The authors present physiological ranges of values of seven parameters of stabilometric examinations of the upright posture in man. In order to make the examination effective, the authors suggested and tested three situations which make it possible to characterize the activity of the visual, vestibular and proprioceptive feedback in the process of maintenance of the upright posture. For measuring the supporting forces during the upright posture the authors used a stabilometer with automatic compensation of the body weight. Amplitude analysis of the obtained stabilometric curves was made "on line" by means of a microcomputer PMD 85-2. The mentioned stabilometric parameters make it possible to evaluate objectively the ability of the subject to maintain an upright posture based on a) the median amplitude and velocity of deviations of the body in an anterioposterior and lateral direction, b) complex parameters of the length of the curve, the total area and root mean square deviation of the statokinezigram.
