[Objective]Based on the propensity score matching method to explore the therapeutic effect of lever positioning manipulation in the treatment of L4/5 different types of lumbar disc herniation.[Methods]A prospective cohort design was used to select 122 patients with L4/5 lumbar disc herniation and divide them into unilateral group,bilateral group and central group.Samples with balanced covariates were obtained after matching,including 36 patients in unilateral group,35 patients in bilateral group and 35 patients in central group.All patients in the three groups were treated with leverage positioning technique,and all patients in the three groups were treated 3 times a week,once every other day,for a total of 2 weeks.Pain Visual Analogue Scale(VAS)score and Japanese Orthopaedic Association(JOA)score were observed before and after treatment to evaluate the differences in the postoperative effects of the three groups.[Results]The covariates of age,sex,course of disease,VAS score and JOA score were all balanced after matching(P>0.05).The results of following-up after 2 weeks and 6 months of treatment showed that the VAS score and JOA score were statistically significant(P<0.05),the distant and near term curative effect of lever positioning manipulation in the treatment of unilateral lumbar disc herniation was better than bilateral and central disc herniation(P<0.05).[Conclusion]The clinical efficacy of unilateral lumbar disc herniation is superior to bilateral and central disc herniation in the treatment of the same segment of lumbar disc herniation with leverage positioning manipulation.
