NIOSH researchers use an iPod app to assess whole-body vibration

By A.G. Mayton and Bryan Kim

Cumulative exposure to whole-body vibration (WBV) adversely impacts the health and safety of exposed mine workers. Mining equipment-induced vibration depends on factors such as equipment type, task and operator skill. Generally, it is time-variant and widely broadband in frequency content. Exposure to such vibration can also cause fatigue or reduce fine motor skills. Moreover, WBV may contribute to the development of musculoskeletal disorders (MSDs) of the spine among exposed workers.
