Helkroppsvibrasjon

Helkroppsvibrasjon, often abbreviated as WBV, refers to the exposure of the entire human body to mechanical vibrations. This can occur in various environments, including occupational settings and during recreational activities. In the workplace, common sources of helkroppsvibrasjon include operating heavy machinery like excavators, trucks, tractors, and industrial tools. It can also be experienced as a passenger on buses, trains, or boats.

The effects of helkroppsvibrasjon on the human body are a subject of ongoing research. Prolonged and intense exposure has been associated with a range of health issues, particularly musculoskeletal disorders affecting the lower back, neck, and shoulders. Symptoms can include pain, stiffness, and reduced mobility. Additionally, some studies suggest potential links to cardiovascular and neurological effects, though more conclusive evidence is needed.

Several factors influence the impact of helkroppsvibrasjon, including the frequency and amplitude of the vibrations, the duration of exposure, and the posture and physical condition of the individual. Vibration transmitted through the seat is a common pathway for exposure.

Preventive measures are crucial for mitigating the risks associated with helkroppsvibrasjon. These can include engineering controls such as improving vehicle suspension systems and designing less vibrating machinery, as well as administrative controls like limiting exposure time and implementing job rotation. Personal protective equipment, such as anti-vibration gloves, may offer some limited protection for specific body parts but are less effective for whole-body exposure. Regular health surveillance for exposed workers is also recommended.
