Objective：To observe the clinical effect of four-dimensional traction combined with Shentong Zhuyu tang for lumbar disc herniation of blood stasis type.MethodsDivided 70 cases of patients with lumbar disc herniation of blood stasis type into the experiment group and the control group randomly，35 cases in each group.The experiment group receivedfour-dimensional traction combined with Shentong Zhuyu tang for treatment，while the control group received Tuina technique.Observed changes of scores of visual analogue scales(VAS)，Japanese Orthopedic Association score(JOA score)and Oswestry disability index scale(ODI)before and after treatment in both groups.ResultsBefore treatment，no significant difference was found in the comparison of scores of VAS，JOA and ODI between the two groups(P ＞ 0.05).After treatment，scores of VAS and ODI in both groups were decreased when compared with those before treatment，while JOA scores in both groups were increased when compared with those before treatment，differences being significant(P ＜ 0.05).Scores of VAS and JOA in the experiment group were lower than those in the control group，while JOA scores in the experiment group were higher than those in the control group(P＜0.05).Clinical effect in the experiment group was better than that in the control group(Z=-2.045，P=0.041).ConclusionThe therapy of four-dimensional traction combined with Shentong Zhuyu tang has a significant effect in treating lumbar disc herniation of blood stasis type，which is worthy of clinical promotion and application.
