Influence of vertical and horizontal whole-body vibration on some psychomotor and cognitive functions of employees age 50+ (pilot study)

Abstract

This paper presents the pilot study on influence of vertical and horizontal vibration on some psychomotor and cognitive functions of employees at the age of 50+. Tests have been conducted in two series on special designed laboratory test bench for simulation of exposure to whole-body vibration. During the I series of tests, vertical vibration had acted on subjects and during II series horizontal lateral vibration had acted. Complex reaction time values obtained during I and II series indicates that there are no statistical significant differences between reaction of subjects on vertical and horizontal vibration. However slightly lower values during II series were noticed. Similar observations regarded results of cognitive function (attention and perceptiveness) tests.
