Mechanisms of vibration-induced interference with manual control performance
Article Abstract:
An experiment was engaged in to explore the mechanism that may cause disruption of manual control performance during vibration exposure. The experiment was conducted in which 8 subjects performed three simple tasks in static conditions and during exposure to whole-body vertical (Z-axis) vibration at 0.5 and 4.0 Hz, at an acceleration magnitude of 2.1 meters per square second r.m.s. Vibrations of 0.5 and 4.0 Hz caused marked increase in control activity at frequencies of up to about 1 Hz compared to the condition without vibration.

Effects of duration and vibration on performance of a continuous manual control task
Article Abstract:
The effects of vibration on the ability to accomplish tasks were studied. Performance declined as a function of exposure time to vibration but did not negatively weigh on accomplishment of performance. Subjects tend to respond to perceived movements more slowly because of fatigue and reduced motivation over time. Fourteen healthy, right-handed male volunteers from the student and faculty body of University of Southampton participated in the study for five days in 1990.

Contrast thresholds and fixation disparity during 5-Hz sinusoidal single- and dual-axis (vertical and lateral) whole-body vibration
Article Abstract:
A study assumed that whole-body vibration impairs spatial retinal resolution and occulomotor alignment when transmitted through the seat. Contrast thresholds of the participants for horizontal gratings and the variability of vertical fixation disparity rose significantly when they were exposed to vertical motion.
