The purpose of this study was to investigate effects of on-line modulation of visual and/or vestibular stimulations on human walking and postural control, and to see plasticity of human control of posture by adapting to visual and vestibular on-line modulations. We found that human control of posture and walking can be quantitatively modeled by a weak fusion of weighted linear summation of visual and vestibular information. The weights for vision and vestibular sense were different for individuals and could be changed into the direction of long-term adaptation of visual or vestibular on-line modulation with voluntary movements.
