causes of vibration inside body
What causes whole body vibration. 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.
Exposure to. vertical vibrations in the 5-10 Hz range generally causes resonance in the thoracic-abdominal system, at 20-30. Hz in the head-neck-shoulder system, and at 60-90 Hz in the eyeball. When vibrations are attenuated in the. body, its energy is absorbed by the tissue and organs. The muscles are important in this respect. Vibration. leads to both voluntary and involuntary contractions of muscles, and can cause local muscle fatigue, particularly when the vibration is at the resonant-frequency level.
