Summary
Whole body vibration (WBV) exposure from vehicles and machinery may pose health risks, particularly to the spine. Long-term WBV exposure is linked to increased low back pain prevalence in drivers.
Area of Science:
- Occupational health
- Biomechanics
- Epidemiology
Context:
- Whole body vibration (WBV) exposure is common in occupational settings involving transport vehicles and machinery.
- The health risks associated with WBV exposure remain incompletely understood.
- Existing literature prior to 1992 was reviewed, necessitating an updated search for the period 1992-1996.
Purpose:
- To critically evaluate the scientific literature on the health effects of whole body vibration (WBV) exposure from 1992 to 1996.
- To synthesize findings from epidemiological, experimental, and review articles.
- To assess the potential link between WBV and back disorders.
Summary:
- A review of 53 articles (1992-1996) found methodological limitations in most epidemiological studies.
- Experimental data suggest WBV negatively affects the spine.
- Epidemiological studies indicate a probable dose-related association between WBV exposure and increased low back pain in drivers.
Impact:
- Findings suggest long-term WBV exposure may contribute to back disorders.
- Current research does not permit quantitative risk assessment of WBV exposure.
- Highlights the need for improved study methodologies in occupational health research concerning vibration exposure.
