Exposure assessment strategies for work-related risk factors for musculoskeletal disorders.

摘要: The design of assessment strategies depends on the risk factors interest, features measurement device, feasibility considerations, and variation at workplace. selection variables should permit specific etiologic inferences. Several researchers have combined different methods into a broad array exposure measures. Other authors converted inputs from disparate common metric, varying subjective ratings to quantitative measures such as compression forces in lumbar back. parameterization an variable address 3 principal dimensions intensity, frequency, duration. Standardized expressions patterns been suggested. An alternative approach is modeling variability that allows for individual level. A related topic critical time window musculoskeletal disorders. This not only requires detailed information events over time, but also appropriate characterization episodic problems.
