Abstract：Objective To compare the clinical efficacy of resistance breathing training versus diaphragmatic breathing,in conjunction with core stability training,for the treatment of chronic non-specific low back pain(CNL-BP).Methods From July 2022 to December 2023,52 patients with chronic non-specific low back pain(CNLBP)were selected from the People's Hospital affiliated with Fujian University of Traditional Chinese Medicine.They were randomly assigned to either the experimental group(n=26)or the control group(n=26)using a random number table method.Both groups received conventional rehabilitation therapy combined with core stability training.The control group underwent diaphragmatic breathing training,while the experimental group received resistance breathing training,performed 5 times per week for 4 weeks.Evaluations were conducted before and after treatment using Visual Analog Scale(VAS)scores,Oswestry Disability Index(ODI)scores,and the flexion-relaxation ratio(FRR)of the erector spinae muscles measured by surface electromyography.Results Post-treatment,both groups showed significant reductions in VAS scores(P＜0.001)and ODI scores(P＜0.001).However,there were no statistically significant differences in VAS and ODI scores between the two groups after treatment(P＞0.05).Both groups exhibited significant improvements in FRR,with the experimental group showing superior improvement compared to the control group,which was statisti-cally significant(P＜0.001).Conclusion Core stability training combined with breathing exercises can improve pain and functional outcomes in CNLBP patients,restoring the flexion-relaxation phenomenon.Compared to diaphragmatic breathing,resistance breathing training more effectively enhances the flexion-relaxation ratio of the erector spinae mus-cles,activates deep core stabilizing muscles,relaxes tense lumbar and back muscles,improves the self-regulation of lumbar and back muscle contraction,and restores the flex-ion-relaxation phenomenon.
