ［6.62~19.97］; MD=13.30; P<0.001), mean MPFs of erector spinae (95% CI ［0.05~0.09］; MD=0.07; P<0.001), mean MPFs of the multifidus (95% CI ［0.05~0.10］; MD=0.07; P<0.001), reduced ODI score (95% CI ［-1.27~-0.71］; SMD=0.99; P<0.001). SDS intervention could significantly reduce the intervertebral disc herniation index (95% CI ［-2.87~-0.07］; SMD=-1.82; P<0.001), from the posterior margin of the vertebral body to the apex of the protrusion (95% CI［-1.11~-0.79］; MD=-0.95; P<0.001), but the intervention effect was not significant in disc height (95% CI［-0.38~1.19］; MD=0.41; P=0.31). In terms of effective rate, SDS intervention could significantly improve the treatment effect of patients (95% CI ［1.16~1.42］; RR=1.28; P<0.001). Conclusion:SDS or combined therapy can relieve the pain, improve the lumbar dysfunction, improve the function of paraspinal muscles, relieve the degree of intervertebral disc herniation, and improve the therapeutic effect of LDH patients, but the effect on improving the height of intervertebral disc is not obvious. |
