Objective:To explore the application value of shear wave elastography(SWE)in evaluating the efficacy of acupuncture and core stability training in the treatment of nonspecific low back pain(NLBP).Methods:From January 2022 to December 2023,140 patients with NLBP and 70 healthy individuals were selected from our hospital.The SWV values of the psoas major muscle were compared between NLBP patients and healthy individuals.NLBP patients were randomly divided into two groups in a 1∶1 ratio using a single-blind method:the treatment group received acupuncture,and the control group underwent core stability training for the lumbar and back muscles.Both groups received two treatment courses.After the treatment courses,the SWV values,VAS scores,JOA scores and treatment improvement rates of the two groups before and after treatment were compared and statistically analyzed.Results:One patient in the NLBP treatment group and two patients in the control group dropped out,137 NLBP patients were included in the study.There were no statistically significant differences in age,gender,and BMI between the healthy group and the NLBP group,and there were no statistically significant differences in age,BMI,disease duration,and pre-treatment scores between the acupuncture treatment group and the core training control group(P>0.05).There was a significant difference in the SWV values of the psoas major muscle 1.5～2.5 cm beside the lumbar transverse process between the healthy group and NLBP patients(P<0.01).After two treatment courses,the SWV of the psoas major muscle decreased in both the treatment and control groups,with a more significant decrease in the treatment group.The difference in SWV values between the two treatment methods was significant(P<0.01).There were statistically significant differences in the scores and total effective rates before and after treatment between the two treatment methods(P<0.01).Conclusion:SWE technology can quantitatively detect the elasticity and hardness of the psoas major muscle,reflecting the treatment effects of acupuncture and core stability training on NLBP.Moreover,acupuncture treatment is more effective than exercise therapy for NLBP.
