More quantitative information is needed to describe the relationship between mechanical exposure and musculoskeletal health as presented in the model. In this case it is recommended that in primary intervention studies not only changes in health outcomes be measured but also changes in mechanical exposure along the pathway of the intervention. In this way a better insight will be gained about the dose-response relationships between exposure to physical-load risk factors and work-related musculoskeletal disorders (WRMSD). More insight into these relationships will eventually lead to more efficient implementations of primary intervention strategies.
