WORK-RELATED SHOULDER-NECK COMPLAINTS IN INDUSTRY: A PILOT STUDY

Abstract

Twenty-six industrial workers, selected from employment records, were examined with a questionnaire, anthropometric measures, muscle strength measurements and filming during work cycles to study the influence of ergonomic factors on shoulder-neck complaints. No differences were observed when comparing age or anthropometric measurements between the nine workers with and the 17 without shoulder-neck complaints. Significantly weaker shoulder muscles were found in workers with shoulder-neck complaints than in those without. A higher median strain on the shoulders in the working situation of workers with shoulder-neck complaints than in the group with no complaints was suggested from the results of a biomechanical analysis of the different work tasks.
