Scientific and clinical biofeedback in the USSR.

This paper describes the history of biofeedback research and application in the USSR. The approach of USSR scientists to the study of basic mechanisms of biofeedback and the status of clinical applications of biofeedback in the Soviet Union are described. Trends in the publication of biofeedback-related papers in Russian are presented, and the present "state of the art" described. Promising prospects for biofeedback research and application are discussed.

[The mechanisms regulating pulse-wave spreading time in a biological feedback regimen in patients with borderline arterial hypertension and in healthy subjects].

The regulatory mechanisms of pulse transit time (PTT) during biofeedback training were studied by noninvasive cardiovascular monitoring in borderline hypertensive and normotensive subjects. Hemodynamic parameters were used as indirect indices of autonomous nervous system activity. All the patients were capable of increasing PTT. Systolic blood pressure demonstrated significant correlation with PTT. The effects were mediated by the different combinations of sympathetic and parasympathetic drives. In the initial 5 sessions, there was the most significant decrement of sympathetic, especially beta-adrenergic activity, expressed in the reduction of the myocardial contractility and cardiac output. In the retraining period (6 to 12 sessions), the leading role was played by the reduction of the arterial tone and total peripheral resistance. Respiratory arrhythmia rose in both cases as a result of the increased parasympathetic activity.

[A microcomputer system of biotechnical feedback].

A microcomputer system has been constructed and developed for biofeedback research and clinical biofeedback training. Hardware and software enable on-line data acquisition, storage and real-time analysis with visual feedback of chosen parameters, while changes in other physiological variables are recorded and monitored. The software handles control of experimental sessions, data reduction, statistics, data base management and output document forming. Computer analysis of pulse transit time biofeedback training with multiple cardiovascular monitoring in experimental and clinical setting outlined contributions of sympathetic and parasympathetic influences on observed patterns of cardiovascular modifications.
