Recent studies support the notion that a fatigue failure process may be responsible for the development of MSDs, including epidemiological studies, animal studies, and in vitro testing of musculoskeletal tissues. This study presents a new risk assessment model for the shoulder, which estimates the daily dose of the cumulative damage (CD) for the shoulder and allows the CD for multiple tasks to be summed to get an overall estimate for the daily cumulative damage. Videotapes of jobs from an existing epidemiological study from a large U.S. automotive manufacturer were analyzed to get exposure information required for the model. The model was then validated using outcomes from the epidemiological database. Logistic regression was used to assess the associations between Log CD and various shoulder outcomes. Results indicated that the cumulative damage for the shoulder was highly associated with all shoulder outcomes and that application of the fatigue failure methods also works extremely well in assessing the probability of association with shoulder outcomes. These results provide further support regarding the role of the fatigue failure process in the development of MSDs. |
