Freyss’ stabilometry and posturography- a comparison study
Abstract
The usefulness of conventional posturography when the changes of muscle tonus of the lower limbs affect position of the center of gravity which movement is measured is well known. The radius of the gravity center deflection such as length of the „way” and velocity of the movement can be calculated and compared during sequences with eyes opened, eyes closed and with feedback.
The Freyss’ stabilometer is an dynamic posturograph but its movement is limited to the only 2 axises: backward-forward and right-left. So it is no possibility to appreciate the real direction of the deflection of the platform during particular parts of the whole test. One may suggest that such a restriction of the movement can affect the results making them poorly objective. So, the aim of the study was to compare the static posturography and the stabilometry constructed according to the idea given by G. Freyss from Paris.
