Our results showed that the most appropriate rib's level for applying force was below the apex of scoliotic spine. From this appropriate level, the stress delivered to its conjunctive vertebra was the highest, as 1.3~1.8 times compared with others. Furthermore, the correction of Cobb's angle was also the highest, achieved 15%. The ML force was dominant in alteration of Cobb's angle, whereas the AP force was dominant in alteration of axial vertebral rotation. In addition, initial vertebral rotation influenced neither correction nor stress.
