Objectives : The purpose of this study is to investigate the effect of Chuna treatment for neck pain patients caused by traffic accident. Methods : 64 patients were divided into two groups, experimental group and control group, of 32 patients each. Control group was treated with general korean medical treatment three times per week for 2 weeks. Experimental group was treated with Chuna treatment and general korean medical treatment three times per week for 2 weeks. We evaluated the treatment effect of each group with the visual analog scale(VAS) and neck disability index(NDI). Results : 1. In both two groups, VAS were decreased significantly in statistics after treatment. 2. In both two groups, NDI were decreased significantly in statistics after treatment. 3. There were significant reduction of the VAS in experimental group than control group, but, there were not significant reduction of the NDI in experimental group than control group. Conclusions : We suggest that Chuna treatment could be recommended as a useful therapy to neck pain patients caused by traffic accident.
