Instability manifests as an exaggeration of the COG sway and is the expression of the difficulty encountered in resisting the destabilizing effects of gravity.
The amplitude of the COG sway, therefore, is representative of an individual's difficulty in achieving balance, and the amplitude and velocity of the sway are proportional to the difficulty experienced counteracting gravity.
The COG sway can be measured by computer analysis of information received from a forceplate on which stands the individual to be evaluated.
