The purpose of this study is to evaluate the difference about pathogenesis of normal person and traffic accident, author used DSOM to investigate pathogenesis. Patient group is consisted of people who one month does not pass from traffic accident, and normal group is consisted of people who do not have special symptoms and past history. DSOM was used for pathogenesis investigation of two group. There was significant difference between T.A. group and Normal group in deficiency of blood (血虛), stagnation of qi(氣滯), blood stasis(瘀血), dampness(濕), dryness(燥), liver (肝), heart(心), kidney(賢), phlegm(痰)(p<0.05). When it comes to comparison of sex, there was significant difference between male and female in dryness(燥), spleen(脾), and lung(肺)(p<0.05) in T.A. group. But in normal group, there was not significant difference between male and female, and in the case of male there was significant difference between T.A. group and normal group in deficiency of blood(血虛), stagnation of qi(氣滯), kidney(賢), phlegm(痰)(p<0.05). Also in the case of female there was significant difference between T.A. group and normal group in blood(血虛), stagnation of qi(氣滯), blood stasis(瘀血), dampness(濕), dryness(燥), kidney(賢), phlegm(痰)(p<0.05). This result showed that the pathogenesis are differs. This result showed that the pathogenesis of traffic accident patient and normal people are difference.
