Abstract

Purpose : This study was to evaluate gait velocity and muscle activity on 3 different gait conditions in elderly women. Methods : There were one group was 20's generation(n=12), and the other group was over 60's generation (n=12). The velocity of gait was analysed for using the Footscan system, EMG(MP150) for muscle activity. Subjects were measured 3 gait condition(normal, obstacle-10cm, dual obstacle-10cm. Measured values were used by the independent t-test for analysing between groups, and repeated measurement of ANOVA for analysing within group. Results : The results were as follow: velocity and acticities of lower 4 muscles were significantly differences in experimental group. In control group, there were not significantly differences. Contrast-groups were significantly differences of velocity(obstacle, dual obstacle), muscle activities(soleus-dual obstacle, hamstring-all). Conclusion : These results indicate that elderly people are reduced gait ability in dual task, and obstacle gait. So Elderly women need to training obstacle/dual gait for preventing falling.
