| Research Abstract |
We used a particular computational approach, the uncontrolled manifold hypothesis, to explore the effects of visual stimulus on the composition of muscle groups (M-modes) and multi-M-mode synergies during whole-body sway tasks performed by standing elderly individuals. Visual stimulus led to the emergence of reciprocal M-modes that uniting dorsal and ventral muscles of the body respectively. Strong visual effects were also seen on the index of multi-M-mode synergies stabilizing the COP trajectory. The results suggest that visual stimulus can lead to improve the composition of M-modes and M-mode synergies in postural tasks involving large muscle groups.
