Information value of functional status of the stomatognathic system for postural balance regulation.

We performed cluster analysis of stabilometry data of 129 men and 122 women at the age of 20-60 years using the following 4 methods: European stabilometry variant, Romberg test (European variant), Romberg test (American variant), and Romberg test (American Universal variant). Results of factor analysis of primary data matrix obtained during the test "eye open-teeth clenched" attest to higher clinical significance of absolute stabilometry parameters in comparison with relative ones. The results of factor analysis revealed peculiarities of functional status of the stomatognathic system as the postural sensor and its effect on postural balance. The contribution of the functional status of the stomatognathic system into the postural balance is about 2%.
