The purpose of this study was to investigate the effect of medio-lateral pelvic asymmetry on the lower extremity kinematics during walking in female adults. To solve the research question three-dimensional motion analysis was performed with 7 infrared cameras(Proreflex MCU 240, Qualisys) with sampling frequency as 100Hz. Total of 10 female adults participated and they were divided into two groups: Asymmetric group(AG; n=5, age: 26.4±3.8 yrs, Pelvic tilt: 9±2.1 mm) and Symmetric group(SG; age: 25.6±3.2 yrs, Pelvic tilt: 2±1.0 mm). To determine their pelvic asymmetric level, Formatric-III was used. Total of 8-segmental rigid-link human body model(trunk, pelvis, left & right foot, shank and thigh) was used for this study. To find the group differences independence t-test was performed (α= .05). After data analysis following results were found. Firstly, for all of the 3-dimensional lower extremity joints pattern during walking, AG revealed similar pattern with SG. Secondly, for the asymmetric index, AG showed higher asymmetric indices of lower extremity joints than those of SG at most of events. The frequency of this pattern also increase at proximal joints compare with distal joints. Thirdly, for the knee joint, AG showed significant asymmetric difference compared with SG at HC of sagittal plane motion (p <.05). Finally, for the hip joint, AG showed the higher asymmetric indices than those of SG at TO and MSW of both frontal and transversal planes motion.
