Errors between the Perceived Toe Height and Actual Toe Height

2013 Journal of the Society of Biomechanisms  
This study focused on the features of the perceived foot heights which could be a factor of the risk of tripping during walking. We measured and evaluate the errors between the perceived foot heights and actual foot heights. Ten young adults, whose lower visual fields were occluded, were asked to adjust their toe height to the height of the target test-piece that placed on the floor 3[m] ahead of them. Once they felt that their toe height was appropriately matched to the target height, the

The amount of the constant error tended to increase in negative direction. Moreover, such features were consistent with the features of the joint position senses that reported previously. These results indicate that as the participants raise their toe higher, the heights of their toe tend to become lower than they expected.
