Streszczenie
Difficulties encountered in the assessment of psychomotor disturbances of persons under the influence of certain medicines have led to a search for new objective investigative methods. It seems that posturography could contribute significantly in this matter. In the paper, parameters obtained from the analysis of stabilograms of persons under the influence of alcohol or chlorpromazine were compared. Using the Langevin equation, the diffusion matrix and the friction coefficient were calculated. It was shown that closing the eyes causes an increase in the value of the diffusion matrix trace. Both the administration of alcohol and chlorpromazine cause a decrease in the value of the friction coefficient when the test is performed by persons with eyes closed. The friction coefficient can be proposed as a parameter which allows us to evaluate the state of the posture control system.
