Abstract
When walking in the forward direction, a person relies on active control from the CNS to maintain balance in the ML direction while stability in the AP direction is controlled by passive actions related to spinal reflexes and mechanical constraints (Kuo, 1999). However, walking in the ML direction causes a person to reverse control such that balance control patterns in the AP direction (direction of progression) indicate active control while passive actions for balance are implied in the direction orthogonal to progression (Wurdeman et al., 2012). It is not clear whether visual feedback contributes to this orthogonal separation of control between gait and balance.
This research attempts to quantify the effect of OF on this orthogonal shift in balance control in a graded fashion to isolate if the shift in orthogonality is graded or occurs at a specific threshold.
