Abstract：Objective To explore the effect of respiratory training based on core stabilization training on lumbar disc herniation. Methods From January,2023 to October,2024,96 patients with lumbar disc herniation admitted to the First Affiliated Hospital of Bengbu Medical University were divided into control group (n=32),core group (n=32) and respira-tory group (n=32).All the groups underwent conventional rehabilitation therapy,with core stabilization training in the core group and respiratory training combined with core stabilization training in the respiratory group,addi-tionally,for four weeks.Before and after training,the scores of Visual Analogue Scale,Japanese Orthopaedic As-sociation (JOA) and Oswestry Dysfunction Index (ODI) were compared,the average electromyographic value (AEMG) and root mean square (RMS) value of the multifidus and transversus abdominis were detected by sur-face electromyography (sEMG);and the thickness of the multifidus and transversus abdominis were measured by musculoskeletal ultrasonography bilaterally. Results The intra-group effect (F>597.796,P<0.001),inter-group effect (F>16.535,P<0.001) and interaction effect (F>49.622,P<0.001) were significant in the scores of VAS,JOA and ODI;which were better in the respiratory group than in the control group and the core group (P<0.05),and were better in the core group than in the con-trol group (P<0.001).The intra-group effect (F>7971.631,P<0.001),inter-group effect (F>177.760,P<0.001) and interaction effect (F>478.771,P<0.001) were significant in the thickness of the transversus abdomi-nis and multifidus;which were better in the respiratory group than in the control group and the core group (P<0.001),and were better in the core group than in the control group (P<0.001).The intra-group effect (F>144303.007,P<0.001),inter-group effect (F>1495.458,P<0.001) and interaction effect (F>3121.361,P<0.001) were significant in the RMS of the multifidus and transversus abdominis;which were better in the respira-tory group than in the control group and the core group (P<0.001),and were better in the core group than in the control group (P<0.001).The intra-group effect (F>1890.532,P<0.001),inter-group effect (F>607.132,P<0.001) and interaction effect (F>824.923,P<0.001) were significant in the AEMG of the multifidus and trans-versus abdominis;which were better in the respiratory group than in the control group and core group (P<0.001),and were better in the core group than in the control group (P<0.001). Conclusion Core training combined with respiratory training can more effectively reduce pain and improve dysfunction by enhancing the strength and control of the core muscles,thus improving the quality of life of patients with lum-bar disc herniation.
