Phases of the motor act in stepping down movement (A). Reference times were measured from 2 curves (B). Top, The reference times plotted on the vertical velocity curve of the malleolus marker of the leading leg (T2) and of the supporting leg (T3) correspond respectively to the onset and offset of the movement phase. Bottom: lateral CP curve (T1) corresponds to the onset of CP change and Tbal to the end of the ballistic CP shift.
