Objectives : This study was aimed at comparing clinical effectiveness among pharmacopuncture treatment, Chuna treatment, pharmacopuncture-Chuna cooperative treatment for neck pain caused by traffic accidents. Methods : This study was carried out on the 87 patients with neck pain caused by traffic accidents. The patients were divided into 3 groups ; group A was treated with pharmacopuncture. group B was treated with Chuna treatment. group C was treated with pharmacopuncture and Chuna cooperative treatment one at a time. Also all groups were treated with general acupuncture and herb-medicine treatment. We measured visual analog scale(VAS) and neck disability index(NDI) before the treatment and 2, 4 weeks later. Results : In result each group had significant decrease in VAS and NDI after 4 weeks later. group C showed significant difference as compared to group A and B in NDI and VAS scores. In the first period(from pre to 2 weeks treatment) group C showed significant difference as compared to group A and B in VAS scores. Conclusions : According to the results of this study, it was suggested that chuna treatment and pharmacopuncture are effective in reducing neck pain caused by traffic accidents. Pharmacopuncture and Chuna cooperative treatment was more effective in reducing neck pain caused by traffic accidents.
