Clinical study of nerve block therapy guided by electric stimulation in low back pain / 中国康复医学杂志

ABSTRACT

Objective:To observe the therapeutic effect of nerve block therapy guided by electric stimulation on the relief of pain and the improvement of function in patients with low back pain(LBP).Method:A total of 78 LBP patients were divided into nerve block treatment group(n=40)and traditional treatment group(n=38)randomly.The nerve block treatment group was injected with Betamethasone compound 2mg and Lidocaine 2ml guided by electric stimulation.The physical modalities and exercises therapy were applied in the traditional treatment group.The pain was evaluated with visual analogue scale(VAS)before treatment and 1 d,1 and 2 weeks after treatment.The function of lumbar was assessed before and after the treatment with performance assessment scale for the treatment of lumbar vertebral diseases.Result:The effective rate in treatment group was 100.0%,in traditional group was 86.8%the improvement rate in treatment group was 96.6%.in traditional group was 64.3%there were significant differences between two groups (P<0.01).Conclusion:Nerve block therapy guided by electric stimulation display significant effect on relief the low back pain and improve the function of lumbar vertebrae.
