[Dynamics of visual hand localization in the 24-hour observation of persons working under conditions of additional loads].

Examined--by means of a Starkiewicz's hand localizer--were 170 right-hand workers of a paper factory working in conditions of excessive noise and high temperature of the surroundings. Analyzed were 140 persons tested 4 times in the period of each production shift (6.00-14.00; 14.00-22.00, and 22.00-6.00). The analysis showed the maximal efficacy of the visual function of the hand localization in the range of the right-hand and in the course of the night shift in both age groups.
