CHARACTERISTICS OF SIMPLE MOTOR AUDITORY REFLEX OF RADAR OPERATORS TROOPS
This study was aimed to eveluate the reflex characteristics of sound stimuli of radar operators. Ninety radar operators aged between 18 and 48 were studied. The operators were divided into 3 groups of 18÷28 years (n = 50), 29÷38 years (n = 23) and 39÷48 years (n = 17). Same aged soldiers devoted administrative work (subgroups number 12, 8, 10, respectively) treated as control group. Physiological parameters test complex UPFT1/30 (Russian Federation) was used to perform simple auditory motor reflex test. Auditory reflex was measured by average reply time, minimum and maximum reply time, central nervous system activation level and stability of auditory reflex. Auditory reflex was tested twice for every person with 6 month intervals to appreciate the stability of characters measured over the time. Results of motor-audirory reflexes obtained (the average reflection time the level of activation of the central nervous system, the accuracy and stability) in the group of study and control group were within the limits or above the average value settled as standards of the complex used. The average reflection time value obtained for ages 18÷28 years was 177±4 ms - fairly good, for 29÷38 years old ages group were 185±8 and 187±5 ms for rest group for first measurement. In the second test, average reflextion time were 193±4, 201± 8 and 193±6 ms, respectively. The reflection time for both group of study and the control group tended to increase between the two measurements but for general group the difference between subsequential tests were not reach the level of statistically significance, however for most young persons (18÷28 years old) the difference was reliable. The average reflection time increased for this group what may be due to impact of negative factors of professional inveronment. It is the reason to draw more attention to the point of proffecional helth protection.
