Purpose of work: to evaluate the reactivity of the spectral density of electroencephalogram theta rhythm power in military seafarers of the submarine fleet during the sanatorium-resort rehabilitation.Materials and methods: on the first and 20th day of the sanatorium-resort rehabilitation on the basis of the Crimean Sanatorium-Resort Complex and Sudak Health Center, the background activity of the electroencephalogram (EEG) was recorded with closed eyes and when performing a cognitive task in 60 seafarer divers.Results: analysis of variance showed significant changes in the spectral power of the EEG theta rhythm density in all experimental situations studied. In conditions of relative rest, the changes were expressed mainly in a decrease in the theta rhythm power. At the same time, when performing a cognitive task, multidirectional changes in the spectral density of the theta rhythm power were noted: an increase in the fronto-parietal direction of the predominantly left hemisphere and a decrease in other regions of the cerebral cortex.
This paper will discuss the perspectives of the marine medicine in the Crimean region, outlining key achievements from the collaboration between the Medical Academy Named after S. I. Georgievsky (Simferopol) and Sanatorium Sudak. As a result integral diagnostic approach of navy military personnel was provided by the research team ensuring that early most physical and psychic functional changes are revealed in time. Given approach with the main focus on most efficient measures is aimed to provide person-oriented rehabilitation techniques in terms of health resort accounting for the specific professional activity. Current research consists of a series of examinations made in accordance with the standardized methods for the functional state examination followed by the medical and psychological rehabilitation recommended by the Ministry of Defense of the Russian Federation as well as own approaches were applied for the assessment of adaptive responses. At this stage examination of the submarines’ crew members that was carried out during the entire health resort rehabilitation period suggests that for differentiation approach to be successful the assessments should consider the condition of the autonomic nervous system and highly sensitive parameters of the electroencephalographic recordings. As comparison of current standards and recommendations of medical and psychological rehabilitation with the efficiency of electroencephalography and heart rate variability recordings along with the psychological tests suggests that the latter provide better insights into the efficiency of rehabilitation and they should be included into the examination protocols. Assessment and further appropriate correction of microelement status should be also implemented as it ensures better functional and adaptive capacity.
