Exposure to Hand-arm Vibration and Health Effects among Metalworkers

A recently published study informs about the dose-response relationship between
exposure to hand-arm vibration and health Eefects among metalworkers. The aim
of this study was to explore the relationship of exposure to hand-arm vibration
(HAV) and vascular, sensorineural and musculoskeletal symptoms and symptoms of
carpal tunnel syndrome (CTS) in a population of Finnish metalworkers.

As a result the authors conclude that there seems to be a dose-response
relationship between the cumulative lifetime vibration dose of the HAV and
finger blanching, sensorineural symptoms, symptoms of CTS and musculoskeletal
symptoms of upper limbs and neck in the group of metalworkers of the study. The
risk for neurosensory symptoms was the most significantly related to exposure
to HAV and also to impulse vibration. Further studies are needed to confirm the
present results also in other occupational groups taking into account the
possible synergistic effect of workload as well.
