The Relationship Between Arm Movement and Walking Stability in Bipedal Walking

The research about the bipedal locomotion is advanced in all fields at present. To the research of those fields, a quantitative analysis of human’s walking characteristic is indispensable. However, bipedal locomotion analysis has been performed focusing on lower limbs, and, as for research of the arm swing operation is not performed nevertheless it importance is generally told. The reason for it is to be assumed that the arm is not a necessary a part for locomotion. But it can be guessed that the arm swing operation having done a certain role about the stability of a walk which is very unstable physically. When running, the human clearly draws the arm greatly and quickly. This suggests the arm swing operation is related with the change of walking form and the move speed of the locomotion, and it influences the stability of a walk. This method becomes the useful analysis technique also not only to the above-mentioned research but to the sport kinematics research etc., if the relations to this arm swing operation and the stability of a walk is quantitatively understood. In this study, the relationship between arm swing operation in bipedal locomotion and stability of the walking was noticed.
