After ensuring postural stability a constant supply of information via different types of sensors is necessary as well as an efficient guiding activity of the CNS and a functioning locomotor system. Frequently the importance of exteroception is overlooked and the influence of the psychic state is omitted. The understanding of the principles of postural stability is significantly assisted by clinical findings of developmental kinesiology and investigation of pathological conditions in adult age. In the sphere of research in recent years the method of so-called stabilography is rapidly developing as well as the follow up of changes in the position ofCOPand other parameters by means of tensometric planes. For assessment of the centre of gravity (COM) 3D analysis can be used.
