电针联合悬吊训练治疗慢性非特异性下腰痛的临床观察OA

Objective To observe the clinical efficacy of electroacupuncture combined with sling exercise therapy(SET)in the treatment of chronic nonspecific low back pain(CNLBP).Method Seventy-two patients with CNLBP were randomly divided into an observation group and a control group(36 cases each).The control group received SET,while the observation group was additionally treated with electroacupuncture at Jiaji(EX-B2)points.Changes in the visual analog scale(VAS),Oswestry disability index(ODI),and Japanese Orthopaedic Association(JOA)scores were evaluated before and after treatment.Surface electromyography(sEMG)parameters-root mean square(RMS)and median frequency(MF)-of the erector spinae and multifidus muscles were also compared between groups.Result After 2 weeks of treatment,the VAS and ODI scores in both groups were significantly lower than those before treatment(P＜0.05).At the end of treatment,the VAS and ODI scores were further reduced compared with both 2 weeks after treatment and baseline(P＜0.05).The observation group showed significantly lower VAS and ODI scores than the control group both after 2 weeks and at the end of treatment(P＜0.05).After 2 weeks of treatment,the JOA scores in both groups were significantly higher than those before treatment(P＜0.05),and the scores at the end of treatment were higher than those both at 2 weeks and before treatment(P＜0.05).The JOA scores in the observation group were significantly higher than those in the control group both after 2 weeks and at the end of treatment(P＜0.05).In the control group,the bilateral RMS values of the erector spinae and multifidus muscles showed no significant difference between 2 weeks after treatment and baseline(P＞0.05),but were significantly higher at the end of treatment compared with both baseline and 2 weeks(P＜0.05).In the observation group,the bilateral RMS values of the erector spinae and multifidus muscles were significantly increased after 2 weeks of treatment compared with baseline,and further increased at the end of treatment compared with both 2 weeks and baseline(P＜0.05).The observation group showed significantly higher bilateral RMS values of the erector spinae and multifidus muscles than the control group both after 2 weeks and at the end of treatment(P＜0.05).After 2 weeks of treatment,the bilateral MF values of the erector spinae and multifidus muscles in both groups were significantly higher than those before treatment(P＜0.05).At the end of treatment,the MF values were further increased compared with both 2 weeks and baseline(P＜0.05).The observation group showed significantly higher bilateral MF values of the erector spinae and multifidus muscles than the control group both after 2 weeks and at the end of treatment(P＜0.05).Conclusion Electroacupuncture combined with SET can more effectively relieve pain,enhance electromyographic activity of paraspinal core muscles(multifidus and erector spinae),and promote functional recovery of the lumbar core musculature.
