The article presents the modern informative algorithms for evaluating statokinesiogram in stabilometric research, based on variational analysis of the data array of linear vectors of a statokinesiogram. Algorithms are described for calculating and physiological interpretation of the main indicator of a statokinesiogram vector analysis ― Quality of balance function (QBF). The modern approaches to vector analysis are described ― estimation of the processes of dynamic stabilization of the vertical posture of a human being. Calculation of an integral value in this research ― Index of dynamic stabilization (IDS) ― for the first time allowed to take into account all characteristics of the simultaneously happening linear and angular deflection of the pressure center of the feet, i.e. to estimate the oscillating motion of the vertical posture stabilization as it is, without artificial division into indispensible components.

Key words: statokinesiogram, pressure center of the feet, vector analysis, linear vector of a statokinesiogram, variation of vector values, quality of balance function, dynamic stabilization of the posture, linear deflection of the pressure center, angular deflection of the pressure center, index of dynamic stabilization, energy expenditures when keeping the posture.
