In this study, we examined the effect of walking biomechanics, which occurs when the curvature of the walking path in virtual space is changed, while the actual walking path remains constant. Curvature gains and bending gains were used to change the virtual walking path. We found a significant difference in most biomechanical parameters when curvature manipulation and bending manipulation are applied compared with the case in which they are not applied. Some parameters were also suggested to depend on the visual sense or disagreement between the visual and other senses.
