[Occupational work capacity and functional status of an operator during repeated exposure to optokinetic and...

It has been shown that optokinetic stimulation that elicits sensory-autonomic manifestations of motion sickness and head-down tilt that simulates fluid redistribution in the cranial direction decrease professional abilities of the operator even after he has developed good skills. Repeated exposures to optokinetic stimulation or head-down tilt have some training effect. However, control tests that include both optokinetic stimulation and head-down tilt give evidence that their training effect is not adequate.
