Measurement and Computational Procedures of Bioimpedance Analysis to Assess Human Postural Instability in Clinical and Space Medicine Research

The article presents data on preliminary studies aimed at developing a technology for prognosis of orthostatic instability of astronauts and volunteers under the action of unfavorable factors of space flight and carrying out preventive measures, particularly, during rotation on a short-radius centrifuge, functional orthostatic tests, and for patients with orthostatic instability. The technology proposed for the prediction of the development of syncope states is based on monitoring changes in the electrical resistance of regions of the human body.
