Abstract:
This study focuses on arm swinging movements in gait for active self-healthcare. However, most of the research on arm swing movements is clinical approach and biomechanical mechanisms of why these movements are effective are not well understood. Therefore, this study aims to biomechanically elucidate the coupled process of arm swing and lower limb movement. This coupled process can lead to an effective gait according to his/her gait at the time. In this paper, we focus on the bimodality of vertical ground reaction force, which is also used for gait evaluation in clinical practice. The purpose of this paper is to experimentally clarify how the bimodality of vertical ground reaction force varies with arm swing, and to determine mechanistically what coupled processes are responsible for this variation. The experiment is carried out with four volunteers. In the experiment, each volunteer performs six different gait conditions. In these experiments, the ground reaction forces and mechanical parameters of each body segment are measured. The results of the analysis showed that an increase in the angle of lateral pelvic tilt and the vertical ground reaction force increased in the valleys and decreased in the part of late peaks, as the angle of arm swing increased. The angle oflateral pelvic tilt also showed a change in value at the same time as the late peak of the vertical ground reaction force. This suggests that the bimodality of verticalground reaction force is related to the pelvic lateral tilt movement induced by arm swing.
