• Description:
  Objective: To estimate associations between biomechanical exposures and workplace neck and shoulder musculoskeletal disorders (NSMSDs) in a prospective cohort. Methods: Manufacturing workers (N=349) were followed for 28 months. Biomechanical exposures were collected on each individual and physical exams were performed every 4 months. Prevalent cases at baseline (N=30) were excluded from the analysis. Results: There were 18 incident cases of NSMSDs. Greater than 33% time in forceful hand exertion doubled the rate of incident NSMSDs. Greater than 18 degrees of shoulder abduction, during forceful hand exertion, increased the rate by 55%. Confidence intervals were wide. Conclusions: Effect estimates of the relationship between forceful hand exertions and NSMSDs were consistently elevated whether measured in isolation or while in shoulder abduction. Following a larger cohort with more frequent physical examinations would improve estimates of the model. [Description provided by NIOSH]
