INFLUENCE OF POSTURAL CORRECTION HEMODYNAMICS ON HEART RATE PARAMETERS

We have studied the application of postural effects (PE) in rehabilitation purposes and characteristics of reactions to PE. We did a survey of publications devoted to the study of the processes occurring in body dynamically changing position. The results are well-known research on separate fragmented systems and estimated parameters, and sometimes controversial and that the physiological basis of these processes is not fully understood, despite numerous studies in this area. We have learned that the hemodynamic responses are associated with duty cycle with a significant redistribution of blood in the body and thus largely opposed to orthostatic and antiorthostatic PE under which alternate deposition in blood vessels of the lower and upper parts of the body is accompanied by a vasoconstrictor and vasodilator vascular reactions. It is substantiated the use of dynamic PE to achieve certain positive hemodynamic responses. They are compared ways to use PE for therapeutic purposes. This article describes a prototype of the computerized system for dynamic PE and patient assessment. The reactions of the cardiovascular system to simple dynamic PE (HRV in particular) are researched. Our studies show regular variation indices of cardiac rhythm after PE.
