summaryStanding is a skill of everyday life which requires the interaction of multiple sensorimotor processes. Deterioration of balance control is well known in old and diseased subjects. Despite years of research, strategies underlying functional performance in postural stability are not fully understood, yet. This can partly be explained as the amount of body sway is often solely used as the index of postural stability. However, the concepts of nonlinear dynamics suggest that variability in the motor output is structure rather than randomness and has a functional role e.g., adaptability to environmental stressors. The goal was to clarify control mechanisms behind upright stance with respect to various standing tasks. The quality of balance control was evaluated in terms of variability as beneficial to human movement organisation which gives rise to new interpretations.
