The Ohio State University
The panel's effort to evaluate the scientific basis for a relationship between work factors and musculo-
skeletal disorders of the back and upper extremities required comprehensive reviews of the epidemiologic
literature. For each of the two anatomical regions, reviews of the physical and the psychosocial factors
were undertaken. Referring back to Figure 1.2, the review of the epidemiologic evidence addresses
several components. The workplace factors considered include all three main elements and their relation-
ship to the person. The person is considered in terms of the several outcomes reported in these studies,
while adjusting or stratifying for the individual factors that are relevant.

2.1.1 Criteria for Selection and Review of Articles
In planning for this process, the panel set a number of criteria specific to the task of selecting articles for
the epidemiology review:
.
Both the exposed and the nonexposed (or comparison) populations are clearly with explicit
inclusion and exclusion criteria. It is evident why subjects who were studied were eligible and
why those not studied were ineligible.
.
The participation rate was 70% or more.
.
Health outcomes relate to musculoskeletal disorders of the low back, neck, and upper extremities
and were measured by well-defined criteria determined before the study. The health outcomes
