   A major problem for human standing posture is the high centre of gravity (COG) maintained over a relatively small base of support. The body, therefore, has a high potential energy, leading to priority of equilibrium control during almost all motor tasks including quiet standing.

  The task of equilibrium maintenance has sensory and motor parts that are interconnected. Another popular subdivision of this posture and motor control task is to its central and peripheral parts.

  Currently, the studies, which dealth with the motor and peripheral parts of the equilibrium task overwelmingly prevails. Similarly, studies of locomotion prevails compared to the studies of quiet stance and reflex-oriented studies prevails enormously over those dealing with cortical processes.

  It is widely accepted that human standing balance depends on an accurate integration of somatosensory, visual and vestibular cues. Pieces of information derived from those systems have to be welded into a unitary multisensorial postural message because no one sense directly measures the position of center-of-gravity relative to the supporting surface.

  A dysintegration of this message or its misinterpretation will cause a sensory conflict, which will affect the standing balance.

  Our project united efforts of a small interdisciplinary team of scientists from three institutes of the Bulgarian Academy of Sciences: Institute of Neurobiology, Institute for Population and Human Studies and Institute of Information and Communication Technologies and is supported by the National Science Fund in Bulgaria (Grant TK02/60).
