Methods : This clinical study was carried out on 92 patients with low back pain and radicular pain diagnosed with HIVD, who had been admitted from Mar. 2011 to Dec. 2011. 60 patients were divided into two groups, group A and group B, of 46 patients each. Group A was treated with electro-acupuncture treatment and general acupuncture treatment twice per day for more than 2 weeks. Group B was treated with general acupuncture treatment twice per day for more than 2 weeks. Verbal numerical rating scale(vnrs) and Oswestry disability index(odi) were used to evaluated the effectiveness of the Oriental medical treatment. Results : In both two groups, VNRS, ODI, patient s condition grade decreased significantly in ststistics as treatment was perfomed. Between the two groups there was no significant difference in the VNRS, patient s condition grade. But there was significant difference in the ODI. Conclusions : These results suggest that both electro-acupuncture and general acupuncture were effective in reducing low back pain and radicular pain caused by HIVD. More systematic clinical stuty on electro-acupuncture is needed. Key words : Low Back Pain, Radicular Pain, Lumbar HIVD, Electro-acupuncture Treatment 119
