Abstract： Objective： To observe the clinical effect of the combined use of micro-needle-knife therapy and abdominal acupuncture and traction on patients with lumbar disc herniation. Methods： A total of 180 patients with lumbar disc herniation treated in the department of acupuncture and massage of Kanmen Branch of Health Community Group of The People's Hospital of Yuhuan from May 2022 to May 2023 were included as the study objects and divided into the control group and the observation group by the random number table method，with 90 cases in each group. Both groups were treated with abdominal acupuncture and traction，and the observation group was additionally treated with micro-needle-knife therapy. Both groups were treated for two months. The traditional Chinese medicine（TCM） syndrome scores，quality of life [scores of Short Form（ SF-36） Health Survey]，lumbar pain [scores of Visual Analogue Scale （VAS）]， self-care ability [scores of Activity of Daily Living （ADL）]， lumbar function [scores of Japanese Orthopaedic Association （JOA） of lumbar vertebrae and Oswestry Disability Index （ODI）] and the levels of serum β -endorphin and 5-hydroxytryptamine before and after treatment，and the clinical effects were compared between the two groups. Results： After treatment， the total effective rate in the observation group was higher than that in the control group （P＜0.05）. The scores of cold pain in the lower back and legs， heaviness in the lower back and legs， restricted movement when turning， and limb numbness in the two groups were down-regulated when compared with those before treatment （P＜0.05），and the above four TCM syndrome scores in the observation group were lower than those in the control group （P＜0.05）. The SF-36 scores of physical functioning，social functioning，bodily pain and general health in the two groups were elevated when compared with those before treatment （P＜0.05），and the above four scores in the observation group were higher than those in the control group （P＜0.05）. The VAS scores in the two groups were reduced when compared with those before treatment， and the ADL scores were elevated when compared with those before treatment，differences being significant（ P＜0.05）；the VAS score in the observation group was lower than that in the control group， and the ADL score was higher than that in the control group， differences being significant （P＜0.05）. The JOA scores in both groups were increased when compared with those before treatment，and the ODI scores were decreased when compared with those before treatment，differences being significant （P＜0.05）； the JOA score in the observation group was higher than that in the control group，and the ODI score was lower than that in the control group，differences being significant（ P＜0.05）. The serum β-endorphin levels in the two groups were upregulated when compared with those before treatment，and the serum 5-hydroxytryptamine levels were dwindled when compared with those before treatment， differences being significant （P＜0.05）； the serum β-endorphin level in the observation group was higher than that in the control group，and the serum 5-hydroxytryptamine level was lower than that in the control group，differences being significant （P＜0.05）. Conclusion：The combined use of micro-needleknife therapy and abdominal acupuncture and traction can enhance the clinical effect on lumbar disc herniation，which can effectively immigrate the chronic low back pain and improve the self-care ability，lumbar function and quality of life.
