Objectives: First indetified were the average values for selected tests from the area of fine and gross motor skills in sober individuals, and then the values with an increasing level of alcohol in blood. Assess an immediate effect of alcohol on selected task and differentiate whether or not are fine and gross skills affected upon the same alcohol level in blood.
Methods: 12 probands (6 women and 6 men), who were tested for fine motor skills using three non-standardized test modified or created for the purpose of this experiment: threading beads on a string, unlocking locks and dropping coins to a moneybox. Gross motor skills were tested using stabilometric platform in a standard position with legs together nad with open eyes for 30 seconds.
The observed parameter was the track of COP. In each subsequent round every proband was administered 0,3g of alcohol per kg of weight.
The total rounds was six. Approximate values of alcohol in blood were measured continuously by Dräger Alcotest 7510.
Results: Both fine and gross motor skills were to a certain extent affected already of the first dose of alcohol.
