Whole body vibration--a critical review

Abstract

Whole body vibration is an environmental stressor to which a substantial portion of the American workforce has been exposed. Numerous experimental studies have examined the acute effects of exposure to WBV but only in the last decade have the chronic effects been addressed. However, to date, no comprehensive review has been conducted of this common occupational exposure. This paper critically reviews the existing literature and summarizes the known health effects. Experimental study results are generally inconsistent and dependent on the characteristics of the vibration exposure. NIOSH's epidemiological studies have shown that several disorders are more prevalent in some occupations; however, causal relationships have not been established. Health professionals should be aware of potential ill effects that may result from exposure to WBV in combination with other environmental stressors.
