Maltsev A. Psychophysiological effectiveness of working capacity rehabilitation in military combat veterans

The dissertation considers the study of transformation specifics of the military combat veterans’ functional status and identification of the most informative psychophysiological parameters indicating military veterans’ performance and functional status to develop assessment approaches and predicting effectiveness of their working capacity and health rehabilitation. The dissertation presents a comprehensive analysis of “combat environment” stress factors affecting considerably the development of stress in combat veterans. It has been shown that these factors’ impact explains 59.8% of total analysed data dispersion. The affinity defined of certain stress factors, which allows generalizing the idea of combat environment impact on the military, and determining their key components. It was found that the factors of “support organizations” cause different in expressiveness feelings in different subgroups of military. The subgroups identified of “hypersensitive” and “hyposensitive military”, whose impressions regarding impact of the harmful combat environment factors differ significantly (p <0.05). It was defined that the total contribution of “support organizations” stress factors to stress development in combat veterans of “hypersensitive” group explains 68.3% of total dispersion, and 49.9% – in “hyposensitive” group. The regularities identified of “spontaneous” recovery in functional status, physical and mental capacity of combat veterans after their return from the combat zone. It is shown that those military, who rested less than one month after returning from the combat zone, have a psychophysiological indicators decrease from 8.8% to 14.7%, and suite of metrics stabilization, such as heart rate and physical performance, with no use of targeted preventive and rehabilitation measures occurs on average in 100 days. A suite of informative psychophysiological metrics defined (reaction to a moving object, functional mobility of nervous processes and indicators reflecting human mobilization level in the performance of tasks, as well as activation level of the autonomic nervous system) to assess rehabilitation effectiveness in the hospital setting. It was found that those military referred for inpatient rehabilitation after returning from the combat zone, had their psychophysiological indicators improved from 10.6% to 12.1%, heart rate improved from 12% to 41.4%, which indicates an increase in their working capacity level, mobilization level and stabilization of fluctuations in functional status. Thus, the effectiveness of 20-day rehabilitation in hospital setting is superior to that observed in “spontaneous” recovery, which may indicate a significant usefulness of treatment and rehabilitation procedures. The information technology developed to evaluate the level of psychophysiological qualities reflecting working capacity, functional status health in healthy and injured military.
