The purpose of this study was to investigate the difference of 3D angle in the lower extremity joint during elderly walking. Total of ten women elderly participated in this study and they were divided into two groups(70`s and 80`s) to ages. To accomplish this study, motion analysis was performed with 7 cameras(SF: 100Hz, ProReflex MCU, Qualisys, Sweden). Total of 13 reflective markers were attached on the participant`s joint and segment. The 3D angle of lower extremity joint was calculated by using Cardan`s method through Matlab 6.5 program. After data analysis, a independent t-test was performed to inspect whether statistically significant at the 5% level were found between groups using by SPSS 11.0. The results of analysis were as follows; First, in movement of the hip joint, at the mid stance(adductiobduction) and the complete landing and decelerated swing(internal/external rotation), it was found that 70`s group tended to show significantly further movement of abduction and external rotation than 80`s group on a statistical basis. Second, The movement in knee joint was indicated to have no statistically significant difference in flexion & extension, varus & valgus, and internal/external rotation. Third, in regard to the movement of ankle joint, it was found that 80`s group tended to show significantly further movement of plantar-flexion at landing, complete landing and decelerated swing than 70`s group on a statistical basis. And during accelerated swing, it was also found that 70`s group tended to show inversion, whereas 80`s group tended to show eversion. There were significant differences in the movement during said phase between two groups on statistical basis(p<.05).
