What causes whole body vibration
Vibration transmitted through the seat or feet (known as whole-body vibration or WBV)
Drivers of some mobile machines, including certain tractors, fork lift trucks and quarrying or earth-moving machinery, may be exposed to WBV and shocks, which are associated with back pain. Other work factors, such as posture and heavy lifting, are also known to contribute to back problems for drivers, however further study is needed into the impact of WBV.
