Purpose: The purpose of this study is to analyze the effect of pre-orientation of the pelvis on kinematic and kinetic variables of the lower extremity injury during 90˚SSC (side step cutting). This study is also to investigate the relationship between pelvic pre-orientation and lower extremity injury during the SSC.
Method: Nine healthy male college students participated in this study. Three dimensional motion analyses were used to analyze the kinematic and kinematic variables of A-SSC (typical SSC) and B-SSC (SSC which suppressed pre-orientation of the pelvis) during WAP (weight acceptance phase).
Results: The approach velocity reached to side cutting point was not significantly different between the two SSCs. Pelvic pre-orientation significantly decreased in the B-SC. The maximum ground reaction force and the location of the center of gravity significantly increased laterally in the A-SSC. Landing distance and last step length both increased with the B-SSC. The maximum angles of knee and hip were not significantly different except the valgus angle of knee joint. The knee valgus and internal rotation moment increased significantly in the A-SSC.
Conclusion: The length of the last step increased laterally in the B-SSC, but did not increase with the valgus and internal rotation moment of the knee joint. Therefore, even if the pelvic pre-orientation is suppressed during the SSC, it does not seem to have any negative effect on the non-contact knee injury.
