||Shoulder disorders and postural stress in automobile assembly work
||Aug. 2000, Vol.26, No.4, p.283-291. Illus. 42 ref.
||A case-control study was conducted in an automobile assembly plant. The cases were 79 workers who reported shoulder pain and met symptom criteria in an interview. More than one-half also had positive findings in a physical examination. The 124 controls were randomly selected workers free of shoulder disorders. For each participant, the job was analysed for postural and biomechanical demands by an analyst blinded to case-referent status. 41% of the subjects flexed or abducted the right arm "severely" (above 90░) during the job cycle, and 35% did so with the left arm. Shoulder disorders were associated with severe flexion or abduction of the left (odds ratio (OR) 3.2) and the right (OR 2.3) shoulder. The risk increased as the proportion of the work cycle exposed increased. The findings support the conclusion that severe shoulder flexion or abduction, especially for 10% or more of the work cycle, is predictive of chronic or recurrent shoulder disorders.
