RESUMEN
This work was designed to develop a mathematical model based on the results of computed stabilometry in the subjects differing in the degree of resistance to motion sickness. The model is designed for the purpose of instant diagnostics in the course of occupational selection. Stabilometric characteristics of 61 men aged from18 to 24 years were compared with those obtained by the method of continuous cumulation of Coriolis accelerations. The accuracy of diagnostics with the use of stabilometry was estimated at 93.2%. It is concluded that computed stabilometry provides an efficacious tool for the assessment of sensitivity to motion sickness for the purpose of professional selection.

The present work was designed to estimate changes in the quality of the equilibrium function (QEF) and dynamic stabilization indices (DSI) of the vertical position of the body in comparison with the traditional stabilometric characteristics (the length and the area of statokinesigram, mean radius of body deviation, average linear centre of foot pressure displacement velocity). The computed stabilometric technique was used to study the equilibrium function in the patients (n=133) presenting with otorhinolaryngological problems and requiring the surgical treatment. It was shown that selected stabilometric characteristics (such as QEF and DSI) may be useful for control of the efficacy of the treatment of surgical patients; moreover, they can be applied to the evaluation of dynamics of the patients' health status during the postoperative period.

The authors provide a rationale for clinical studies of four types of rotational nystagmus, true vestibular, cervico-vestibular, opto-vestibular, and cervico-optovestibular. A physiological concept of nystagmus during active head rotation is formulated. Negative consequences of vestibular nystagmus as a pathophysiological reaction are discussed. The main criteria for nystagmometric differential diagnosis of peripheral vestibular and central disorders are proposed. Diagnostic potential of the new <

The necessity of studying the dynamic stabilization of the human body vertical position is substantiated. New capacities of a stabilometric vector analysis in diagnosing equilibrium dysfunction, evaluating the efficiency of treatment, and determining the statistical significance of differences in the results in a patient rather than in a group of subjects are shown.

Questions related to the rotary nystagmus generation in the different variants of interactions between the vestibular, optical, and proprioceptive sensory systems are considered. A physiological concept of the opto-vestibulo-cervical system is given. The biological expediency of nystagmus is considered. It is proved that nystagmus is the organism's position-finding (orientation) reaction directed to a search for the objects in space aiding human orientation. Certain ideas about the vestibulology and physiology of space perception are discussed in detail from the viewpoint of the integral system approach.

Rotation and caloric methods of vestibular stimulation proposed and adopted during the last decades have been reviewed in terms of their efficacy in differential and topic diagnosis, clinical practicability. Systemic and bio-cybernetics approaches to vestibular apparatus and function have been analyzed. The need of using neurophysiological and cybernetics methods for further progress in relevant research and most promising trends in advancing clinical vestibulometry have been determined.
