Assessment of physical demands and comparison of multiple exposure definitions in a repetitive sawmill job: Board edger operator

Article Abstract:

The physical exposures in a sawmill job with a high incidence of upper extremity musculoskeletal injuries are described in terms of multiple measures of posture, exertion and frequency and the comparability of those definitions is examined. It is found that incidence of reported upper extremity musculoskeletal injuries in the two facilities are higher with the greater total exposure.
