Mean forward displacement of the COP and dominant hand on elevated surface.

<p>(a) Mean forward movement of the COP on a 1 m elevated surface in no touch (white) and touch (black) conditions for variables: Max - forward displacement of the CoP, Hold – average position of the COP in the end position that lasted 2 seconds; Sway - of the COP during a 2 second hold of the reach expressed as path length, Initial back - initial backward displacement of the COP during reach).(b) Mean movement of the hand during the reaching movement in the no touch (white) and touch (black) conditions. The significant differences are marked as **p<0.01; ***p<0.001.</p
