Opis:
Head-brain injuries are a complicated and multidimensional problem, which include acute and chronic therapy as well as varied aspects of rehabilitation. Patient treatment after head-brain injury requires co-operation between physicians of various specialties, as well as psychologists and physiotherapists. A patient’s treatment outcome depends on many factors, with some enhancing and others impeding the rehabilitation process. A knowledge of these factors helps one to optimize the whole therapy process as well as to prevent its unfavorable course. The paper describes several neuro-psychiatric aspects of head injuries – connected particularly with diagnostics as well as disability benefit rulings. Every patient to undergo rehabilitation requires diagnostic verification – particularly a ‘difficult’ patient with complex dysfunctions including neurogenic ones. The revision requires sometimes even the fact of the occurrence of a head-brain injury or its primary intensity. The absence of a head injury or mild concussion in principle cannot result in future in a severe psychoorganic brain syndrome. The diagnostic incoherencies relating to the results of additional investigations (psychological tests, MRI and CT of the brain) in outcome states and their influence on disability benefit rulings were discussed. The size of the structural changes of nerve brain tissue at times does not correspond with the intensity of clinical symptoms. For example, the valuation of possible intellectual deficits seems to be more important than a confirming of the organic substrate. The value of patient motivation that influences positively the processes of rehabilitation and healing, or that at times determines merely those activities for the obtainment of disability benefits, for example, were emphasised.

Opis:
The performance of passive safety devices to protect vulnerable road users, or otherwise endangered persons, from severe injuries in cases of impacts and accidents has improved notably in recent decades. The devices’ levels of performance appear to have plateaued but the numbers of severe injuries and deaths caused in such incidents could be decreased further if new solutions are found. At first, the possibilities for improving the impact behavior of passive safety devices may appear to be restricted to device geometry; however, it is in fact also possible to rethink the applied materials and to utilize natural principles in their design. In this study, impact related brain injury mechanisms and injury criteria are investigated using dynamic simulations and Finite Element Head Models, results from which are compared with data collected from real-life accidents. As these tools are advancing considerably in terms of accuracy, information density and complexity, they provide, like expert knowledge from the fields of biomechanics, biomedicine and neuroscience, valuable input for further development.

Opis:
Motor vehicle crashes are one of the leading causes of traumatic brain injuries. Restraint systems of cars are evaluated by crash tests based on human tolerance data, however, the reliability of data currently used has been questioned several times in the literature due to the neglect of certain types of effects, injury types and uncertainties. Our main goal was to re-evaluate the currently applied risk curve by taking the previously neglected effects into account. Methods: In this paper, the probability of traumatic brain injury was determined by reliability analysis where different types of uncertainties are taken into account. The tissue-level response of the human brain in the case of frontal crashes was calculated by finite element analyses and the injury probability is determined by Monte Carlo simulations. Sensitivity analysis was also performed to identify which effects have considerable contribution to the injury risk. Results: Our results indicate a significantly larger injury risk than it is predicted by current safety standards. Accordingly, a new risk curve was constructed which follows a lognormal distribution with the following parameters: μLN = 6.5445 and LN = 1.1993. Sensitivity analysis confirmed that this difference primarily can be attributed to the rotational effects and tissue-level uncertainties. Conclusions: Results of the tissue-level reliability analysis enhance the belief that rotational effects are the primary cause of brain injuries. Accordingly, the use of a solely translational acceleration based injury metric contains several uncertainties which can lead to relatively high injury probabilities even if relatively small translational effects occur.
