This study examined risk factors of falls through gait patterns in 21 elderly (71.3±4.9 years) and 21 young (20.2±1.3 years) subjects. The steps were counted with using a pedometer (LIFECORDER EX) over 14 days. The gait pattern was designed utilizing a three-dimensional motion analysis (Dipp-Motion Pro). The "rolling index (RI)" was defined based on the subjects' motion during gait. RI-right was greater than RI-left on 10cm of step width in the elderly subjects (F_<(1,29)>=8.97, p&<0.01). The subjects of each group were further separated into 2 groups to compare their physical activity. The group with greater physical activity showed a significantly higher wrist and toe swing in the elderly subjects (F_<(6,54)>=4.25, p&<0.005; F_<(1,13)>=6.33, p&<0.05; F_<(1,13)>=5.31, p&<0.05) These results suggested that the elderly subjects need to swing their hands and feet.
