Abstract

Purpose: The purpose of this study was to find out the difference motion of hip, knee and ankle joint during walking according to using walker on elderly people.
Method: Korean elderly people of 34 subjects was participated in this study. Participants was measured joint motion on hip, knee and ankle joint during both conditions (walking with walker and without walker). The measured data were analyzed using independent t-test to investigate the difference of joint motion on the both condition. The statistical analyses were performed using PASW for windows(Ver. 19) and p-value less than .05 were considered significant for all cases.
Result: The study showed that more joint motion on hip flexion and ankle pronation is increased by using walker. And hip extension, knee external rotation and ankle plantar flexion is decreased by using walker.
Conclusion: This study suggest that using walker on elderly people was change the motion of the lower limb joint during walking. Therefore, It is necessary to develop a new walker that can reduce dependency and ensure stability on elderly during walking.
