The role of computerized dynamic posturography in the diagnosis of balance disorders
Piotr Olejarz, Grażyna Olchowik

Vertical posture stabilization can be obtained by reducing dislocations
of the centre of gravity in such a way that its vertical
projection does not move beyond the borders of the base of
support. The maintenance of the upright posture in humans
requires an analysis of signals from three sensory systems:
visual, proprioceptive and vestibular. Reflexes are the basis
of the physical activity necessary to maintain a stable upright
body posture.
Computerized dynamic posturography evaluates postural responses
based on stretch and vestibulo-spinal reflexes. Postural
responses are analyzed under sensory conflict conditions,
using moving support surface and variable visual environment
The paper discusses the use of computerized dynamic posturography
in the diagnosis of balance disorders and presents
the most frequent tests performed on the EquiTest system
developed by NeuroCom International, Inc.
