Circulatory Dynamics

In order to study the state of cerebral hemodynamics and to investigate the electroencephalographic characteristics in children with closed traumatic brain injury, 114 patients were examined. The children were examined in 6.1±0.8 months after a traumatic brain injury. To determine cerebral hemodynamics, transcranial dopplerography was performed, the functional state of brain was evaluated according to electroencephalography. In the course of the study, it was noted that a disordered cerebral hemodynamics in children with moderate and severe brain contusion and its foci presence was accompanied by a rise in a linear velocity of blood flow, while its decrease was found at the same contusion, but that was severe and with the presence of subdural, subarachnoid and epidural hemorrhage. Signs of diffuse changes in bioelectrical activity of the brain were represented by a significant increase in an amplitude of the alpha rhythm in children with closed traumatic brain injury of moderate and serious severities compared to mild one. Key words: children, craniocerebral injury, electroencephalography, transcranial Doppler sonography, paroxysmal activity.

Introduction. One of the main tools of an osteopath are soft tissue techniques, which have a number of particular qualities such as minimization of force and duration of indirect techniques with an emphasis on muscle and ligamentous structures; combination of gestures, tendency to maximal relaxation and exclusion of direct action on pathological symptoms such as tension, overtone and pain. Minimization of the force applied during the performance of soft tissue techniques often invites a question whether there are differences between the usual touch and the therapeutic touch of an osteopath.Goal of research - to reveal the changes in the bioelectrical activity of the cerebral cortex arising in the process of osteopathic treatment in order to prove its specifi city in comparison with nonspecifi c tactile stimulation (neutral touch).Materials and methods. 75 people were examined with the use of multiparameter analysis of multichannel EEG in different times. 25 patients were clinically healthy adults, whereas 50 patients had signs of somatic dysfunctions.Results. Computer encephalography permits to perceive the difference between the neutral touch and the therapeutic action. An identifi cation reaction is a response to the neutral touch (changes in brain bioelectrical activity with an increase in statistically signifi cant connections in the temporal lobes), whereas the therapeutic action provokes the state of purposeful brain activity during still point (intensifi cation of frontooccipital interactions).Conclusions. Osteopathic action causes additional tension in the processing of incoming information, which requires participation of different brain regions, including interhemispheric mechanisms associated with analysis, maintenance of attention and regulation of targeted activities.
