Abstract

The purpose of this study is to investigate the change of hamstring muscle relaxation and craniosacral reciprocal movement by using S. O. T. (sacrooccipital technique) categoryⅠ block-intervention process. 26 subjects with heel tension were randomly divided into two groups (EXP=13 and CON=13). This study carried out the category I block-intervention process on the experimental group and the false block-intervention process on the control group. Then, this study measured the sit-and-reach and sacral reciprocal movement of subjects before and after the intervention. The result values before and after the intervention were analyzed through ANCOVA by using SPSS PC Program (Ver. 20.0). In both investigations, the degree of hamstring muscle relaxation and the change of sacral reciprocal movement, there were statistically significant differences between the experimental group and the control group as [F(1, 23)=7.73, p<0.5] and [F(1, 23)=7.07, p<.05] respectively. According to the results of this study, it is expected that S. O. T category I bllock-intervention technique will have positive effect on both hamstring muscle relaxation and craniosacral reciprocal movement.
