Objectives : To examine the effects of JSO multi-treatment for whiplash injury patients by traffic accident. Interventions : Nonrandomized, Nonblinded compartson of the JSO+Acupuncture and Acupuncture Treatment. Main Outcome Measures : Subjective evaluation was followed by Clinical Grade and VAS after 5 times treatments. The SPSS 10.0 for windows was used to analyze the date and the Wilcoxon signed rank test and Mann-Whitney U-testwere used to verify the results. Results : The following results were obtained ; 1. Clinical Grade of the JSO+Acupuncture treatment was centralized to Gr II(50%) before treatment. After 5 times treatments, it was centralized to Gr I(58.3%). Also Clinical Grade was significantly changed from GR ll to Gr I(p<0.0002). 2. Clinical Grade of the Acupuncture treatment was centralize(d) to Gr II(54.2%) before treament. After 5 times treament, it was tend to cenualize to Gr I(50%). But Clinical Grade was still remained at Gr II(p<0.001) 3. VAS of change between JSO+Acupuncture and Acupuncture treatment, Vas of JSO+Acupuncture was significantly decreased (p<0.003). C onclusion : It is suggested that JSO multi-treatment has development-effectiveness on whiplash injury patients by traffic accident.
