Objective:To evaluate the clinical efficacy of fast filiform needling in treatment of chronic nonspecific low back pain(CNLBP)and to observe its effects on muscle function using shear wave elastography(SWE).Methods:A total of 104 patients with CNLBP were randomly assigned into the study group and the control group,with 48 patients in each group after 4 cases dropped off per group.The control group received conventional acupuncture,whereas the study group received fast filiform needling.Both groups underwent treatment for 2 weeks.The Visual Analogue Scale(VAS)was used to assess lumbar pain severity,and the Japanese Orthopaedic Association(JOA)score was adopted to evaluate lumbar spine function.Muscle thickness at the affected side of the L3 level was measured using conventional musculoskeletal ultrasound to assess muscle edema,while SWE was used to determine shear wave velocity(SWV)to evaluate muscle elasticity.Clinical efficacy was also assessed in the two groups.Results:The total effective rate was 93.75%(45/48)in the study group,which was higher than 79.17%(38/48)in the control group(P<0.05).The VAS scores were decreased,the JOA scores were increased,the muscle thickness were reduced,and the SWV values were decreased in both groups after the treatment(P<0.01);the improvements in the study group were more significant than those in the control group(P<0.05,P<0.01).Conclusion:Fast filiform needling can effectively relieve low back pain in patients with CNLBP,improve lumbar function,reduce local soft tissue edema,restore muscle elasticity,and lessen the impact of the condition on daily life.Compared with conventional acupuncture,it demonstrates superior therapeutic benefits.
