The purpose of this study was to assess the symmetrical movements of the arms during walking to prevent falling. In this study, we developed a measurement and analysis system to assess walking movements objectively. In addition, index values were calculated as the symmetry of arm movements. Five healthy participants performed two tasks. The first task was straight walking. The second task was straight walking with weight attached to one arm. The results showed high index values of the swinging arms in both tasks. The index values of the bending arms were greater in the first task than in the second task. Consequently, the index values indicated the symmetrical movements of walking.
