Variation cardiointervalometry in evaluating the efficiency of medical and psychological rehabilitation measures of military services

Abstract

BACKGROUND: Тhe main tasks of medical and psychological rehabilitation (MPR): accelerated restoration of the functional state and working capacity of military personnel; increase of reserve capabilities; reduction of the influence of risk factors for various diseases; secondary prevention of chronic diseases and prevention of chronization of acute processes; carrying out measures to eliminate and reduce psychopathological syndromes in order to achieve mental adaptation; restoration of professional health, correction of maladaptosis.

AIMS: Is to study the informative value of variational cardiointervalometry (VCM) indicators in assessing the effectiveness of MPR of military personnel.

MATERIAL AND METHODS: This study was conducted in the branch Clinical Sanatorium “Volga” of the Federal State Budgetary Institution “Privolzhsky” of the Ministry of Defense of the Russian Federation during the work of the psychotherapy room with the category of MPR for 12 months. In addition to the regulated volume of diagnostic studies, the Device for psychophysiological testing UPFT-1/30 “Psychophysiologist” (manufacturer of LLC NPKF “Medikom MTD”, Russia) was used. One of the research methods is the assessment of the functional state of the heart rhythm by the method of variational cardiointervalometry (VCM) at admission to MPR and before discharge (also referred to in the literature as heart rate variability, HRV). The study was conducted with 116 servicemen undergoing MPR for fatigue of 1–2 degrees for 10 days. Representatives of the Strategic Missile Forces (RVSN) ― 34 people; aerospace forces (VKS) ― 32 people; ground forces (SV) ― 50 people. The data is processed in StatSoft Statistica 10 Russian Portable 10.0.1011.0 x86.

RESULTS: The average values for the entire group (116 servicemen): at admission and before discharge IN (stress index) increased statistically significantly from 284.5 to 359.7 cu; VLF-decreased from 21.1% to 16.0%; LF/HF (vagosympathetic interaction index) ― from 2.7 to 4.0 cu; Centralization index ― from 3.8 to 5.1 cu; PARS (indicator of adaptation of regulatory systems) ― from 4.6 to 5.3 cu. The result is a pronounced tension of regulatory systems, active mobilization of protective mechanisms, increased activity of the sympatho-adrenal system and the pituitary-adrenal system.

CONCLUSION: VCM (HRV) is one of the practical informative methods. RVSN: an increase in the voltage of regulatory systems as a reaction to physical exertion, a post-loading energy-deficient state, the index of vagosympathetic interaction has shifted to the parameters of the norm.VCS: an increase in the voltage of regulatory systems, an increase in the activation of the sympathetic nervous system, an active mobilization of protective mechanisms. SV: a tendency to reduce the voltage of regulatory systems, a post-loading energy-deficient state, a balanced state of the autonomic nervous system (VNS). A delayed training effect is likely, changes occur in the late phases of recovery, after the end of the rehabilitation period.
